* H.264: faster P-SKIP decodingJason Garrett-Glaser2011-07-08
| | | | | Inline the relevant parts of fill_decode_caches into P-SKIP mv prediction to avoid calling the whole thing.
* H.264: av_always_inline some more functionsJason Garrett-Glaser2011-07-08
| | | | These weren't getting inlined all the time in all gcc versions.
* H.264: template left MB handlingJason Garrett-Glaser2011-07-03
| | | | Faster H.264 decoding with ALLOW_INTERLACE off.
* H.264: faster fill_decode_cachesJason Garrett-Glaser2011-07-03
| | | | Aliasing avoidance and general cleanup.
* H.264: faster write_back_*Jason Garrett-Glaser2011-07-03
| | | | Avoid aliasing, unroll loops, and inline more functions.
* doxygen: Prefer member groups over grouping into modulesReinhard Tartler2011-07-02
| | | | | | | | | 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.
* 4:4:4 H.264 decoding supportJason Garrett-Glaser2011-06-13
| | | | Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.
* Roll back 4:4:4 H.264 for nowJason Garrett-Glaser2011-06-13
| | | | Needs some ARM/PPC asm modifications.

* Add support for higher QP values in h264.Oskar Arvidsson2011-05-10
| | | | | | | | 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>
* Add the notion of pixel size in h264 related functions.Oskar Arvidsson2011-05-10
| | | | | | | | | | 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>

* H.264/SVQ3: make chroma DC work the same way as luma DCJason Garrett-Glaser2011-01-15
| | | | | | | 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
* H.264: switch to x264-style tracking of luma/chroma DC NNZJason Garrett-Glaser2011-01-14
| | | | | | | 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
* H.264: split luma dc idct out and implement MMX/SSE2 versionsJason Garrett-Glaser2011-01-14
| | | | | | | | | | 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
* Add av_unused to decode_mb_skip declaration to fix the following warning:Eli Friedman2010-07-06

* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | 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
* Move static function fill_filter_caches() from h264.h to h264.c.Diego Biurrun2010-04-13
| | | | | | | | 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
* Fix implicit weight for b frames in mbaff.Michael Niedermayer2010-03-30

* Move H264 dsputil functions into their own structMåns Rullgård2010-03-16
| | | | | | | | | | | 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
* H264: fix signed overflow in constant multiplicationMåns Rullgård2010-03-15
| | | | | | This fixes libavcodec/h264.h:1100: warning: integer overflow in expression Originally committed as revision 22558 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove DECLARE_ALIGNED_{8,16} macrosMåns Rullgård2010-03-06
| | | | | | | 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

* Only load the topleft mv/ref when the topright is unavailable.Michael Niedermayer2010-02-26
| | | | | | 8 cpu cycles faster. Originally committed as revision 22079 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove some useless operations from the code setting left_cbp.Michael Niedermayer2010-02-26
| | | | | | maybe 0.5 cpu cycles faster Originally committed as revision 22078 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Simplify code to set cbp_*Michael Niedermayer2010-02-26
| | | | | | | | this seems 1 cpu cycle slower even though we practically just remove code. Speed loss seems caused by the merge of if(left_type), iam commiting this anyway as i cant imagine this to be anything but compiler messup.
