Justin Ruggles	7d87d56ff8	Take advantage of per-channel exponent and exponent strategy layout to simplify and speed up encode_exponents(). 8% faster in function. Originally committed as revision 26357 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	5bff8590f3	Simplify compute_exp_strategy() by passing a pointer to all exponents and exponent strategies for a single channel to compute_exp_strategy_ch(). This allows for removal of the temporary pointer arrays. Originally committed as revision 26356 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	4b90c35d74	Use a local variable in the inner loop of group_exponents() to simplify the code. Originally committed as revision 26355 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	a281c6509f	cosmetics: remove unneeded braces Originally committed as revision 26354 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	5fc2e0075d	cosmetics: rename block_num to blk for variable name consistency Originally committed as revision 26353 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	0429e4a6ca	Move exp_strategy from AC3Block to AC3EncodeContext in order to arrange by channel first, then by block. Originally committed as revision 26352 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	7cc4be58b4	Rearrange exponent buffer to group all blocks for a single channel together. This will allow for faster and simpler processing of all blocks at once. Originally committed as revision 26351 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	d881a0e895	Cosmetics: fix weird indent. Originally committed as revision 26350 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	2a1f431d38	H.264/SVQ3: make chroma DC work the same way as luma DC No speed improvement, but necessary for some future stuff. Also opens up the possibility of asm chroma dc idct/dequant. Originally committed as revision 26349 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	290fabc684	Port SVQ3 to use the new mb_luma_dc method of storing luma DC coefficients. Doesn't help speed as there isn't an asm implementation yet, but consistency is a good thing. Originally committed as revision 26348 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Baptiste Coudurier	a51c71bb54	In yadif filter, default to top field first if interlacing is unknown Originally committed as revision 26347 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Sascha Sommer	3cdf69eefa	also support decoding of AVPackets with multiple wma packets fixes issue 2539 Originally committed as revision 26346 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	65344775b8	H.264: Remove useless arg to chroma_dc_dequant_idct_c Originally committed as revision 26345 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Ronald S. Bultje	ec3233a855	Fix ff_pw_3 alignment. Originally committed as revision 26344 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Baptiste Coudurier	6dc7dc08ed	In mxf muxer, check the return value of gmtime, fix #2494 Originally committed as revision 26343 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Baptiste Coudurier	90603f7c93	Update smc fate ref due to r26310 Originally committed as revision 26342 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	2e18660115	Fix SVQ3 Regression in r26336-7. Originally committed as revision 26341 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Baptiste Coudurier	0f27e6b4c2	New "copytb" ffmpeg cli option to copy input stream time base when stream copying. This should avoid non monotone timestamps for video streams with vfr. Originally committed as revision 26340 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	bd11c7a1a8	Remove outdated comment in h264dsp.h Since we no longer have non-transposed scantables, the problem it warns about no longer exists. Originally committed as revision 26339 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	0d1d01cf70	Reindent after r26337. Originally committed as revision 26338 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	5657d14094	H.264: switch to x264-style tracking of luma/chroma DC NNZ Useful so that we don't have to run the hierarchical DC iDCT if there aren't any coefficients. Opens up some future opportunities for optimization as well. Originally committed as revision 26337 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	19fb234e4a	H.264: split luma dc idct out and implement MMX/SSE2 versions About 2.5x the speed. NOTE: the way that the asm code handles large qmuls is a bit suboptimal. If x264-style dequant was used (separate shift and qmul values), it might be possible to get some extra speed. Originally committed as revision 26336 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	6c18f1cda2	Make opt_audio_sample_fmt() abort in case of invalid sample format name. Originally committed as revision 26335 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	3bf3fc0e54	Add the word "Parsed" in the parsed filter names. Originally committed as revision 26334 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	6cce172f27	Add avcore.h header in samplefmt.h. Avoid the need to manually include the avcore.h header, less error-prone. Originally committed as revision 26333 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Ronald S. Bultje	06ed024d4f	Copy metadata from ASF files contained in RTSP streams from ASF to RTSP layer, so that applications can read it also. Originally committed as revision 26332 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Ronald S. Bultje	8e8a3cc221	Reindent after 26330. Originally committed as revision 26331 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Ronald S. Bultje	7f88a5bf9b	Introduce av_metadata_copy() to copy metadata from one struct to another. Originally committed as revision 26330 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	ca32f7f208	H.264: eliminate non-transposed scantable support. It was an ugly hack to begin with and didn't give any performance. NOTE: this patch opens up some future simplifications to be made (such as removing some of the scantables from H264Context) but doesn't take advantage of them yet. Originally committed as revision 26329 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Sascha Sommer	75e4efd2a7	add support for blocksize 64 fixes issue 2537 and 2538 Originally committed as revision 26328 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago

Stefano Sabatini	8b69c2f463	Make av_get_channel_layout_string() guess the number of channels if it was not provided. Originally committed as revision 26324 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	caeb0c3027	Make avfilter_graph_free() do nothing if graph is NULL. Originally committed as revision 26323 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	b382d1e3e4	Print link audio format name in tools/graph2dot. Originally committed as revision 26322 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	0d3ee13551	Use AVERROR_INVALIDDATA rather than -1 for nutdec error codes. Originally committed as revision 26321 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago

Aurelien Jacobs	e83c716e16	don't complain about codec type/id mismatche for attachment streams Originally committed as revision 26316 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Michael Niedermayer	e3331706fc	Fix design of the pad filter. Previously the pad filter just drawed borders in the surrounding of the input without checking if this area was allocated or writeable. Now we check and allocate a new buffer if the input is unsuitable. Originally committed as revision 26315 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Michael Niedermayer	36dc00de52	Add w,h,format back into AVFilterBuffer, these are required for direct rendering. These fields are needed to be able to know which area of memory is allocated and which is off limits. This reverts 24291 and parts of r24424. Originally committed as revision 26314 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Baptiste Coudurier	4618637aca	Fix warnings: ffmpeg.c: In function ‘new_video_stream’: ffmpeg.c:3701:18: warning: ‘codec_id’ may be used uninitialized in this function ffmpeg.c: In function ‘new_audio_stream’: ffmpeg.c:3848:18: warning: ‘codec_id’ may be used uninitialized in this function ffmpeg.c: In function ‘new_subtitle_stream’: ffmpeg.c:3926:18: warning: ‘codec_id’ may be used uninitialized in this function Originally committed as revision 26313 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
