Anton Khirnov	9df889a5f1	h264: rename h264.[ch] to h264dec.[ch] This is more consistent with the naming of other decoders.	9 years ago

Christophe Gisquet	6a2bfd52e5	h264_ps: move and export aspect_ratio Needed for filters that may need it, like an SPS bsf. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Vittorio Giovara	d24e9a99a4	h264 does not depend on mpegvideo any more	11 years ago
Diego Biurrun	c4e43560fe	h264data: Move some tables to the only place they are used	11 years ago
Diego Biurrun	f34de1486a	h264data: Remove unused luma_dc_field_scan table	11 years ago
Michael Niedermayer	b7d1488393	h264: move q0 scan tables into context This fixes out of global array reads. The alternative solutions of checking the index or modifying the VLC tables to prevent the index going outside are each about 1-2 cpu cyclces slower per coded 4x4 block. The alternative of padding the global tables directly is more ugly and moving them to the context should benefit cache locality.

Michael Niedermayer	32e60b6bfe	h264: increase scantable sizes to avoid overread We could also check the index but this would slow speed critical code down. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 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
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	5ca43c25f6	Move setting MB_TYPE_L0L1 for direct MBs up, this is simpler. Originally committed as revision 21794 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	cc51b28299	Split cabac decoding code out of h264.c. not slower according to benchmarks. Originally committed as revision 21181 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	8e71d89a7b	Move golomb_to_int*cbp tables back to h264_data.h as svq3.c used them. Yes i did compile&test, no svq3.c was not recompiled. Originally committed as revision 21180 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	e1e949026e	Split cavlc out of h264.c. Seems to speed the code up a little... The placement of many generic functions between h264.c and h264.h is still open Currently they are a little randomly placed between them. Originally committed as revision 21178 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	889fce8e30	Split (picture\|seq) parameter set decoding out of h264.c. no speedloss meassured, also its really not touching anything that is speed relevant. Originally committed as revision 21169 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	9c09546352	Split SEI code off h264.c. Originally committed as revision 21168 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	082cf97106	Split h264 loop filter off h264.c. No meassureable speed difference on pentium dual & cathedral sample. Originally committed as revision 21159 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	903d58f631	Get rid of #include "svq3.c" functions called more than per mb are moved into the header, scan8 is also as it must be known at compiletime. The code after this patch duplicates h264data.h, this has been done to minimize the changes in this step and allow more fine grained benchmarking. Speedwise this is 1% faster on my pentium dual core with diegos cursed cathedral sample. Originally committed as revision 21157 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefan Gehrer	45beb850de	remove zigzag_scan8x8, it is the same as ff_zigzag_direct Originally committed as revision 16744 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Diego Biurrun	f107a02d4e	Move encoder-specific quantize_c and related tables to the H.264 encoder. Originally committed as revision 15937 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	ce9ff9cc52	Move #defines that are mostly used in h264.c out of h264data.h and into h264.h. Originally committed as revision 15927 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	3c54686885	Move H.264 tables that are only useful for encoding to h264enc.c. Originally committed as revision 15899 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Michael Niedermayer	44ee6135e2	Move nal unit types enum and EXTENDED_SAR #define from h264data.h to h264.h. Originally committed as revision 15534 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	0af6967ee7	chroma_format_idc=0 aka grayscale support. Can be disabled by removing #define ALLOW_NOCHROMA in case the extra if() slow the code down measurably. Fixes at least FRExt/HPCAMOLQ_BRCM_B.264 FRExt/HPCVMOLQ_BRCM_B.264 Originally committed as revision 14407 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
