* h264: K&R formatting cosmetics for header files (part I/II)Diego Biurrun2012-05-10

* h264: Factorize declaration of mb_sizes array.Diego Biurrun2012-04-05
|
* h264: Make ff_h264_decode_end() static, it is not used externally.Diego Biurrun2012-03-30
| | | | Also drop the now unnecessary ff_ prefix from its name.
* h264: disallow constrained intra prediction modes for luma.Ronald S. Bultje2012-02-09
| | | | | | | | | | | Conversion of the luma intra prediction mode to one of the constrained ("alzheimer") ones can happen by crafting special bitstreams, causing a crash because we'll call a NULL function pointer for 16x16 block intra prediction, since constrained intra prediction functions are only implemented for chroma (8x8 blocks).

* Revert "h264: skip start code search if the size of the nal unit is known"Janne Grunau2011-12-19
| | | | This reverts commit 87eebb3454ff0cd6af6ebf9e1d31bdfd1c3b601b.
* h264: skip start code search if the size of the nal unit is knownJanne Grunau2011-12-18
| | | | | | | | Start code emulation prevention is only required in Annex B bytestream packed NAL units. For other coding formats the size is already known. Looking for a start code prefix can result in false positives like in http://streams.videolan.org/streams/mp4/Mr_MrsSmith-h264_aac.mp4 which has a false positive in the SPS.
* error_resilience: use the ER_ namespaceLuca Barbato2011-12-13

* h264: fix frame reordering code.Ronald S. Bultje2011-12-03
| | | | | Fixes fate-h264-conformance-{mr2_tandberg_e,mr3_tandberg_b} without requiring -strict 1.
* h264: improve calculation of codec delay.Ronald S. Bultje2011-11-05
| | | | | | Fixes the following conformance suite samples: HCBP1_HHI_A.264, HCBP2_HHI_A.264, HCMP1_HHI_A.264 (main) HCHP1_HHI_B.264, HCHP2_HHI_A.264, HCHP3_HHI_A.264 (frext)

* h264: move fill_decode_neighbors()/fill_decode_caches() to h264_mvpred.hDiego Biurrun2011-07-14
| | | | This fixes a bunch of unused function warnings.
* h264: move decode_mb_skip() from h264.h to h.264_mvpred.hDiego Biurrun2011-07-12
| | | | This resolves a circular dependency between the headers.
* h264: move h264_mvpred.h include.Ronald S. Bultje2011-07-12
| | | | | | | | 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
* Eliminate FF_COMMON_FRAME macro.Diego Biurrun2011-07-11
| | | | | 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.
* H.264: merge fill_rectangle into P-SKIP MV prediction, to match B-SKIPJason Garrett-Glaser2011-07-08
|
* 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.
* 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.

* 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

* 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
