2011-07-14h264: move fill_decode_neighbors()/fill_decode_caches() to h264_mvpred.hDiego Biurrun
This fixes a bunch of unused function warnings.
2011-07-12h264: move decode_mb_skip() from h264.h to h.264_mvpred.hDiego Biurrun
This resolves a circular dependency between the headers.
2011-07-12h264: move h264_mvpred.h include.Ronald S. Bultje
Fixes the following compile error with darwin/gcc-4.2.1: In file included from libavcodec/error_resilience.c:33: libavcodec/h264.h: In function ‘decode_mb_skip’: libavcodec/h264.h:773: error: ‘always_inline’ function could not be inlined in call to ‘pred_pskip_motion’: the function body must appear before caller libavcodec/h264.h:1334: error: called from here
2011-07-11Eliminate FF_COMMON_FRAME macro.Diego Biurrun
FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied to struct Picture. Replace by an embedded AVFrame structure in struct Picture.
2011-07-09H.264: merge fill_rectangle into P-SKIP MV prediction, to match B-SKIPJason Garrett-Glaser
2011-07-09H.264: faster P-SKIP decodingJason Garrett-Glaser
Inline the relevant parts of fill_decode_caches into P-SKIP mv prediction to avoid calling the whole thing.
2011-07-09H.264: av_always_inline some more functionsJason Garrett-Glaser
These weren't getting inlined all the time in all gcc versions.
2011-07-04H.264: template left MB handlingJason Garrett-Glaser
Faster H.264 decoding with ALLOW_INTERLACE off.
2011-07-04H.264: faster fill_decode_cachesJason Garrett-Glaser
Aliasing avoidance and general cleanup.
2011-07-04H.264: faster write_back_*Jason Garrett-Glaser
Avoid aliasing, unroll loops, and inline more functions.
2011-07-02doxygen: Prefer member groups over grouping into modulesReinhard Tartler
Before this, almost all module groups have been used for grouping functions and fields in structures semantically. This causes them to not appear properly in the file documentation and needlessly clutters up the "Modules" index. Additionally, this commit streamlines some spelling and appearances.
2011-06-144:4:4 H.264 decoding supportJason Garrett-Glaser
Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.
2011-06-14Roll back 4:4:4 H.264 for nowJason Garrett-Glaser
Needs some ARM/PPC asm modifications.
2011-06-134:4:4 H.264 decoding supportJason Garrett-Glaser
Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.

2011-05-10Add support for higher QP values in h264.Oskar Arvidsson
In high bit depth, the QP values may now be up to (51 + 6*(bit_depth-8)). Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-05-10Add the notion of pixel size in h264 related functions.Oskar Arvidsson
In high bit depth the pixels will not be stored in uint8_t like in the normal case, but in uint16_t. The pixel size is thus 1 in normal bit depth and 2 in high bit depth. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

2011-01-21Revert 2a1f431d38ea9c05abb215d70c7dc09cdb6888ab, it broke H264 lossless.Ronald S. Bultje
2011-01-15H.264/SVQ3: make chroma DC work the same way as luma DCJason Garrett-Glaser
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
2011-01-15H.264: switch to x264-style tracking of luma/chroma DC NNZJason Garrett-Glaser
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
2011-01-15H.264: split luma dc idct out and implement MMX/SSE2 versionsJason Garrett-Glaser
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
2010-07-06Add av_unused to decode_mb_skip declaration to fix the following warning:Eli Friedman

2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
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
2010-04-14Move static function fill_filter_caches() from h264.h to h264.c.Diego Biurrun
The function is only used within that file, so it makes sense to place it there. This fixes many warnings of the type: h264.h:1170: warning: ‘fill_filter_caches’ defined but not used Originally committed as revision 22876 to svn://svn.ffmpeg.org/ffmpeg/trunk

Originally committed as revision 22729 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-16Move H264 dsputil functions into their own structMåns Rullgård
This moves the H264-specific functions from DSPContext to the new H264DSPContext. The code is made conditional on CONFIG_H264DSP which is set by the codecs requiring it. The qpel and chroma MC functions are not moved as these are used by non-h264 code. Originally committed as revision 22565 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-16H264: fix signed overflow in constant multiplicationMåns Rullgård
This fixes libavcodec/h264.h:1100: warning: integer overflow in expression Originally committed as revision 22558 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-06Remove DECLARE_ALIGNED_{8,16} macrosMåns Rullgård
These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk
