x264 Revision Memo (13xx)

2009-12-16T05:46:00.000+09:00

r1376

Don't do sum/ssd analysis if weightp == 1
Typo fixes in comments and help.

r1375

Fix two bugs in 2-pass ratecontrol
last_qscale_for wasn't set during the 2pass init code.
abr_buffer was way too small in the case of multiple threads, so accordingly increase its buffer size based on the number of threads.
May significantly increase quality with many threads in 2-pass mode, especially in cases with extremely large I-frames, such as anime.

r1374

Avisynth-MT and 2.6 compatibility fixes
Explain to the user why YV12 conversion is forced with Avisynth 2.6.
Fix encoding with Avisynth-MT scripts by inserting the necessary Distributor() call; speeds such scripts back up to expected levels.

r1373

Fix zone parsing on mingw
Due to MinGW evidently being in the hands of a pack of phenomenal idiots, MinGW does not have strtok_r, a basic string function.
As such, remove the dependency on strtok_r in zone parsing.
Previously, using zones for anything other than ratecontrol failed.

r1372

More lookahead optimizations
Under subme 1, don't do any qpel search at all and round temporal MVs accordingly.
Drop internal subme with subme 1 to do fullpel predictor checks only.
Other minor optimizations.

r1371

Various minor missing changes from previous commits
Boolify sliced threads too
Remove unused constants from dct-a.asm
Fix a few typos/minor errors in preset documentation

r1370

Fix regression in direct=auto/temporal in r1364
Bug caused rare race condition in frame reference handling.
This resulted in invalid bitstreams in some B-frames and, very rarely, crashes.

r1369

Add fast pskip to x264 SEI info header

r1368

Minor seeking fix with Avisynth input
Seeking past the end of the input with --seek would result in the same frame being repeated over and over.

r1367

Add support for MB-tree + B-pyramid
Modify B-adapt 2 to consider pyramid in its calculations.
Generally results in many more B-frames being used when pyramid is on.
Modify MB-tree statsfile reading to handle the reordering necessary.
Make differing keyint or pyramid between passes into a fatal error.

r1366

Use aliasing-avoidance macros in array_non_zero

r1365

MMX version of 8x8 interlaced zigzag
Just as fast as SSSE3 on Nehalem (and faster on Conroe/Penryn), so remove the SSSE3 version.

r1364

Bring back slice-based threading support
Enabled with --sliced-threads
Unlike normal threading, adds no encoding latency.
Less efficient than normal threading, both performance and compression-wise.
Useful for low-latency encoding environments where performance is still important, such as HD videoconferencing.
Add --tune zerolatency, which eliminates all x264 encoder-side latency (no delayed frames at all).
Some tweaks to VBV ratecontrol and lookahead (in addition to those required by sliced threading).
Commit sponsored by a media streaming company that wishes to remain anonymous.

r1363

Add more detailed help for presets/tunes/profiles
Shows what options they represent.

r1362

qpel RD no longer needs mbcmp_unaligned

r1361

ensure that all boolean options are {0,1} so they print consistently in the options SEI

r1360

Actually do r1356
Somehow commit r1356 got lost in the ether.  I'm not sure how, but now it's fixed.

r1359

Remove some unused code from x264.c

r1358

SSSE3 version of zigzag_8x8_field
Slightly faster interlaced encoding with 8x8dct.
Helps most on Nehalem, somewhat disappointing on Conroe/Penryn.

r1357

Fix crash in interlaced with >8 refs
Crash introduced in weightp.

r1356

Significantly faster qpel-RD
Cache the results of MC, like in bidir-RD.
Slightly changes output due to the necessary reordering of satd/RD calls.
5-10% faster qpel-RD.

r1355

Add x264 prefix to functions with ffmpeg equivalents
Not important now, but will be when we add libav* input support.

r1354

10L in r1353
Broke mp4 output.

r1353

Enhanced Avisynth input support
Requires avisynth_c.h from the Avisynth API headers.
Reports errors properly from Avisynth script input.
Automatically construct input scripts for almost any input file.
Tries ffmpegsource2, DSS2, directshowsource, and many other sourcing methods, based on the input file extension.
Automatically converts to YV12.

r1352

Much faster weightp
Move sum/ssd calculation out of lookahead and do it only once per frame.
Also various minor optimizations, cosmetics, and cleanups.

r1351

Fix bugs in fps/timestamp handling in FLV muxer

r1350

Fix bug in weightp analysis
Weights weren't reset upon early terminations, so old (wrong) weights could stick around.
Small compression improvement.

r1349

Minor deblocking optimization, update comments

r1348

Fix weightb with delta_poc_bottom
Has no effect yet, but will be required once we add TFF/BFF signalling support in interlaced mode.
Gives 0.5-0.7% better compression with proper TFF/BFF signalling.

r1347

Give more meaningful error if 1st/2nd pass resolution differ

r1346

Fix extremely rare deadlock with sync-lookahead
Patch partially by Anton Mitrofanov.

r1345

Only print weightp stats if there were P-frames

r1344

Faster lookahead with subme=1
If it hasn't been clear already, don't use subme=1 as a "fast first pass" option.
Use subme=2 instead; 1 and below now enable a fast (lower quality) lookahead mode.

r1343

Faster weightp analysis
Modify pixel_var slightly to return the necessary information and use it for weight analysis instead of sad/ssd.
Various minor cosmetics.

r1342

Fix two issues in weightp
If analysis decided on an offset of -128, x264 would create non-compliant streams.
Fix some cases with nearly all intra blocks where analysis could pick very weird weights.
Also add some asserts to check compliancy.

r1341

Allow compilation with non-Apple GCC on OS X

r1340

Use __attribute__((may_alias)) for type-punning
GCC thinks pointer casts to unions aren't valid with strict aliasing.
See http://gcc.gnu.org/onlinedocs/gcc-4.4.2/gcc/Optimize-Options.html#Type_002dpunning.
Also use M32() in y4m.c.
Enable -Wstrict-aliasing again since all such warnings are fixed.

r1339

100l in deadlock fix

r1338

FLV muxing support

r1337

Fix rare deadlock introduced in weightp

r1336

Actually add -Wno-strict-aliasing to configure

r1335

Various weightp fixes
Make weightp results match in threaded vs non-threaded mode.
Fix two-pass with slow-firstpass.

r1334

Fix all aliasing violations
New type-punning macros perform write/read-combining without aliasing violations per the second-to-last part of 6.5.7 in the C99 specification.
GCC 4.4, however, doesn't seem to have read this part of the spec and still warns about the violations.
Regardless, it seems to fix all known aliasing miscompilations, so perhaps the GCC warning generator is just broken.
As such, add -Wno-strict-aliasing to CFLAGS.

r1333

Fix 10l in weightp on ARM

r1332

Fix one (of possibly many) miscompilations in weightp
Use NOINLINE and some emms calls to fix emms reordering issues.
This issue occurred with some GCC versions if threads > 1 and the phase of the moon was right.
Also a cosmetic in x264.c.

r1331

Fix pixel_ssd on win64
Didn't preserve XMM registers, may or may not have caused problems.

r1330

Fix weightp logfile parsing on MinGW

r1329

cosmetics

r1328

Fix weightp on ARM + PPC
No ARM or PPC assembly yet though.

r1327

Weighted P-frame prediction
Merge Dylan's Google Summer of Code 2009 tree.
Detect fades and use weighted prediction to improve compression and quality.
"Blind" mode provides a small overall quality increase by using a -1 offset without doing any analysis, as described in JVT-AB033.
"Smart", the default mode, also performs fade detection and decides weights accordingly.
MB-tree takes into account the effects of "smart" analysis in lookahead, even further improving quality in fades.
If psy is on, mbtree is on, interlaced is off, and weightp is off, fade detection will still be performed.
However, it will be used to adjust quality instead of create actual weights.
This will improve quality in fades when encoding in Baseline profile.

Doesn't add support for interlaced encoding with weightp yet.
Only adds support for luma weights, not chroma weights.
Internal code for chroma weights is in, but there's no analysis yet.
Baseline profile requires that weightp be off.
All weightp modes may cause minor breakage in non-compliant decoders that take shortcuts in deblocking reference frame checks.
"Smart" may cause serious breakage in non-compliant decoders that take shortcuts in handling of duplicate reference frames.

Thanks to Google for sponsoring our most successful Summer of Code yet!

r1326

Fix assert failure in the case of forced i-frames
Note that this applies to non-IDR i-frames, not IDR-frames.
This fix is also required for future open-gop.

r1325

Fix issues relating to input/output files being pipes/FIFOs

r1324

Various ARM-related fixes
Fix comment for mc_copy_neon.
Fix memzero_aligned_neon prototype.
Update NEON (i)dct_dc prototypes.
Duplicate x86 behavior for global+hidden functions.

r1323

Fix miscompilation with gcc 4.3 on ARM
Aliasing violation in spatial prediction caused nasty artifacts.
Shut up two other GCC warnings while we're at it.

r1322

Fix extremely rare infinite loop in 2-pass VBV
Implicit conversion from double->float lost enough precision to cause the loop termination condition to never trigger.
Bug report by Tal Aloni.

r1321

Fix large file support, broken in r1302

r1320

Dramatically reduce size of pixel_ssd_* asm functions
~10k of code size eliminated.

r1319

fix bottom-right pixel of lowres planes, which was uninitialized.
weirdly, valgrind reported this only with --no-asm.

r1318

Further reduce code size in bime
~7-8 kilobytes saved, ~0.6% faster subme 9.

r1317

Fix case in which MB-tree didn't propagate all data correctly
Should improve quality in all cases.
Also some minor cosmetic improvements.

r1316

Take into account chroma MV offset during interlaced motion search
Small improvement in interlaced compression.

r1315

Slightly faster ssse3 width4 chroma MC
Cacheline-aware in the same fashion as width8, but not conditional.

r1314

Eliminate some rare cases where MB-tree gave incorrect results in B-frames
Also get rid of some unnecessary memcpies.

r1313

Fix cases in which b-adapt 1 could result in AUTO-type frames.
This didn't actually cause any issues, but it removes the need for the fixing-up code that prevented said issues.

r1312

Motion compensation optimizations
Turning off inlining saves a whole boatload of code size for near-zero speed cost.
Simplify offset calculation.
Various other optimizations.

r1311

Minor CAVLC optimizations

r1310

cosmetics

r1309

ISC-license x86inc.asm
As the assembly abstraction layer is very useful in non-x264 projects, it is now ISC (simplified BSD) so that others, even in commercial projects, can use it as well.

r1308

Various minor CABAC optimizations

r1307

Fix bug in b-pyramid strict
Bug caused invalid streams in some situations.

r1306

Remove non-mod16 warning
Compression only "suffers" by an extremely marginal amount and too many people misinterpret the warning.

r1305

Fix two warnings + some minor optimizations

r1304

Fix a typo in b-pyramid help
And an errant space in common/macroblock.c

r1303

A bit more write-combining in macroblock_cache_load

r1302

split muxers.c into one file per format
simplify internal muxer API

r1301

Update fprofile with the latest change to b-pyramid

r1300

Fix assertion fail and incorrect costs with pyramid+VBV
Deal properly with QPfile'd B-refs.  x264 should handle multiple B-refs per minigop now, though only via forced frametypes.

x264 Revision Memo (13xx)

r1299

Improve CRF initial QP selection, fix get_qscale bug
If qcomp=1 (as in mb-tree), we don't need ABR_INIT_QP.
get_qscale could give slightly weird results with still images

r1298

Print more accurate error message if dump_yuv fails

r1297

Reduce memory usage of b-adapt 2 trellis
Also fix a minor bug where the algorithm ignored the last frame in the trellis.

r1296

Make B-pyramid spec-compliant
The rules of the specification with regard to picture buffering for pyramid coding are widely ignored.
x264's b-pyramid implementation, despite being practically identical to that proposed by the original paper, was technically not compliant.
Now it is.
Two modes are now available:
1) strict b-pyramid, while worse for compression, follows the rule mandated by Blu-ray (no P-frames can reference B-frames)
2) normal b-pyramid, which is like the old mode except fully compliant.
This patch also adds MMCO support (necessary for compliant pyramid in some cases).
MB-tree still doesn't support b-pyramid (but will soon).

r1295

Add missing free for nal_buffer
Fixes a memory leak.

r1294

sync yasm macros to ffmpeg

r1293

eliminate some divisions

r1292

Fix glitches with slow-firstpass + weightb + multiref + 2pass
Bug in r1277

r1291

Simplify some code in b-adapt 2's trellis

r1290

Fix a very rare integer overflow in slicetype analysis
Caused an assert failure when it occurred.
Bug is as old as adaptive B-frames.

r1289

Reduce the aggressiveness of 2-pass VBV
Now that B-frames are properly covered, we don't have to be as aggressive.
This eliminates some issues with skyrocketing QPs in B-frames in 2-pass VBV.

r1288

Fix regression: disable flash detection without B-frames

r1287

change all dct arrays to 1d.
the C standard doesn't allow you to iterate 1-dimensionally over 2d arrays, and nothing other than the dsp functions themselves cares about the 2dness of dct.
this fixes a miscompilation in x264_mb_optimize_chroma_dc.

r1286

Add row-based VBV for B-frames
While B-frames still aren't explicitly covered by ratecontrol, this should resolve issues of VBV underflows due to larger-than-expected B-frames.

r1285

Improve VBV, fix bug in 2-pass VBV introduced in MB-tree
Bug caused AQ'd row/frame costs to not be calculated (and thus caused underflows).
Also make VBV more aggressive with more threads in 2-pass mode.
Finally, --ratetol now affects VBV aggressiveness (higher is less aggressive).

r1284

Optimize exp2fix8
Slightly faster and more accurate rounding.

r1283

Avoid scenecuts in flashes and similar situations
"Flashes" are defined as any scene which lasts a very short period before a previous scene returns.
A common example of this is of course a camera flash.
Accordingly, look ahead during scenecut analysis and rule out the possibility of certain frames being scenecuts.
Also handles cases of tons of short scenes in sequence and avoids making those scenecuts as well.
Can only catch flashes of 1 frame in length with b-adapt 1.
With b-adapt 2, can catch flashes of length --bframes.
Speed cost should be negligible.

r1282

Fix bug where x264 generated non-compliant bitstreams with insane SAR values

r1281

rm msvc project files and related ifdefs

r1280

SSE4 version of 4x4 idct
27->24 clocks on Nehalem.
This is really just an excuse to use "movsd" in a real function.
Add some comments to subsum-related macros in x86util.

r1279

Constrained intra prediction support
Enable with --constrained-intra.  Significantly reduces compression, but required for the base layer of SVC encodes and maybe some other use-cases.

Commit sponsored by a media streaming company that wishes to remain anonymous.

r1278

Slightly improve non-RD p8x8 mode decision
Subpartition costs are effectively zero in CABAC if sub-8x8 search is off.

r1277

Reorder reference frames optimally on second pass
About +0.1-0.2% compression at normal bitrates, up to +1% at very low bitrates.
Only works if the first pass uses the same number of refs as the second (i.e. not with fast first pass).
Thus, only worthwhile at insanely slow speeds: as such, enable slow-firstpass by default with preset placebo.
Note that this changes the stats file format!

r1276

Fix typo in ratecontrol_summary

r1275

Clip log2_max_frame_num
It's still much higher than it needs to be, but that will be fixed with the upcoming MMCO patch.
Also make sure we don't write too large a frame_num or poc in slice header.

r1274

Fix some issues with 3-pass statsfile handling
The value of i_frame during encoder_close was incorrect.

r1273

Fix ctrl-C termation message with few frames encoded

r1272

Add support for single-frame VBV, improve compliance
This allows both constant-framesize and capped-framesize encoding.
Literal constant framesize isn't actually supported yet due to the lack of
filler support.
Example with 30fps video: --vbv-bufsize 200 --vbv-maxrate 6000 will ensure that
no frame is ever larger than 200 kilobits.

One example use-case of this is for zero-delay streaming where bandwidth costs
need to be minimized.  If every frame is smaller than 200 kilobits and the
client has a 6 megabit connection, every single frame can be instantly sent
to the client and handled without any decoder-side buffer.

Fix a mistake in VBV calculation--this may have caused the VBV to be slightly
non-compliant in some situations without x264 realizing it.
Add primitive prediction handling for rows with quantizers lower than their
reference.  This slightly improves VBV in CBR mode.
Various other minor improvements to VBV, mostly to make single-frame VBV work.

Commit sponsored by a media streaming company that wishes to remain anonymous.

r1271

Fix 10l in API change
frame_num was set to 1, not 0, for the first frame.  This broke spec compliance.
Didn't actually seem to cause any problems though except for breaking decoding on Quicktime.

r1270

Allow user-set FPS for inputs other than YUV

r1269

Improve threaded frame handling
Avoid unnecessary cond_wait

r1268

Attempt to detect miscompilation due to bug in gcc 4.2
I don't know if this bug still affects latest x264, but it can't hurt to try to detect it.
Accordingly refuse to open the encoder if detected.
Apparently VLC (on Windows) has been distributed for some time with a completely
broken x264 due to the use of a completely broken compiler (gcc 4.2).  In
particular, the MV costs seem to be calculated incorrectly on win32 when linking
from an application compiled without -ffast-math to an application with
-ffast-math.
I am not entirely certain why this occurs, but the result is, unsurprisingly,
encoding quality that makes MPEG-2 look good, due to the motion search being
completely broken.

r1267

Really fix encoder_close crash this time
Not-entirely-fixed in r1253.

r1266

Check for 16x16 partitions masquerading as smaller ones
Saves a few bits when using qpel-RD.

r1265

Update config.guess/sub; add Snow Leopard support

r1264

Fix integer overflow in 2-pass VBV
Bug caused slight undersizing in 2-pass mode in some cases.

r1263

Fix bug with various bizarre commandline combinations and mbtree
Second pass would have mbtree on even though the first pass didn't (and thus encoding would immediately fail).

r1262

Add intra prediction modes to output stats
Also eliminate some NANs in stat output with intra-only encoding.
Marginal speedup: disable stat calculation if log level is below X264_LOG_INFO.
Various minor cosmetics.

r1261

Overhaul syntax in muxers.c/matroska.c
The inconsistent syntax in these files has finally come to an end.

r1260

Major API change: encapsulate NALs within libx264
libx264 now returns NAL units instead of raw data.  x264_nal_encode is no longer a public function.
See x264.h for full documentation of changes.
New parameter: b_annexb, on by default.  If disabled, startcodes are replaced by sizes as in mp4.
x264's VBV now works on a NAL level, taking into account escape codes.
VBV will also take into account the bit cost of SPS/PPS, but only if b_repeat_headers is set.
Add an overhead tracking system to VBV to better predict the constant overhead of frames (headers, NALU overhead, etc).

r1259

Add missing fclose for mbtree input statsfile on second pass
Bug report by VFRmaniac

r1258

Improve progress indicator behavior
Progress indicator will now indicate based on output frame, not input frame.

r1257

Update yasm configure check
lzcnt apparently requires yasm 0.6.2.

r1256

Make MV costs global instead of static
Fixes some extremely rare threading race conditions and makes the code cleaner.
Downside: slightly higher memory usage when calling multiple encoders from the same application.

r1255

Don't print scenecut message multiple times in verbose mode
Occurred mostly with b-adapt 2.

r1254

Optimize rounding of luma and chroma DC coefficients
Reduce bitrate mostly-losslessly at low quantizers.
In some rare cases, bitrate reduction may be as high as 10%.
Luma rounding optimization (helps much less than chroma) requires trellis.

r1253

Fix crash if encoder_close is called before delayed frames are flushed
Also no longer flush frames when ctrl-Cing x264, so x264 will close faster.

r1252

Improve x264 help
Now has three help options: --help, --longhelp, and --fullhelp.
--help only shows the most basic options; most users should not need more than these.
Add usage examples.
Fix typo in a comment.

r1251

Factor out a redundant RD call in qpel-RD
Fixes a problem that was supposed to be, but didn't, get fully fixed in r1238.

r1250

Fix RD early-skip
Small quality improvement and speedup, was broken by r1214.

r1249

Faster CAVLC mb header writing for B macroblocks

r1248

Compile fixes for pre-ARMv6T2 and/or PIC

r1247

Change priority handling on some OSs
Instead of setting the lookahead thread to max priority, lower all the other threads' priorities instead.
This is particularly useful when the "max priority" is "realtime", as in Windows, which can cause some problems.

r1246

Threaded lookahead
Move lookahead into a separate thread, set to higher priority than the other threads, for optimal performance.
Reduces the amount that lookahead bottlenecks encoding, greatly increasing performance with lookahead-intensive settings (e.g. b-adapt 2) on many-core CPUs.
Buffer size can be controlled with --sync-lookahead, which defaults to auto (threads+bframes buffer size).
Note that this buffer is separate from the rc-lookahead value.
Note also that this does not split lookahead itself into multiple threads yet; this may be added in the future.
Additionally, split frames into "fdec" and "fenc" frame types and keep the two separate.
This split greatly reduces memory usage, which helps compensate for the larger lookahead size.
Extremely special thanks to Michael Kazmier and Alex Giladi of Avail Media, the original authors of this patch.

r1245

Force a link error in case of incompatible API
This is because the number of bug reports due to miscompiled ffmpeg builds is reaching critical mass.
The name of x264_encoder_open is now #defined based on the current X264_BUILD.
Note that this changes the calling convention required for dlopen, but not for ordinary calls to x264_encoder_open.

r1244

Get rid of "CBR" descriptor from qcomp
Though technically accurate in some vague way, I have never actually seen this
option used correctly, rather it has been used by hundreds of people who can't
read the documentation and believe that qcomp=0 is what should be used for CBR
encoding.

r1243

Faster me=tesa
But it still spends all too much time in me_search_ref rather than asm.

r1242

Multi-slice encoding support
Slicing support is available through three methods (which can be mixed):
--slices sets a number of slices per frame and ensures rectangular slices (required for Blu-ray).  Overridden by either of the following options:
--slice-max-mbs sets a maximum number of macroblocks per slice.
--slice-max-size sets a maximum slice size, in bytes (includes NAL overhead).
Implement macroblock re-encoding support to allow highly accurate slice size limitation.  Might be useful for other things in the future, too.

r1241

Fix a valgrind warning in b-adapt 2

r1240

fix asm symbols for oprofile (regression in r1221)

r1239

Fix bug in intra analysis in B-frames
i8x8/i4x4 never got analysed when fast_intra was toggled and RD was off; up to a 2-3% quality improvement in non-RD mode.
With this bug dating back to r369, this is probably the second-oldest bug ever fixed in x264.

r1238

Fix bug in b16x16 qpel RD
Incorrect cost was used to initialize the search.

r1237

Check minimum chroma QP in addition to luma QP during CQM init
Correctly error out if the implied minimum chroma QP is too low.
Add missing emms to checkasm macroblock_tree_propagate test.

r1236

Faster mbtree propagate and x264_log2, less memory usage
Avoid an int->float conversion with a small table.
Change lowres_inter_types to a bitfield; cut its size by 75%.
Somewhat lower memory usage with lots of bframes.
Make log2/exp2 tables global to avoid duplication.

r1235

Fix keyint=1 + VBV + rc-lookahead

r1234

Faster x264_exp2fix8
22->13 cycles on Core 2 with mfpmath=sse

r1233

compile x86 with fpmath=sse by default

r1232

ARM configure: enable NEON-related options by default
When compiling for ARM, x264 will compile by default for Cortex A8 unless specified otherwise.
To compile for pre-ARMv6, --disable-asm is required.

r1231

2-pass VBV fixes
Properly run slicetype frame cost with 2pass + MB-tree.
Slash the VBV rate tolerance in 2-pass mode; increasing it made sense for the highly reactive 1-pass VBV algorithm, but not for 2-pass.
2-pass's planned frame sizes are guaranteed to be reasonable, since they are based on a real first pass, while 1-pass's, based on lookahead SATD, cannot always be trusted.

r1230

prefetch, memcpy_aligned, memzero_aligned, avg, mc_luma, get_ref, mc_chroma, hpel_filter, frame_init_lowres

r1225

GSOC merge part 3: ARM NEON pixel assembly functions
SAD, SADX3/X4, SSD, SATD, SA8D, Hadamard_AC, VAR, VAR2, SSIM

r1224

GSOC merge part 2: ARM stack alignment
Neither GCC nor ARMCC support 16 byte stack alignment despite the fact that NEON loads require it.
These macros only work for arrays, but fortunately that covers almost all instances of stack alignment in x264.

r1223

Fix unaligned accesses in bitstream writer
Fixes x264 on CPUs with no unaligned access support (e.g. SPARC).
Improves performance marginally on CPUs with penalties for unaligned stores (e.g. some x86).

r1222

Fix bug in calculation of I-frame costs with AQ.

r1221

GSOC merge part 1: Framework for ARM assembly optimizations
x264 will detect which ARM core it's building for and only build NEON asm if the target is ARMv6 or above, then enable NEON at runtime.

r1220

Fix a bug in checkasm and two OSX fixes
MC chroma checkasm test could crash in some situations
Remove -lmx, as it's not needed and the iPhone doesn't have it.
Remove unused sqrtf emulation; it breaks if math.h is included.

r1219

Improve QPRD
Always check the last macroblock's QP, even if the normal search doesn't reach it.
Raise the failure threshold when moving towards the last macroblock's QP.
0.2-1% improved compression.

r1218

Fix MB-tree with keyint<3
Also slightly improve VBV keyint handling.

r1217

Fix bug in VBV lookahead + no MB-tree
I-frames need to have VBV lookahead run on them as well.

r1216

Add support for frame-accurate parameter changes
Parameter structs can now be passed with individual frames.
The previous method would only change the parameter of what was currently being encoded, which due to delay might be very far from an intended exact frame.
Also add support for changing aspect ratio.  Only works in a stream with repeating headers and requires the caller to force an IDR to ensure instant effect.

r1215

Fix x264_encoder_reconfig with multithreading
New behavior: reconfigging the encoder will result in changes being applied
to each of the encoding threads as they finish encoding the current frame.

r1214

Fix two bugs in QPRD
QPRD could in some cases force blocks to skip when they shouldn't be ~(+0.01db)
Force QPRD to abide by qpmin/qpmax restrictions.

r1213

Lookahead VBV
Use the large-scale lookahead capability introduced in MB-tree for ratecontrol purposes.
(Does not require MB-tree, however.)
Greatly improved quality and compliance in 1-pass VBV mode, especially in CBR; +2db OPSNR or more in some cases.
Fix some other bugs in VBV, which should improve non-lookahead mode as well.
Change the tolerance algorithm in row VBV to allow for more significant mispredictions when buffer is nearly full.
Note that due to the fixing of an extremely long-standing bug (>1 year), bitrates may change by nontrivial amounts in CRF without MB-tree.

r1212

Fix bug in b-adapt 1
B-adapt 1 didn't use more than MAX(1,bframes-1) B-frames when MB-tree was off.

r1211

Fix a potential failure in VBV
If VBV does underflow, ratecontrol could be permanently broken for the rest of the clip.
Revert part of the previous VBV changes to fix this.

r1210

new API function x264_encoder_delayed_frames.
fix x264cli on streams whose total length is less than the encoder latency.

r1209

Add no-mbtree to fprofile (and fix pyramid in fprofile)

r1208

Don't print a warning about direct=auto in 2pass when B-frames are off

r1207

fix lowres padding, which failed to extrapolate the right side for some resolutions.
fix a buffer overread in x264_mbtree_propagate_cost_sse2. no effect on actual behavior, only theoretical correctness.
fix x264_slicetype_frame_cost_recalculate on I-frames, which previously used all 0 mb costs.
shut up a valgrind warning in predict_8x8_filter_mmx.

r1206

simd part of x264_macroblock_tree_propagate.
1.6x faster on conroe.

r1205

MB-tree fixes:
AQ was applied inconsistently, with some AQed costs compared to other non-AQed costs. Strangely enough, fixing this increases SSIM on some sources but decreases it on others. More investigation needed.
Account for weighted bipred.
Reduce memory, increase precision, simplify, and early terminate.

r1204

Add missing free()s for new data allocated for MB-tree
Eliminates a memory leak.

r1203

Fix keyframe insertion with MB-tree and no B-frames

r1202

Fix MP4 output (bug in malloc checking patch)

r1201

Gracefully terminate in the case of a malloc failure
Fuzz tests show that all mallocs appear to be checked correctly now.

r1200

Fix a potential infinite loop in QPfile parsing on Windows
ftell doesn't seem to work properly on Windows in text mode.

2009-08-08T02:31:00.001+09:00

x264 Revision Memo (12xx)

r1199

Fix delay calculation with multiple threads
Delay frames for threading don't actually count as part of lookahead.

r1198

Add "veryslow" preset
Apparently some people are actually *using* placebo, so I've added this preset to bridge the gap.

r1197

Macroblock-tree ratecontrol
On by default; can be turned off with --no-mbtree.
Uses a large lookahead to track temporal propagation of data and weight quality accordingly.
Requires a very large separate statsfile (2 bytes per macroblock) in multi-pass mode.
Doesn't work with b-pyramid yet.
Note that MB-tree inherently measures quality different from the standard qcomp method, so bitrates produced by CRF may change somewhat.
This makes the "medium" preset a bit slower.  Accordingly, make "fast" slower as well, and introduce a new preset "faster" between "fast" and "veryfast".
All presets "fast" and above will have MB-tree on.
Add a new option, --rc-lookahead, to control the distance MB tree looks ahead to perform propagation analysis.
Default is 40; larger values will be slower and require more memory but give more accurate results.
This value will be used in the future to control ratecontrol lookahead (VBV).
Add a new option, --no-psy, to disable all psy optimizations that don't improve PSNR or SSIM.
This disables psy-RD/trellis, but also other more subtle internal psy optimizations that can't be controlled directly via external parameters.
Quality improvement from MB-tree is about 2-70% depending on content.
Strength of MB-tree adjustments can be tweaked using qcompress; higher values mean lower MB-tree strength.
Note that MB-tree may perform slightly suboptimally on fades; this will be fixed by weighted prediction, which is coming soon.

r1196

Various 1-pass VBV tweaks
Make predictors have an offset in addition to a multiplier.
This primarily fixes issues in sources with lots of extremely static scenes, such as anime and CGI.
We tried linear regressions, but they were very unreliable as predictors.
Also allow VBV to be slightly more aggressive in raising QPs to avoid not having enough bits left in some situations.
Up to 1db improvement on some clips.

r1195

Fix another 10L in QPRD
An entry in subpel_iterations was missing.
I have no idea how QPRD was working at all without this change.

r1194

Update help and cleanup in ratecontrol.c
Deal with some out-of-date information.

r1193

15% faster refine_bidir_satd, 10% faster refine_bidir_rd (or less with trellis=2)
re-roll a loop (saves 44KB code size, which is the cause of most of this speed gain)
don't re-mc mvs that haven't changed

r1192

Faster bidir_rd plus some bugfixes
Cache chroma MC during refine_bidir_rd and use both the luma and chroma caches to skip MC in macroblock_encode.
Fix incorrect call to rd_cost_part; refine_bidir_rd output was incorrect for i8>0.
Remove some redundant clips.
~12% faster refine_bidir_rd.

r1191

Add "fastdecode" tune option
It does what it says it does.

r1190

Fix two bugs in QPRD
fprofile settings now actually fprofile QPRD.
Don't use i_mbrd before initializing it.

r1189

Fix 10l in QPRD
Trellis used wrong lambda with trellis=1

r1188

Fix a nondeterminism with threads and subme>7
Also add a few more checks to eliminate the need for spel_border.

r1187

Add QPRD support as subme=10
Refactor trellis lambda selection to be done in analyse_init instead of in trellis.
This will allow for more easy adaption of lambda later on; for now it allows constant lambda across variable QPs.
QPRD is only available with adaptive quantization enabled and generally improves SSIM and visual quality.
Additionally, weight the SSD values from RD based on the relative QP offset for chroma; helps visually at high QPs where chroma has a lower QP than luma.
This fixes some visual artifacts created by QPRD at high QPs.
Note that this generally hurts PSNR and SSIM, and so is only on when psy-RD is on.

r1186

SSSE3 cachesplit workaround for avg2_w16
Palignr-based solution for the most commonly used qpel function.
1-1.5% faster overall on Core 2 chips.

r1185

shut up valgrind warnings in trellis

r1184

New AQ algorithm option
"Auto-variance" uses log(var)^2 instead of log(var) and attempts to adapt strength per-frame.
Generates significantly better SSIM; on by default with --tune ssim.
Whether it generates visually better quality is still up for debate.
Available as --aq-mode 2.

r1183

Cacheline-split SSSE3 chroma MC
~70% faster chroma MC on 32-bit Conroe
Also slightly faster SSSE3 intra_sad_8x8c

r1182

Improve documentation of qp/crf options

r1181

Merge array_non_zero into zigzag_sub
Faster lossless, cleaner code.
SSSE3 version of zigzag_sub_4x4_field, faster lossless interlaced coding.

r1180

Fix bug in reference frame autoadjustment
For some types of input file, x264 did the adjustment before width/height were known.

r1179

Fix fprofile settings to match changes in defaults
Also add b-adapt 2 to fprofile.

r1178

Slightly faster dequant_flat assembly
Eliminate some redundant shifts.

r1177

Totally new preset system for x264.c (not libx264), new defaults
Other new features include "tune" and "profile" settings; see --help for more details.
Unlike most other settings, "preset" and "tune" act before all other options.
However, "profile" acts afterwards, overriding all other options.
Our defaults have also changed: new defaults are --subme 7 --bframes 3 --8x8dct --no-psnr --no-ssim --threads auto --ref 3 --mixed-refs --trellis 1 --weightb --crf 23 --progress.
Users will hopefully find these changes to greatly improve usability.

r1176

Update Gabriel's email address in AUTHORS

r1175

Early termination for chroma encoding
Faster chroma encoding by terminating early if heuristics indicate that the block will be DC-only.
This works because the vast majority of inter chroma blocks have no coefficients at all, and those that do are almost always DC-only.
Add two new helper DSP functions for this: dct_dc_8x8 and var2_8x8.  mmx/sse2/ssse3 versions of each.
Early termination is disabled at very low QPs due to it not being useful there.
Performance increase is ~1-2% without trellis, up to 5-6% with trellis=2.
Increase is greater with lower bitrates.

r1174

Fix bug in checkasm
frame_init_lowres_core check didn't check the C plane.
However, all x86 and PPC assembly was correct regardless of the unit test being incorrect.

r1173

Add subpartition cost for sub-8x8 blocks
Improves sub-p8x8 mode decision.

r1172

Yet more CABAC and CAVLC optimizations
Also clean up a lot of pointless code duplication in CAVLC MV coding.

r1171

Various CABAC optimizations and cleanups
Faster CABAC CBF context calculation for inter blocks.
Add x264_constant_p(), will probably be useful in the future as well.
Simpler subpartition functions.
Clean up and optimize mvd_cpn a bit more.
Various other minor optimizations.

r1170

AltiVec version of frame_init_lowres_core. 22.4x faster than C on PPC7450 and 25x on PPC970MP.

r1169

MMX CABAC mvd sum calculation
Faster CABAC mvd coding.

r1168

Faster MV prediction
Smaller code size, plus I get to use goto.

r1167

Fix potential crash in checkasm
ssim_end4_sse2 requires aligned sums

r1166

SSSE3, faster SSE2/MMX integral_init4v
The real reason I wrote this was an excuse to use shufpd.

r1165

configure check for uclinux

r1164

fix a crash on frame width <= 48 pixels

r1163

configure check for cc, rather than reporting lack of compiler as an asm error.
configure check for -mno-cygwin, since it's removed from gcc4.

r1162

a better way to keep track of mv candidates.
2-4% faster dia, hex, and umh.

r1161

reorder some motion estimation patterns.
this change is useless on its own, but segregates the bitstream-changing part out of my next optimization.

r1160

Fix VBV warning broken in r915
x264 will now correctly warn about maxrate specified without bufsize even when a level is not set.

r1159

configure check for ssse3-capable binutils

r1158

Fix 10L in r1155
Broke --me esa/tesa due to forgetting to add handling for x264_cost_mv_fpel.

r1157

Fix bug where satd was incorrectly used with subme<=1
Faster subme<=1 with i4x4 enabled.

r1156

Remove some pointless error handling code in cabac/cavlc

r1155

Save some memory on mv cost arrays
Have quantizers that use the same lambda share the same cost array.

r1154

Various CABAC and CAVLC optimizations Backport CAVLC partial-inlining early termination to CABAC (~2-4% faster CABAC residual coding)

r1153

fix a race condition at the end of thread_input

r1152

Various trellis speed optimizations

r1151

Make i686 the default arch on x86_32
Disabling asm will default to a generic arch.
Also fix configure for gcc 4.4.

r1150

Faster signed golomb coding
3% faster CAVLC RDO and bitstream writing.

r1149

Faster spatial direct MV prediction
unroll/tweak col_zero_flag

r1148

More CABAC and CAVLC optimizations
Simplified function calling for block_residual_write_(cabac|cavlc) and improved sigmap coding.
Tried making 0/1-bit specific versions of CABAC asm, but benefit was minimal under GCC 4.3.
Helped a decent bit under 3.4, but you shouldn't be using such old versions anyways.

r1147

Various optimizations in frametype lookahead

r1146

Some cosmetics/cleanup
Move some macros to x86util.asm that should have been there to begin with.
Fix a typo that didn't cause any issues.

r1145

fix "incompatible types in initialization" compilation issues with GCC 4.3 (which is stricter than previous compiler version)

r1144

fix conversions between vectors with differing element types or numbers of subparts errors

r1143

Add "coded blocks" stat to output information.
This measures the total percentage of blocks, intra and inter, which have nonzero coefficients.
"y,uvAC,uvDC" refers to luma, chroma DC, and chroma AC blocks.
Note that skip blocks are included in this stat.

r1142

Enable asm predict_8x8_filter
I'm not entirely sure how this snuck its way out of holger's intra pred patch.

r1141

Remove various bits of dead code found by CLANG.

r1140

Slightly faster SSE4 SA8D, SSE4 Hadamard_AC, SSE2 SSIM
shufps is the most underrated SSE instruction on x86.

r1139

Various CABAC optimizations
Move calculation of b_intra out of the core residual loop and hardcode it where applicable.
Inlining cabac_mb_mvd was unnecessary and wasted tremendous amounts of code size.  Inlining only cache_mvd is faster and significantly smaller.

r1138

CAVLC optimizations
faster bs_write_te, port CABAC context selection optimization to CAVLC.

r1137

Faster CABAC RDO
Since the bypass case is quite unlikely, especially when doing merged sigmap/level coding,
it's faster to use a branch than a cmov.

r1136

Activate intra_sad_x3_8x8c in lookahead

r1135

MBAFF interlaced coding is not allowed in baseline profile

r1134

intra_sad_x3_8x8 assembly

r1133

intra_sad_x3_4x4 assembly

r1132

intra_sad_x3_8x8c assembly
Also fix intra_sad_x3_16x16's use of "n" as a loop variable (broke SWAP)

r1131

Shave one instruction off CABAC encode_decision
range_lps>>6 ranges from 4-7, so (range_lps>>6)-4 == (range_lps>>6) & 3

r1130

Faster probe_skip
Add a second chroma threshold after the DC transform.

r1129

Add missing "static" qualifier to two arrays
Should slightly improve performance.

r1128

SSE2 zigzag_interleave
Replace PHADD with FastShuffle (more accurate naming).
This flag represents asm functions that rely on fast SSE2 shuffle units, and thus are only faster on Phenom, Nehalem, and Penryn CPUs.

r1127

Faster integral_init
palignr to avoid unaligned loads is worth it in inith, but not initv.

r1126

Faster SSSE3 hpel_filter_v
~10% faster hpel_filter on 64-bit Penryn.
32-bit version by Jason Garrett-Glaser.

r1125

Faster SSE2 pixel_var
Optimized using the DEINTB method from r1122.  ~32% faster var_16x16 on Conroe.

r1124

SSSE3 hpel_filter_v
Optimized using the same method as in r1122.  Patch partially by Holger.
~8% faster hpel filter on 64-bit Nehalem

r1123

Update some asm copyright headers

r1122

Vastly faster SATD/SA8D/Hadamard_AC/SSD/DCT/IDCT
Heavily optimized for Core 2 and Nehalem, but performance should improve on all modern x86 CPUs.
16x16 SATD: +18% speed on K8(64bit), +22% on K10(32bit), +42% on Penryn(64bit), +44% on Nehalem(64bit), +50% on P4(32bit), +98% on Conroe(64bit)
Similar performance boosts in SATD-like functions (SA8D, hadamard_ac) and somewhat less in DCT/IDCT/SSD.
Overall performance boost is up to ~15% on 64-bit Conroe.

r1121

Update x264 copyright date

r1120

Remove pre-scenecut from fprofile commands as well
Also add psy-trellis to fprofile

r1119

Slightly faster 8x16 SAD on Penryn Core 2
Same as MMX 8x16 cacheline SAD, but calls SSE2 8x16 SAD in non-cacheline case.
Only Nehalem benefits from sizes smaller than 8x16, and Nehalem doesn't use cacheline functions, so no smaller versions are included.

r1118

Fix scenecut and VBV with videos of width/height <= 32
Also remove an unused variable

r1117

Remove non-pre scenecut
Add support for no-b-adapt + pre-scenecut (patch by BugMaster)
Pre-scenecut was generally better than regular scenecut in terms of accuracy and regular scenecut didn't work in threaded mode anyways.
Add no-scenecut option (scenecut=0 is now no scenecut; previously it was -1)
Fix an incorrect bias towards P-frames near scenecuts with B-adapt 2.
Simplify pre-scenecut code.

r1116

Add AltiVec version of hadamard_ac. 2.4x faster than the C version.
Note this this implementation is pretty naive and should be improved
by implementing what's discussed in this ML thread:
date: Mon, Feb 2, 2009 at 6:58 PM
subject: Re: [x264-devel] [PATCH] AltiVec implementation of hadamard_ac routines

r1115

Deblocking was very slightly incorrect with partitions=all.
Bug found by BugMaster.

r1114

r1105 introduced array overflow in cbp handling

r1113

Show FPS when importing a raw YUV file

r1112

Windows 64-bit support

r1109

Spare a vec_perm and a vec_mergeh though using a LUT of permutation vectors.

r1108

Promote chroma planes to 16 byte alignment.
This will allow simplifying vectors loads that can only load 16-bytes
aligned data (such as AltiVec).

r1107

Fix 10L in intra pred
Forgetting a %define resulted in SIGILL on 32-bit systems without SSE (e.g. Athlon XP).

r1106

Add decimation in i16x16 blocks
Up to +0.04db with CAVLC, generally a lot less with CABAC.

r1105

Much faster CABAC residual context selection
Up to ~17% faster CABAC RDO, ~36% faster intra-only CABAC RDO.
Up to 7% faster overall in extreme cases.

r1104

Faster coeff_last64 on 32-bit

ｒ1103

More intra pred asm optimizations
SSSE3 version of predict_8x8_hu
SSE2 version of predict_8x8c_p
SSSE3 versions of both planar prediction functions
Optimizations to predict_16x16_p_sse2
Some unnecessary REP_RETs -> RETs.
SSE2 version of predict_8x8_vr by Holger.
SSE2 version of predict_8x8_hd.
Don't compile MMX versions of some of the pred functions on x86_64.
Remove now-useless x86_64 C versions of 4x4 pred functions.
Rewrite some of the x86_64-only C functions in asm.

r1102

Speed-up mc_chroma_altivec by using vec_mladd cleverly, and unrolling.
Also put width == 2 variant in its own scalar function because it's faster
than a vectorized one.

r1101

Merging Holger's GSOC branch part 2: intra prediction
Assembly versions of most remaining 4x4 and 8x8 intra pred functions.
Assembly version of predict_8x8_filter.
A few other optimizations.
Primarily Core 2-optimized.

画像のICCプロファイルとJPEG最適化

2009-06-30T20:34:00.001+09:00

Firefox3.5から画像のICCプロファイルに対応したので、少し調べてみました
Is your system ICC Version 4 ready?
上記URLで自分のPC環境でのICCプロファイル対応度を調べた結果

Firefox3.5→v2 GBRとv2 Adobe RGBに対応
IE8.0→v2 Adobe RGBのみ対応
Opera9.64→v2 Adobe RGBのみ対応
Safari4.0→全対応
GoogleChrome→未導入なので不明

以上のような結果になりました

次にJPEGの最適化について、今まではJPG Cleanerというソフトで軽量化していたんですが
しかし今回の件で調べてるうちに、Exif情報とともにICCプロファイル情報も削除していたようで…orz
~~これを機に代替ソフトを探してcarmineというソフトに移行することにしました~~
こっちはハフマンテーブルの最適化とExif情報の削除のみなので、ICCプロファイル情報はそのまま残されるようです

追記
carmineはプログレッシブJPEGに対応してないので、一度ベースライン形式に変換する必要があり
いくつかソフトを試して実験しているうちに、XnViewという画像ビューワのメタデータ消去機能で十分という結果になりました／(^o^)＼
海外ソフトですが標準で日本語に対応していて、誤訳や未翻訳も目立ちません
削除する項目を選択できる上に、ハフマンテーブルの最適化も可能という＞＜
圧縮率はcarmineのほうが僅かにいいものの、殆ど気にならないレベルの差でした

先日からzoomeがHD動画に対応したようですが
再生するにはBitTorrent DNAとかいうアプリを入れなければいけないらしく
アプリを入れてないとHD動画は動画下部のリンクから飛んだ先でないと再生出来ない
導入する気の無い人には面倒なだけだし、常駐型P2Pとか入れたくもない

というわけでYoutube High Qualityを参考にzoomeのURLに?no_bt=1を追加して再読み込みするスクリプトを作成
（…といってもほとんどパクリですが）
一応Firefox 3.0.10で動作確認はしたものの、動画のない日記でも再読み込みしてしまう／(^o^)＼

x264 Revision Memo (10xx)

2009-02-03T14:22:00.001+09:00

x264 Revision Memo (11xx)

r1099

Faster 8x8dct+CAVLC interleave
Integrate array_non_zero with the CAVLC 8x8dct interleave function.
Roughly 1.5-2x faster than the original separate array_non_zero method.

r1098

Measure CBP cost in i8x8 RD refinement
~0.02-0.05db PSNR gain at high quants in intra-only encoding, pretty small otherwise.
Allows a small optimization in i8x8 encoding.

r1097

Take advantage of saturated signed horizontal sum instructions in
the variance computation epilogue since there won't be any overflow
triggering an overflow.
Suggested by Loren Merritt

r1096

Massive overhaul of nnz/cbp calculation
Modify quantization to also calculate array_non_zero.
PPC assembly changes by gpoirior.
New quant asm includes some small tweaks to quant and SSE4 versions using ptest for the array_non_zero.
Use this new feature of quant to merge nnz/cbp calculation directly with encoding and avoid many unnecessary calls to dequant/zigzag/decimate/etc.
Also add new i16x16 DC-only iDCT with asm.
Since intra encoding now directly calculates nnz, skip_intra now backs up nnz/cbp as well.
Output should be equivalent except when using p4x4+RDO because of a subtlety involving old nnz values lying around.
Performance increase in macroblock_encode: ~18% with dct-decimate, 30% without at CRF 25.
Overall performance increase 0-6% depending on encoding settings.

r1095

Add PowerPC support for "checkasm --bench", reading the time base register.
This isn't ideal since the `time base' register is running at a fraction
of the processor cycle speed, so the measurement isn't as precise as x86's
rdtsc.
It's better than nothing though...

r1094

fix detection of pthread and isfinite on OpenBSD

r1093

remove $ECHON kludge, which broke on SunOS. bring back `gcc -MT`.
remove auto-reconfigure on svn update, which has done nothing since we stopped using svn.
fix $AS on sparc (was disabled by mmx check).
fix --extra-asflags (was ignored).
mark bash scripts as bash, not sh

patch partly by Greg Robinson and Jugdish.

r1092

1.6x faster satd_c (and sa8d and hadamard_ac) with pseudo-simd.
60KB smaller binary.

r1091

Hack around a potential failure point in VBV
pred_b_from_p can become absurdly large in static scenes, leading to rare collapses of quality with VBV+B-frames+threads.
This isn't a final fix, but should resolve the problem in most cases in the meantime.

r1090

Much faster chroma encoding and other opts
~15% faster chroma encode by reorganizing CBP calculation and adding special-case idct_dc function, since most coded chroma blocks are DC-only.
Small optimization in cache_save (skip_bp)
Fix array_non_zero to not violate strict aliasing (should eliminate miscompilation issues in the future)
Add in automatic substitutions for some asm instructions that have an equivalent smaller representation.

r1089

add AltiVec implementation of x264_mc_copy_w16_aligned

r1088

add AltiVec implementation of x264_pixel_var_16x16 and x264_pixel_var_8x8

r1087

add AltiVec 16 <-> 32 bits conversions macros

r1086

Replace 16x16=>32 mul + pack + add by a simple 16x16=>16 multiply-add.
Suggested by Loren.

r1085

Eliminate support for direct_8x8_inference=0
The benefit in the most extreme contrived situation was at most 0.001db PSNR, at the cost of slower decoding.
As this option was basically useless, it was a waste of code and prevented some other useful optimizations.
Remove some unused mc code related to sub-8x8 partitions.
Small deblocking speedup when p4x4 is used.
Also remove unused x264_nal_decode prototype from x264.h.

ｒ1084

Add AltiVec and CPU numbers detection on OpenBSD.

r1083

Add AltiVec implementation of predict_8x8c_p. 2.6x faster than scalar C.

r1082

Warn if direct auto wasn't set on the first pass
And, if it wasn't, run direct auto as if it was the first pass, rather than simply forcing temporal direct mode on all frames.
Also a small tweak to coeff_level_run asm.

r1081

Changes the PowerPC ppccommon.h header so it no longer checks for a particular
OS such as Linux but instead looks for HAVE_ALTIVEC_H being set.
Fixes all *BSD/PowerPC builds.

r1080

update x264_hpel_filter_altivec's prototype to match the one of the C version.
It changed in commit 045ae4045a1827555b3eaab4fbf3c9809e98c58f (factorization of mallocs)
(NB: Altivec implementation wasn't allocating and writing to any scratch memory.)

r1079

rename vector+array unions to closer match the vector typedefs names.

r1078

Add Altivec implementation of all the remaining 16x16 predict routines.

r1077

Cache ref costs and use more accurate MV costs
New MV costs should improve quality slightly by improving the smoothness of the field of MV costs (and they're closer to CABAC's actual costs).
Despite being optimized for CABAC, they still help under CAVLC, albeit less.
MV cost change by Loren Merritt

r1076

Support forced frametypes with scenecut/b-adapt
This allows an input qpfile to be used to force I-frames, for example.
The same can be done through the library interface.
Document the format of the qpfile in --longhelp and the forcing of frametypes in x264.h
Note that forcing B-frames and B-refs may not always have the intended result.
Patch partially by Steven Walters .

r1075

Remove an IDIV from i8x8 analysis
Only one IDIV is left in macroblock level code (transform_rd)

r1074

Fix regression in r1066
With some combinations of video width and other settings, the scratch buffer was slightly too small.
This caused heap corruption on some systems.
Also prevent merange from being raised during encoding with esa/tesa through encoder_reconfig, as this no longer works.

r1073

Disable B-frames in lossless mode
They hurt compression anyways, and direct auto was bugged with lossless.

r1072

Factorize in ppccommon.h the conditional inclusion of altivec.h on Linux systems.

r1071

Disable __builtin_clz() intrinsic on gcc versions prior to 3.4.
The function did not exist before that version.

r1070

Small tweaks to coeff asm
Factor out a few redundant pxors
Related cosmetics

r1069

Use the correct strtok under MSVC
Also change one malloc -> x264_malloc

r1068

Add stack alignment for lookahead functions
Should allow libx264 to be called from non-gcc-compiled applications without adding force_align_arg_pointer.

r1067

Add support for SSE4a (Phenom) LZCNT instruction
Significantly speeds up coeff_last and coeff_level_run on Phenom CPUs for faster CAVLC and CABAC.
Also a small tweak to coeff_level_run asm.

r1066

factor mallocs out of hpel, ssim, and esa.
there should now be no memory allocation outside of init-time.

r1065

Much faster CAVLC RDO and bitstream writing
Pure asm version of level/run coding.  Over 2x faster than C.
Up to 40% faster CAVLC RDO.  Overall benefit up to ~7.5% with RDO or ~5% with fast encoding settings.

r1064

Cosmetics: cleaner syntax for defining temporary registers in asm
Globally define t#[qdwb], so that only t# needs to be locally defined when reorganizing registers

r1063

Much faster CABAC RDO
Since RDO doesn't care about what order bit costs are calculated, merge sigmap and level coding into the same loop in RDO.
This is bit-exact for 4x4dct but slightly incorrect for 8x8dct due to the sigmap containing duplicated contexts.
However, the PSNR penalty of this is extremely small (~0.001db).
Speed benefit is about 15% in 4x4dct and 30% in 8x8dct residual bit cost calculation at QP20.
Overall encoding speed benefit is up to 5%, depending on encoding settings.
Also remove an old unnecessary CABAC table that hasn't been used for years.

r1062

VLC table optimizations
Slightly reorganize VLC tables for ~2% faster block_residual_write_cavlc.
Also a small optimization in p8x8 CAVLC.

ｒ1061

Fix crash in --me esa/tesa introduced in r1058
Also suppress the last mingw warning message

r1060

Optimize variance asm + minor changes
Remove SAD argument from var, not needed anymore.
Speed up var asm a bit by eliminating psadbw and instead HADDWing at end.
Eliminate all remaining warnings on gcc 3.4 on cygwin
Port another minor optimization from lavc (pskip)

r1059

Minor CABAC cleanups and related optimizations
Merge the two list tables to allow cleaner MC/CABAC/CAVLC code
Remove lots of unnecessary {s
Port some very minor opts from lavc

r1058

faster ESA init
reduce memory if using ESA and not p4x4

r1057

More macroblock_cache optimizations
Patch partially by Loren Merritt

r1056

Faster macroblock_cache_rect
Explicit loop unrolling

r1055

Optimizations in predict_mv_direct
Add some early terminations and minor optimizations
This change may also fix the extremely rare direct+threading MV bug.

r1054

Fix visual corruption when picture width was not mod 32.
The previous Altivec implemention of mc_chroma assumed that i_src_stride was always mod 16.

r1053

Add support for FSF GCC version >= 4.3 on OSX.
So far, only Apple GCC version was supported.

r1052

More accurate refcost for p8x8 CAVLC
Slightly better quality, especially in non-RD mode, with CAVLC.

r1051

use lookup tables instead of actual exp/pow for AQ
Significant speed boost, especially on CPUs with atrociously slow floating point units (e.g. Pentium 4 saves 800 clocks per MB with this change).
Add x264_clz function as part of the LUT system: this may be useful later.
Note this changes output somewhat as the numbers from the lookup table are not exact.

r1050

Suppress saveptr warnings on Windows GCC

r1049

More small speed tweaks to macroblock.c

r1048

Much faster CAVLC residual coding
Use a VLC table for common levelcodes instead of constructing them on-the-spot
Branchless version of i_trailing calculation (2x faster on Nehalem)
Completely remove array_non_zero_count and instead use the count calculated in level/run coding.  Note: this slightly changes output with subme > 7 due to different nonzero counts being stored during qpel RD.

r1047

fix compilation with GCC-4.3+

r1046

High Profile allows 25% higher maxbitrate/cpb
Correct level detection to take this into account.

r1045

s/nasm/yasm in VS project file

r1044

Cosmetic: update various file headers.

r1043

add date and compiler to `x264 --version`

r1042

10L in r1041

r1041

Significantly faster CABAC and CAVLC residual coding and bit cost calculation
Early-terminate in residual writing using stored nnz counts
To allow the above, store nnz counts for luma and chroma DC
Add assembly functions to find the last nonzero coefficient in a block
Overall ~1.9% faster at subme9+8x8dct+qp25 with CAVLC, ~0.7% faster with CABAC
Note this changes output slightly with CABAC RDO because it requires always storing correct nnz values during RDO, which wasn't done before in cases it wasn't useful.
CAVLC output should be equivalent.

r1040

dequant_4x4_dc assembly
About 3.5x faster DC dequant on Conroe

r1039

fix an overflow in dct4x4dc_mmx
(unlikely to have occurred in any real video)

r1038

Remove nasm support
Nasm won't correctly parse the SSE4 code introduced a few revisions ago, so we're removing support.
Users should upgrade to yasm 0.6.1 or later.

r1037

Fix rare warning messages in ratecontrol due to r1020

r1036

Fix MSVC compilation and clean up MSVC build file
Remove Release64 which never worked anyways.

r1035

Faster width4 SSD+SATD, SSE4 optimizations
Do satd 4x8 by transposing the two blocks' positions and running satd 8x4.
Use pinsrd (SSE4) for faster width4 SSD
Globally replace movlhps with punpcklqdq (it seems to be faster on Conroe)
Move mask_misalign declaration to cpu.h to avoid warning in encoder.c.
These optimizations help on Nehalem, Phenom, and Penryn CPUs.

r1034

fix indentation, whitespace cleanup, more consistent indentation of macro backslashes

r1033

Change some macros to be more sensitive to memory alignment, thus avoiding
useless loads/stores and calculations of permutation vectors.
Affected functions are all of mc_luma, mc_chroma, 'get_ref', SATD, SA8D and deblock.
Gains globally vary from ~5% - 15% on a depending on settings running on a 1.42 ghz G4.

r1032

refactor satd. 20KB smaller binary.
refactor sa8d. slightly faster.
more checkasm for hadamard.

r1031

Fix crash with threads and SSEMisalign on Phenom
Misalign mask needed to be set separately for each encoding thread.

r1030

Phenom CPU optimizations
Faster hpel_filter by using unaligned loads instead of emulated PALIGNR
Faster hpel_filter on 64-bit by using the 32-bit version (the cost of emulated PALIGNR is high enough that the savings from caching intermediate values is not worth it).
Add support for misaligned_mask on Phenom: ~2% faster hpel_filter, ~4% faster width16 multisad, 7% faster width20 get_ref.
Replace width12 mmx with width16 sse on Phenom and Nehalem: 32% faster width12 get_ref on Phenom.
Merge cpu-32.asm and cpu-64.asm
Thanks to Easy123 for contributing a Phenom box for a weekend so I could write these optimizations.

r1029

A few tweaks to decimate asm
A little bit faster on both 32-bit and 64-bit

r1028

Nehalem optimization part 2: SSE2 width-8 SAD
Helps a bit on Phenom as well
~25% faster width8 multiSAD on Nehalem

r1027

Add subme=0 (fullpel motion estimation only)
Only for experimental purposes and ultra-fast encoding.  Probably not a good idea for firstpass.

r1026

Fix minor memory leak in r1022

r1025

r1024 borked checkasm
Remove idct/dct2x2 from checkasm as they are no longer in dctf

r1024

Faster chroma encoding
9-12% faster chroma encode.
Move all functions for handling chroma DC that don't have assembly versions to macroblock.c and inline them, along with a few other tweaks.

r1023

Various cosmetics and minor fixes
Disable hadamard_ac sse2/ssse3 under stack_mod4
Fix one MSVC compilation warning
Fix compilation in debug mode in certain cases on x64
Remove eval.c from MSVC project
Fix crash when VBV is used in CQP mode
Patches by MasterNobody

r1022

Faster b-adapt + adaptive quantization
Factor out pow to be only called once per macroblock.  Speeds up b-adapt, especially b-adapt 2, considerably.
Speed boost is as high as 24% with b-adapt 2 + b-frames 16.

r1021

Faster CABAC residual encoding
6% faster block_residual_write_cabac in RD mode.

r1020

Fix potential crash in the case that the input statsfile is too short
Also resolve various other potential weirdness (such as multiple copies of the same error message in threaded mode).

r1019

Initial Nehalem CPU optimizations
movaps/movups are no longer equivalent to their integer equivalents on the Nehalem, so that substitution is removed.
Nehalem has a much lower cacheline split penalty than previous Intel CPUs, so cacheline workarounds are no longer necessary.
Thanks to Intel for providing Avail Media with the pre-release Nehalem CPU needed to prepare these (and other not-yet-committed) optimizations.
Overall speed improvement with Nehalem vs Penryn at the same clock speed is around 40%.

r1018

Fix potential infinite loop in VBV under GCC 4.2

r1017

Encoder_reconfig: esa/tesa can only be enabled if they were on to begin with
Bug report by kemuri-_9.

r1016

Fix bug in hadamard_ac SSE assembly
Some extreme inputs could cause overflows.

r1015

Full sub8x8 RD mode decision
Small speed penalty with p4x4 enabled, but significant quality gain at subme >= 6
As before, gain is proportional to the amount of p4x4 actually useful in a given input at the given bitrate.

r1014

Optimize CABAC bit cost calculation
Speed up cabac mvd and add new precalculated transition/entropy table.
Add "noup" function for cabac operations to not update the state table when it isn't necessary.
1-3% faster macroblock_size_cabac.
Cosmetics

r1013

Replace "git-command" with "git command" in version.sh for git 1.6 support

r1012

Add assembly version of CAVLC 8x8dct interleave
Faster CAVLC encoding and RDO with 8x8dct

r1011

Add support for psy-rd/trellis to encoder_reconfig

r1010

Fix Darwin speed regression

r1009

Further improve prediction of bitrate and VBV in threaded mode

r1008

Sub-8x8 Qpel-RD in P-frames
Improves quality when using p8x4/p4x8/p4x4 subpartitions
Benefit is proportional to how many sub-8x8 partitions are used; helps most at high bitrates and low resolutions.

r1007

Faster qpel-RD
3-4% faster qpel-RD; avoid re-checking bmv/pmv during the hex search.

r1006

Some minor optimizations in RD refinement
Don't write b subpartition in CABAC RDO
Calculate nonzero count in i4x4 CAVLC RDO

r1005

Faster deblocking when p4x4 isn't used Most of the MV checks can be skipped, resulting in faster strength calculation

r1004

Print profile and level information upon starting encode
Previously level was only printed as part of autodetect, and only in verbose mode.

r1003

Fix possible crash in trellis at very low QPs

r1002

Add assembly versions of decimate_score
3-7x faster decimation, 1-3% faster overall

r1001

Fix typo in subme8/9 lossless qpel-RD
Slightly improves compression.

r1000

Extend trellis to support luma/chroma DC and chroma AC
Small speed loss in trellis 1, slightly larger in trellis 2, but significant quality improvement.

x264 r1051

2008-12-12T13:55:00.001+09:00

r1051でAQ関連の変更があったようです

オリジナルとOreAQビルド使用者は特に気にしなくていいようですが
MixAQビルド使用者は--aq-sensitivityが従来と異なるので注意が必要とのこと

AQ内数学関数（logやexpなど）のルックアップテーブル化（いわゆる高速化）に伴い、
--aq-sensitivityの影響度合いが変わります。
今までとほぼ同じ結果を出すためには、「10 - ((10-(あなたのsensitivity)) * 1.5) 」を
新しい --aq-sensitivity にしてください。

某掲示板をみて、readmeに書いていた計算式が間違っていたことに気づくorz
えーっと、10を起点として、そこからの差分を1.5倍にすると今までと同じになります。
例：1051より前に、--aq-sensitivity 8 としていた人は、10-(10-8)*1.5 = 7 ということで、
1051では --aq-sensitivity 7 と設定すればよいです。

VFR maniac氏のMixAQビルドで--aq-mode 2以上の使用者も気にしなくていいのかな？
~~ちなみに--aq2-sensitivityも影響するのかどうかはまだよく分かりません…~~

UtVideo v5.0.0

2008-11-16T07:19:00.003+09:00

[UtVideo] バージョン 5.0.0

UtVideoのYV12対応版(ULY0)ｷﾀ━(ﾟ∀ﾟ)━!

早速現在使っているLagarith v1.3.19と比較した結果
圧縮率はLagarithには及ばないものの、圧縮／展開速度はUtVideoでした（実写ソース）
しかしULY0の映像をVDMやAviUtlで開こうとしてもエラーが出てしまう
（AviSynthで読み込んで渡すといけたのでVfWとかの問題なんでしょうか？）

uNicAudio.dll v2.0.3

2008-11-15T17:03:00.001+09:00

NicAudio 2.0.2 in CodePlex project - Doom9's Forum

NicAudioの新Ver？のようなベータ版のようなものが出ていました

変更点

2008/10/30 Tebasuna 2.0.3

First version from the same NicAudio.dll version. Differences with NicAudio:

- A unique function call instead 5 different.
- The bool param in NicMPG123Source now is int. The last parameter order in RAW/LPCM was changed.
- Now we can detect mp3, ac3 (VirtualDub) and dts (dtswav) in wav container and use the appropriate decoder.

Warning: WAV is a container and other compressed formats aren't supported. If you have this error:
UnicSource: Unssuported header format xxxx
try opening the file with the standard WavSource()

AC3 in mp4

2008-11-11T11:34:00.007+09:00

Kurtnoise氏のMP4BoxでAC3をmp4に格納出来るようになったわけですが
氏が改造したGabest版のMP4 Splitterを使ってみた結果

WMP　→　ちゃんと音声も聞こえて正常（Gabest版だから音ズレしてるけど）
MPC-HC　→　何故かHaali Media Splitterが強制的に使用されて音声聞こえない
VLC　→　5.1chの音声を2スピーカで聞くと右寄りに聞こえる（mkvだと問題無し）

それからMediaInfoで見てみると5.1chが2chに誤認識されてる模様
まぁ…自分の環境特有の問題なのかもしれない／(^o^)＼

追記
MediaInfo v0.7.7.8にてmp4のAC3のch数が正常に認識されるようになりました

x264 Revision Memo (9xx)

2008-10-03T12:22:00.001+09:00

x264 Revision Memo (10xx)

r999

rm gtk, avc2avi.
I don't remember why I allowed a gui into the repository in the first place. There's nothing that makes this one special relative to all the other x264 guis.
avc2avi doesn't compile since we removed the bitstream reader. And avc doesn't belong in avi.

r998

Resolve quality regression in r996
Accidentally removed the wrong line of code. I think this classifies as a "10l".
Thanks to techouse for initial bug report and skystrife for helping me find it.

r997

Fix minor memory leak accidentally added with the addition of b-adapt 2

r996

Rework subme system, add RD refinement in B-frames
The new system is as follows: subme6 is RD in I/P frames, subme7 is RD in all frames, subme8 is RD refinement in I/P frames, and subme9 is RD refinement in all frames.
subme6 == old subme6, subme7 == old subme6+brdo, subme8 == old subme7+brdo, subme9 == no equivalent
--b-rdo has, accordingly, been removed. --bime has also been removed, and instead enabled automatically at subme >= 5.
RD refinement in B-frames (subme9) includes both qpel-RD and an RD version of bime.

r995

Fix potential miscompilation of some inline asm
Caused problems under some gcc 4.x versions with predictive lossless

r994

Replace High 4:4:4 profile lossless with High 4:4:4 Predictive.
This improves lossless compression by about 4-25% depending on source.
The benefit is generally higher for intra-only compression.
Also add support for 8x8dct and i8x8 blocks in lossless mode; this improves compression very slightly.
In some rare cases 8x8dct can hurt compression in lossless mode, but its usually helpful, albeit marginally.
Note that 8x8dct is only available with CABAC as it is never useful with CAVLC.
High 4:4:4 Predictive replaced the previous profile in a 2007 revision to the H.264 standard.
The only known compliant decoder for this profile is the latest version of CoreAVC.
As I write this, JM does not actually correctly decode this profile.
Hopefully this lack of support will soon change with this commit, as x264 will be (to my knowledge) the first compliant encoder.

r993

Fix typo in progress indicator when using piped input

r992

avg_weight_ssse3

r991

fix bitstream writer on bigendian 64bit (regression in r903)

r990

remove authors whose code no longer exists

r989

more diagnostics when configure finds an unsuitable assembler

r988

Make x264 progress indicator more concise
Now the % indicator should be readable on the header of a minimized window on Windows systems.

r987

Fix deblocking + threads + AQ bug
At low QPs, with threads and deblocking on, deblocking could be improperly disabled.
Revision in which this bug was introduced is unknown; it may be as old as b_variable_qp in x264 itself.

r986

Resolve possible crash in bime, improve the fix in r985

r985

Fix rare crash issue in b-adapt
Regression *probably* in r979

r984

Merging Holger's GSOC branch part 1: hpel_filter speedups

r983

r980 borked weighted bime

r982

Disable I_PCM with psy-RD
psy-RD seems to put the PCM threshold a bit lower than it should be, so PCM is now disabled under psy-RD.

r981

Merge avg and avg_weight
avg_weight no longer has to be special-cased in the code; faster weightb

r980

Rewrite avg/avg_weight to take two source pointers
This allows the use of get_ref instead of mc_luma almost everywhere for bipred

r979

Use low-resolution lookahead motion vectors as an extra predictor
Improves quality considerably (0-5%) in 1pass/CRF mode, especially with lower --me values and complex motion.
Reverses the order of lowres lookahead search to improve the usefulness of the extra predictors.

r978

Add missing free() for f_qp_offset in frame.c

r977

Correct misprediction of bitrate in threaded mode
Improves bitrate accuracy in cases with large numbers of threads.
Loosely based on a patch by BugMaster.

r976

Fix a case in which VBV underflows can occur
Fix a potential case where a frame might be initially allocated too low a QP, which would then have to be raised a low during row-based ratecontrol.
In some cases, this could even produce VBV underflows in 2pass mode.

r975

Use correct format specifier for uint64_t

r974

Cache motion vectors in lowres lookahead
This vastly speeds up b-adapt 2, especially at large bframes values.
This changes output because now MV prediction in lookahead only uses L0/L1 MVs, not bidir. This isn't a problem, since the bidir prediction wasn't really correct to begin with, so the change in output is neither positive nor negative.
This also allowed the removal of some unnecessary memsets, which should also give a small speed boost.
Finally, this allows the use of the lowres motion vectors for predictors in some future patch.

r973

Fix regression in b-adapt patch: encoder_open failed for multipass encodes without bframes.

r972

Stop SAR in y4m input from overriding --sar on commandline

r971

hadamard_ac for psy-rd
c version is 1.7x faster than satd+sa8d+sad
ssse3 version is 2.3x faster than satd+sa8d+sad

r970

Psychovisually optimized rate-distortion optimization and trellis
The latter, psy-trellis, is disabled by default and is reserved as experimental; your mileage may vary.
Default subme is raised to 6 so that psy RD is on by default.

r969

Add optional more optimal B-frame decision method
This method (--b-adapt 2) uses a Viterbi algorithm somewhat similar to that used in trellis quantization.
Note that it is not fully optimized and is very slow with large --bframes values.
It also takes into account weightb, which should improve fade detection.
Additionally, changes were made to cache lowres intra results for each frame to avoid recalculating them. This should improve performance in both B-frame decision methods.
This can also be done for motion vectors, which will dramatically improve b-adapt 2 performance when it is complete.
This patch also reads b_adapt and scenecut settings from the first pass so that the x264 header information in the output file will have correct information (since frametype decision is only done on the first pass).

r968

Move adaptive quantization to before ratecontrol, eliminate qcomp bias
This change improves VBV accuracy and improves bit distribution in CRF and 2pass.
Instead of being applied after ratecontrol, AQ becomes part of the complexity measure that ratecontrol uses.
This allows for modularity for changes to AQ; a new AQ algorithm can be introduced simply by introducing a new aq_mode and a corresponding if in adaptive_quant_frame.
This also allows quantizer field smoothing, since quantizers are calculated beofrehand rather during encoding.
Since there is no more reason for it, aq_mode 1 is removed. The new mode 1 is in a sense a merger of the old modes 1 and 2.
WARNING: This change redefines CRF when using AQ, so output bitrate for a given CRF may be significantly different from before this change!

r967

Fix crash when using b-adapt at resolutions 32x32 or below.
Original patch by BugMaster, but was mostly rewritten in order to make b-adapt actually *work* at such resolutions, not merely stop crashing.

r966

Add title-bar progress indicator under WIN32
Also add bitrate-so-far output when piping data to x264 (total frames not known)
Patch mostly by recover from Doom9.

r965

Revert part of r963
In some rare (but significant) cases, the optimized nal_encode algorithm gave incorrect results.

r964

Predict 4x4_DC asm
Also remove 5-year-old unnecessary #define that reduced speed unnecessarily under MSVC-compiled builds

r963

Faster NAL unit encoding and remove unused nal_decode
Small speedup at very high bitrates

r962

CAVLC cleanup and optimizations
Also move some small functions in macroblock.c to a .h file so they can be inlined.

r961

Faster avg_weight assembly
Unrolling the loop a bit improves performance

r960

Faster H asm intra prediction functions
Take advantage of the H prediction method invented for merged intra SAD and apply it to regular prediction, too.

r959

Add merged SAD for i16x16 analysis
Roughly 30% faster i16x16 analysis under subme=1

r958

Add sad_aligned for faster subme=1 mbcmp
Distinguish between unaligned and aligned uses of mbcmp
SAD_aligned, for MMX SADs, uses non-cacheline SADs.

r957

Improve progress indicator
Show average bitrate so far during encoding
Decrease update interval for longer encodes (max of 10 frames encoded between updates)

r956

Fix speed regression in r951
Row SATDs are only necessary in VBV mode, so don't need to be checked if VBV is off.

r955

zigzag asm

r954

fix SOFLAGS used when building gtk frontend
patch by Markus Kanet %darkvision A gmx P eu%

r953

remove the distinction between itex and ptex

r951

Fix some uses of uninitialized row_satd values in VBV
Resolves some issues with QP51 in I-frames with scenecut

r950

Activate trellis in p8x8 qpel RD
Also clean up macroblock.c with some refactoring
Note that this change significantly reduces subme7+trellis2 performance, but improves quality.
Issue originally reported by Alex_W.

r949

Improve VBV accuracy
Don't use the previous frame's row SATD as a predictor if it is too different from this frame's row SATD.

r948

improve generation of Darwin libraries
Patch by vmrsss %vmrsss A gmail P com%

r947

Fix compilation in gcc 3.4.x (issue in r946)
Due to a bug in gcc 3.4.x, in certain cases of inlining, the array_non_zero_int_mmx inline asssembly is miscompiled and causes a crash with --subme 7 --8x8dct.
This minor hack fixes this issue.

r946

shut up various gcc warnings

r945

fix a crash with invalid args and --thread-input (introduced in r921)

r944

drop support for x86_32 PIC.

r943

use permute macros in satd
move some more shared macros to x264util.asm

r942

r941

r940 broke threads

r940

Early termination for bS=0, alpha=0, beta=0
Refactoring, various other optimizations
About 30% faster deblocking overall.

r934

r933

yet another posix-emulating define on solaris

r932

update msvc projectfile

r931

drop support for msvc6

r930

Prevent VBV from lowering quantizer too much
This code seemed to act up unexpectedly sometimes, creating a situation where in 1-pass VBV mode, a frame's quantizer would drop all the way to qpmin and then shoot back upwards to qpmax, causing serious visual issues.
This change may decrease bitrate in VBV mode, but that is preferable to the artifacting produced by this code.

r929

Improve subme7 at low QPs and add subme7 support in lossless mode

r928

cosmetics: merge x86inc*.asm

r927

Add missing x264util.asm

r926

Basic sanity checking of qpmax/qpmin options

r925

Fix regression in r922
set the chroma DC coefficients to zero for residual coding in qpel-rd

r924

Refactor asm macros part 2: DCT

r923

Refactor asm macros part 1: DCT

r922

Improve intra RD refine, speed up residual_write_cabac
a do/while loop can be used for residual_write, but i8x8 had to be fixed so that it wouldn't call residual_write with zero coeffs
proper nnz handling added to cabac intra rd refine
chroma cbp added to 8x8 chroma rd
cbp was tested, but wasn't useful

r921

Fix a few more minor memleaks

r920

stats summary: print distribution of numbers of consecutive B-frames

r919

add interlacing to the list of stuff checked by x264_validate_levels

r918

Fix C99-ism in r907

r917

Faster temporal predictor calculation
Split into a separate commit because this changes rounding, and thus changes output slightly.

r916

Align lowres planes for improved cacheline split performance

r915

autodetect level based on resolution/bitrate/refs/etc, rather than defaulting to L5.1
if vbv is not enabled (and especially in crf/cqp), we have to guess max bitrate, so we might underestimate the required level.

r914

fix bs_write_ue_big for values >= 0x10000.
(no immediate effect, since nothing writes such values yet)

r913

Fix lossless mode borked in r901

r912

Relax QPfile restrictions
Allow a QPfile to contain fewer frames than the total number of frames in the video and have ratecontrol fill in the rest.
Patch by kemuri9.

r911

Limit MVrange correctly in interlaced mode
Bug report by Sigma Designs, Inc.

r910

Fix bug with PCM and adaptive quantization
In rare cases CABAC desync could occur, causing bitstream corruption

r909

Fix memory leak upon x264 closing
Doesn't affect the CLI, but potentially important for programs which call x264 as a shared library.

r908

Fix compilation on PPC systems (borked in r903)
Bigendian systems didn't have endian_fix32 defined

r907

Add L1 reflist and B macroblock types to x264 info
Also remove display of "PCM" if PCM mode is never used in the encode.
L1 reflist information will only show if pyramid coding is used.

r906

Fix and enable I_PCM macroblock support
In RD mode, always consider PCM as a macroblock mode possibility
Fix bitstream writing for PCM blocks in CAVLC and CABAC, and a few other minor changes to make PCM work.
PCM macroblocks improve compression at very low QPs (1-5) and in lossless mode.

r905

de-duplicate vlc tables

r904

faster ue/se/te write

r903

faster bs_write

r902

cosmetics in ssd asm

r901

Various optimizations and cosmetics
Update AUTHORS file with Gabriel and me
update XCHG macro to work correctly in if statements
Add new lookup tables for block_idx and fdec/fenc addresses
Slightly faster array_non_zero_count_mmx (patch by holger)
Eliminate branch in analyse_intra
Unroll loops in and clean up chroma encode
Convert some for loops to do/while loops for speed improvement
Do explicit write-combining on --me tesa mvsad_t struct
Shrink --me esa zero[] array
Speed up bime by reducing size of visited[][][] array

r900

Resolve floating point exception with frame_init_lowres mmx
In some cases, the mmx version of frame_init_lowres could leave the FPU uninitialized for use in ratecontrol, resulting in floating point exceptions.
Since frame_init_lowres is such a time-consuming function, an emms was just put at the end, since it costs almost nothing compared to the total time of frame_init_lowres.

x264 Revision Memo (8xx)

2008-07-04T18:32:00.003+09:00

x264 Revision Memo (9xx)

r899

Update my email address

r898

Update file headers throughout x264
Update "Authors" lists based on actual authorship; highest is most important
Update copyright notices and remove old CVS tags from file headers
Add file headers to GTK and other sections missing them
Update FSF address
Other header-related cosmetics

r897

denoise_dct asm

r896

cosmetics in permutation macros
SWAP can now take mmregs directly, rather than just their numbers

r895

Fix bug in adaptive quantization
In some cases adaptive quantization did not correctly calculate the variance.
Bug reported by MasterNobody

r894

lowres_init asm
rounding is changed for asm convenience. this makes the c version slower, but there's no way around that if all the implementations are to have the same results.

r893

Optimizations and cosmetics in macroblock.c
If an i4x4 dct block has no coefficients, don't bother with dequant/zigzag/idct. Not useful for larger sizes because the odds of an empty block are much lower.
Cosmetics in i16x16 to be more consistent with other similar functions.
Add an SSD threshold for chroma in probe_skip to improve speed and minimize time spent on chroma skip analysis.
Rename lambda arrays to lambda_tab for consistency.

r892

some asm functions require aligned stack. disable these when compiling with msvc/icc.

r891

Move bitstream end check to macroblock level
Additionally, instead of silently truncating the frame upon reaching the end of the buffer, reallocate a larger buffer instead.

r890

Convert NNZ to raster order and other optimizations
Converting NNZ to raster order simplifies a lot of the load/store code and allows more use of write-combining.
More use of write-combining throughout load/save code in common/macroblock.c
GCC has aliasing issues in the case of stores to 8-bit heap-allocated arrays; dereferencing the pointer once avoids this problem and significantly increases performance.
More manual loop unrolling and such.
Move all packXtoY functions to macroblock.h so any function can use them.
Add pack8to32.
Minor optimizations to encoder/macroblock.c

r889

mc_chroma_sse2/ssse3

r888

checkasm --bench=function_name

r887

interleave psnr/ssim computation with reference frame filtering, to improve cache coherency

r886

Add more inline asm and a runtime check for MMXEXT support
x264 will now terminate gracefully rather than SIGILL when run on a machine with no MMXEXT support.
A configure option is now available to build x264 without assembly support for support on such old CPUs as the Pentium 2, K6, etc.

r885

Use aligned memcpy for x264_me_t struct and cosmetics

r884

Cosmetics and loop unrolling
GCC is not very good at loop unrolling in cases where it can perform constant propagation, so the unrolling unfortunately has to be done manually.

r883

Fix regression in 64-bit in r882
i_mvc needs to be 64-bit when used with a 64-bit memory pointer

r882

More tweaks to me.c
Added inline MMX version of UMH's predictor difference test
Various cosmetics throughout me.c
Removed a C99-ism introduced in r878.

r881

Fix regression in r736
r736 added intra RD refinement to B-frames; however, it is possible for subme=7 to be used without b-rdo.
This means intra RD isn't run, and therefore it is possible for intra chroma analysis to not have been run, since update_cache was never called for an intra block, and chroma ME is not required even at subme=7.
r801, which removed a memset, made this worse because previously the chroma prediction mode was at least initialized to zero; now it was not initialized at all.
Therefore, --no-chroma-me, --subme 7, and no --b-rdo had the potential to crash.
This change restricts intra RD refinement to only be run when --b-rdo is enabled (sensible to begin with), thus preventing a crash in this case.

r880

Fix regression in r850
Bug resulted in rare incorrect chroma encoding

r879

Cosmetics in VBV handling

r878

Tweaks and cosmetics in me.c
Use write-combining for predictor checking and other tweaks.

r877

Partially inline trellis quantization
Inlining trellis into the 4x4/8x8 trellis wrappers increases trellis speed by about 5-10% through constant propagation.

r876

Various cosmetic changes.

r875

avg_weight_sse2

r874

many changes to which asm functions are enabled on which cpus.
with Phenom, 3dnow is no longer equivalent to "sse2 is slow", so make a new flag for that.
some sse2 functions are useful only on Core2 and Phenom, so make a "sse2 is fast" flag for that.
some ssse3 instructions didn't become useful until Penryn, so yet another flag.
disable sse2 completely on Pentium M and Core1, because it's uniformly slower than mmx.
enable some sse2 functions on Athlon64 that always were faster and we just didn't notice.
remove mc_luma_sse3, because the only cpu that has lddqu (namely Pentium 4D) doesn't have "sse2 is fast".
don't print mmx1, sse1, nor 3dnow in the detected cpuflags, since we don't really have any such functions. likewise don't print sse3 unless it's used (Pentium 4D).

r873

enable ssse3 phadd satd on Penryn.

r872

benchmark most of the asm functions (checkasm --bench).

r871

Cosmetic: fix C99-ism

r870

Use a gaussian window for cplxblur
Cplxblur was originally intended to use a gaussian window,
but in its current form did not.
This change provides a tiny improvement to 2pass ratecontrol.

r869

cosmetics

r868

nasm compatible NX stack

r867

CQP is incompatible with AQ

r866

memzero_aligned_mmx

r865

binmode stdin on mingw, not just msvc

r864

omit redundant mc after non-rdo dct size decision, and in b-direct rdo

r863

allow fractional CRF values with AQ.

r862

fix some uninitialized partitions in rdo

r861

2-pass VBV support and improved VBV handling
Dramatically improves 1-pass VBV ratecontrol (especially CBR) and provides support for VBV in 2-pass mode.
This consists of a series of functions that attempts to find overflows and underflows in the VBV from the first-pass statsfile and fix them before encoding.
1-pass VBV code partially by Dark Shikari.

r860

Fix noise reduction in threaded mode.
Previously enabling noise reduction with threads had no effect.
Note that this is not an optimal solution; each thread still tracks noise reducation separately (unlike in single-threaded mode).

r859

fix a crash on win32 with threads.
r852 introduced an assumption in deblock that the stack is aligned.

r858

remove nasm version check. a feature check is all that's needed.
silence stderr in yasm version check.

r857

cosmetics in cabac

r856

faster residual_write_cabac

r855

change DEBUG_DUMP_FRAME to run-time --dump-yuv

r854

x264_median_mv_mmxext
this is the first non-runtime-detected use of mmxext, but it has to be inlined

r853

factor duplicated code out of deblock chroma mmx

r852

deblock_luma_intra_mmx

crash on many systems, use recommended revision

r851

write aspect ratio in mp4

r850

omit delta_quant in i16x16 blocks with no residual
(all other block types were already covered, but i16x16 cbp is special)

r849

explicit write combining, because gcc fails at optimizing consecutive memory accesses

r848

force unroll macroblock_load_pic_pointers
and a few other minor optimizations

r847

quant_2x2_dc_ssse3

r846

r836 borked lossless cabac nnz

r845

use elf instead of a.out on netbsd

r844

fix x264_realloc when not using libc realloc.

r843

don't pretend to support win64. remove all related code.
it hasn't worked since probably some time in 2005, and won't ever be fixed unless someone steps up to maintain it.

r842

cosmetics: replace last instances of parm# asm macros with r#

r841

remove DEBUG_BENCHMARK

r840

faster probe_skip

r839

drop support for pre-SSE3 assemblers

r838

s/x264_cpu_restore/x264_emms/
no point in giving it a generic name when it's not generic

r837

faster cabac_mb_cbp_luma
ported from ffmpeg

r836

remove some redundant nnz counts
move some nnz counts from macroblock_encode to cavlc if cabac doesn't need them

r835

compute missing nnz count in subme7 cavlc

r834

remove a division in macroblock-level bookkeeping

r833

omit P/B-skip mc from macroblock_encode if the pixels haven't been overwritten since probe_skip

r832

earlier termination in SEA if mvcost exceeds residual

r829

Fix define of illegal identifier (as defined in section "7.1.3 Reserved identiers" of C99 spec) "__UNUSED__", and use the one defined in common/osdep.h, i.e. "UNUSED"
based on a patch by Diego Biurrun

r828

more consistent include name (in line with other PPC includes)

r827

fix illegal identifiers in multiple inclusion guards
patch by Diego Biurrun % diego A biurrun P de %

r826

AQ now treats perfectly flat blocks as low energy, rather than retaining previous block's QP.
fixes occasional blocking in fades.

r825

checkasm cabac

r824

s/movdqa/movaps/g

r823

--asm to allow testing of different versions of asm without recompile

r822

copy left neighbor pixels directly from previous mb instead of main plane

more hpel fixes

r818

update msvc projectfile

r817

r810 borked hpel_filter_sse2 on unaligned buffers

XP SP3正式版きたー＼(^o^)／
IT プロフェッショナルおよび開発者用 Windows XP Service Pack 3 ネットワークインストールパッケージ

早速適用させたらStyleXPが未対応のようでVisualStyleが適用出来ない
色々調べたらSystem32のuxtheme.dllが関係しているようだった。

ResourceHackerでuxtheme.dllを開いてVersion Infoの以下の2つを修正

FILEVERSION
6,0,2900,5512 -> 6,0,2900,2845
PRODUCTVERSION
6,0,2900,5512 -> 6,0,2900,2845

修正したらReplacerを使用して既存の物と置換して再起動する
これでStyleXPでVisualStyleを適用出来ました。

※StyleXPが対応するまでの暫定処置なので自己責任でお願いします。

GradFunkMirrorというgradfun2dbの改造版みたいな関数があったので早速使ってみる

# Border processing fix for GrandFun by MugFunky and Alain2
# Edit by Soulhunter: Changed strength from int -> float

Function GradFunkMirror( clip c, float "strength" )
{
strength = default( strength, 1.2 )
w = c.width()
h = c.height()
vflip = c.FlipVertical()
hflip = c.FlipHorizontal()

MS製マウス用ドライバのIntelliPointとキーボード用ドライバのIntelliType Proですが
バージョン6.2から自動アップデートチェックのプログラムが常駐するようになり
ドライバのプログラムと同時に起動するような感じみたいなので
アップデートチェックのプログラムのみの自動起動を阻止する事が出来ないようです。
ということで対応しているドライバがv6.2しかないという以外はお勧めしない

色空間について自分なりにメモ

2008-03-29T12:52:00.001+09:00

DTVでの色空間(Color Space)は現在RGB(PC向け)とYUV(TV向け)の2種類が普及している。
最近xvYCCという規格が出来たようですが、普及にはもう少し時間がかかりそう

RGBはRed(赤)・Green(緑)・Blue(青)の3色で構成されている。
YUVはY{明るさ(Luma)}・U(明るさと青の差)・V(明るさと赤の差)で構成されている。
YCbCr(画像や動画等)やYPbPr(アナログTV等)という呼び方もあって紛らわしい
UとVは同じ色差(Chroma)ということでまとめてYCとかで表記されることも

各規格の表記の違いについて
RGBは使用している色数のビット数を語尾に表記

RGB8: 256色
RGB16: 65,536色 (High Color)
RGB24: 16,777,216色 (True Color)
RGB32: 16,777,216色+透過度 (True Color + Alpha)

YUVはRGBと比べると非常に複雑で分かりにくく面倒くさい
サンプル比表記(YUV+数字)の場合は以下の3種類

数字3桁: Yを幅4ピクセル基準としてのUとVのそれぞれのピクセル比率
例: YUV444、YUV422(YUV211)、YUV411
数字2桁以下: 1ピクセルあたりのビット数
例: YUV24、YUV16、YUV12、YUV9
数字3桁(1桁が0): 説明するのが難しい
例: YUV420、YUV410

FourCCと呼ばれる4文字の圧縮形式での表記する場合は以下の2種類

Packed Format (色差を水平方向に間引いて同一配列で格納)
例: UYVY(UYNV)、YUY2(YUNV/V422)、YVYU、YVYU、IYU1、IYU2
Planer Format (色差をブロック単位で間引いて異なる配列で格納)
例: YV24、YV16、YV12、IYUV(I420)、YVU9

これ以外にY+ビット数の白黒映像(Gray Scale)の表記がある

同じ意味を持つ表記をまとめると以下の4種類に分類される

YUV444、YUV24、IYU2、YV24
YUV422、YUV211、UYVY(UYNV)、YUY2(YUNV/V422)、YVYU、YV16
YUV411、YUV12、YUV420、IYU1、 IYUV(I420)、YV12
YUV9、YUV410、YVU9

RGBとYUVの変換(Color Matrix)について
色空間の変換式には規格が存在しており、規格を策定した団体で有名なのは以下の2種類

ITU-R (国際電気通信連合無線通信部門)
旧称CCIR (国際無線通信諮問委員会)
SMPTE (米国映画テレビ技術者協会)

それぞれの規格団体名の後に規格名という形式で記述されている

変換式はSD画質用とHD画質用の2種類が主に使用されており
走査線の本数でどちらか判断している(走査線の本数にはばらつきがある)

SD: 約480本、それ以下
例: ITU-R BT.601、ITU-R BT.470、SMPTE 170M

HD: 約720本、約1080本
例: ITU-R BT.709、SMPTE 240M

SMTPE 240M

この他にFCCというのもあるみたいだけど日本じゃ殆ど見掛けない気がする
それからYUVとYCbCrは変換式に微妙に違いがあるらしい

まとめる時にここやここ等を参考にした

VSFilter

2008-03-26T08:14:00.005+09:00

VSFilterをAviSynthのプラグインフォルダの物と差し替えたら
アクセス違反とかでてavsファイルを全く開けない状態になった。
原因はよく分からないけど要注意

FilterRange

2008-03-25T06:52:00.005+09:00

AviSynthでFilterRange関数を使うと指定範囲のみにフィルタを適用出来るというのがあります。
FilterRangeを使ってクリップの最終フレームを含んだ範囲に適用させると
最終フレームの後に1フレーム追加されるバグがあるようです。

にーやん氏の改造した関数をメモ

function FilterRange(clip clip, int "start", int "end", string "filter")
{
final_frame = clip.FrameCount()-1
Assert(end <= final_frame, "end が最終フレームよりも大きい")
c1 = start < 2 ? clip.trim(0, -1) : clip.trim(0, start - 1)
c2 = Eval("clip.trim(start, end)." + filter)
c3 = clip.trim(end + 1, 0)
c = start == 0 ? c2 : c1 + c2
c = ((end == 0) || (end == final_frame)) ? c : c + c3
return c
}

3/26追記
にーやん氏が更に改造を加えたようなのでそっちもメモ

# FilterRange 改造版
function FilterRange(clip clip, int "start", int "end", string "filter") {
# 最終フレーム番号の取得
final_frame = clip.FrameCount() - 1
# デフォルト値の設定
start = default(start, 0) # 指定なしなら先頭フレーム
end = default(end, final_frame) # 指定なしなら最終フレーム
filter = default(filter, "") # あとで例外処理に使う
# 例外処理
Assert(end <= final_frame, "'end' should be less than or equal to " + String(final_frame) + ".")
Assert(filter != "", "'filter' should be specified.")
# start から end までを選択してフィルタを適用し c に代入
c = Eval("clip.trim(start, end)." + filter)
# start が 0 ならそのまま c のみ、1 ならフレーム 0 と c を結合、それ以外は start より前の範囲と c を結合
c = (start == 0) ? c
\ : (start == 1) ? clip.trim(0, -1) + c
\ : clip.trim(0, start - 1) + c
# end が 0 か最終フレームなら c のみ、さもなければ c と end より後ろの範囲を結合
c = ((end == 0) || (end == final_frame)) ? c
\ : c + clip.trim(end + 1, 0)
# c を返す
return c
}

とうとうAviSynthのみに…

2008-02-27T08:56:00.005+09:00

自動フィールドシフトとインタレ解除２のパラメータを色々いじってはみたんですが、
縞解除を重視すると所々でちらつきが発生してしまう。
かといってちらつかないように設定すると縞解除漏れが発生する部分があったりで
場面毎に色々設定してるんじゃ自動フィールドシフトの意味ねぇじゃん('A`)となりました。

Wavelet3DNR2とかWaveletType-Gも綺麗にノイズ除去してくれて重宝していましたが
アニメ素材の場合はｘ264でエンコードすると綺麗になりすぎてバンディングが発生してしまう
バンディング除去を途中に挟んでも最終的にはバンディングが･･･

以上の2つの要因が重なってAviUtlを使う必要が薄れたのでAviSynth一本で頑張ってみようと決心

まるも氏のMPEG2プラグインで映像を読み込み
Trimで範囲指定
Itsで逆テレシネとインタレ解除を切り替えてtimecode出力
- 24fps部分
  BruteIVTC().vinverse().TDecimate(mode=1)
- 60fps部分
  TDeint(mode=2) #Blend
  TDeint(mode=1) #Bob
ColorYUY2で色調補正
Cropで無効領域カット
EEDI2でアプコンしてLanczosResize(taps=16)でスケーリング
Convolution3Dでノイズ除去
WarpSharpとMSharpenで先鋭化
ColorMatrixでSMPTE240Mに変換
banding6でバンディング除去
YV12変換
gradfun2dbでYV12変換時のバンディング除去

x264で↑のavsをrawエンコード
tc2mp4Modでtimecodeを取り込みrawをmp4(vfr)に変換
MP4Boxで映像と音声をMuxして完了

以上のバッチファイルを作成してエンコしてみたら意外と速度が出て驚き
以前は中間出力(5時間)→アプコン+その他をx264でエンコ(20時間超)だったんですが
中間出力分の時間をショートカットできそうな結果になりました。

CoreAVC+DeBand

2008-02-24T07:22:00.012+09:00

CoreAVCでffdshowのバンディング除去を使うメモ

再生するプレイヤーの出力設定をOverlay Mixerにする
CoreAVCの出力設定でYV12を最優先にする
ffdshowのコーデックにあるRaw videoのデコーダをYV12に設定
オーバーレイとDeBandにチェックを入れる
サポートされた出力色空間のYV12にチェックを入れる

AviUtl Mod Patch

2008-02-14T19:11:00.003+09:00

AviUtl v0.99bの見た目をちょっと変更するパッチを作成

[変更点]

表示フォントをMS UI Gothicに変更
一部文字を修正
「フィルタの順序」の高さを調整
XPのVisualStyleを適用

自動フィールドシフトのメモ

2008-02-12T14:14:00.000+09:00

アニメ素材

プリセット映画/アニメ
切替点 0
判定比 256
縞(解除) 0
C動き 0

これでフェードイン、フェードアウトのシーンの縞も結構解除してくれる気がする
解除Lv3だと静止している場面のテロップ等が少し汚くなる傾向有り
酷い場合はプロファイルを別に作成して解除Lvを変更してやると良い感じ
インタレ縞の解除漏れはインターレース解除2で調整して処理

tete版Firefox+TMOZDLL

2008-02-10T16:15:00.000+09:00

綾川版Firefoxにしたばかりなんですがtete版に乗り換えることに
私的ビルド専用DLLと共に使用したら綾川版より早くなった気がする

綾川版Firefox

2008-02-08T05:08:00.000+09:00

Firefox 2.0.0.12が出たので以前から気になっていた綾川版Firefoxに乗り換えることに

そのままではUIが英語なので日本語に変更をしないといけないようだ
普通に上書きして起動した後にabout:configを開いて
general.useragent.localeの値をen-USからjaに変更して再起動
これで普通のFirefoxから上書きインストールならUIが日本語になるはず
表示されない場合は言語パックの導入が必要らしい

それからそのままではタイトル表記とかがBon EchoなのでこれをFirefoxにする
about:configを開いてgeneral.useragent.extra.firefoxの値を
Bon Echo/バージョンからFirefox/バージョンに変更して再起動
これでたぶん公式のFirefoxと同じ感じになると思います。

セーフモードで起動する時は英語になってしまうようなので
-UILocale jaというコマンドラインの追加が必要

コンパイラの問題

2008-02-01T01:58:00.000+09:00

最近はIntelのC2Dが最もメジャーなCPUとなってしまっているようで
それに伴いソフトのコンパイラもICC(Intel C++ Compiler)でコンパイルされてるのが多い

自分のメインPCは少し前のAMD Athlon64なのでICCでコンパイルされたソフトは
IntelのCPU以外だと遅くなるという記事をちらほら見かけて悩む

そこでソース公開されているソフトをVC9(MS Visual C++ 2008)で
コンパイル出来ないかと色々と試行錯誤をしています
しかしプログラミングなんか囓った物を更に囓った程度しか分からない自分にはさっぱり

x264 p4x4でググったらこんなメモが一番先頭に来るようになってしまった／(^o^)＼

fb2kのPanelsUI使用時の強制終了を減らす

2008-01-03T19:01:00.000+09:00

foobarでPanels UIを日本語環境で使用するとウンザリするほど強制終了を喰らいます

Microsoft純正のAppLocaleというシステムロケールを一時的に変更するのがあるんですが
最初使っていた時はエラー出なくなって＼(＾o＾)／だったんですが・・・
問題は起動する度に毎回確認ダイアログが出現してウザったくなってしまいました

そこで他に方法はないかと調べたら、台湾の人が改造したpAppLocaleというソフトを発見
こっちは毎回ダイアログが出ずに快適なのでお勧めです

mp4をポップアップ表示で再生させる実験

Requirements

Adobe Flash Player ver 9.0.115

JavaScript

Firefox 2.x (Recommended) or Opera 9.x

今回はHighslideとJW FLV Media Playerを使ってmp4(h.264+AAC)をポップアップ表示で再生させてみました。
問題はエンコした動画を置く場所がなかなか見つからなくて上限が10MBと厳しいけどMediaMaxにUP
