* avcodec: Remove some commented-out debug cruftDiego Biurrun2013-08-20

* h264: add a parameter to the FRAME_MBAFF macro.Anton Khirnov2013-03-21
| | | | This way it does not look like a constant.
* lavc decoders: work with refcounted frames.Anton Khirnov2013-03-08

* Remove unnecessary dsputil.h #includesDiego Biurrun2013-02-26

* h264: deMpegEncContextizeAnton Khirnov2013-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the changes are just trivial are just trivial replacements of fields from MpegEncContext with equivalent fields in H264Context. Everything in h264* other than h264.c are those trivial changes. The nontrivial parts are: 1) extracting a simplified version of the frame management code from mpegvideo.c. We don't need last/next_picture anymore, since h264 uses its own more complex system already and those were set only to appease the mpegvideo parts. 2) some tables that need to be allocated/freed in appropriate places. 3) hwaccels -- mostly trivial replacements. for dxva, the draw_horiz_band() call is moved from ff_dxva2_common_end_frame() to per-codec end_frame() callbacks, because it's now different for h264 and MpegEncContext-based decoders. 4) svq3 -- it does not use h264 complex reference system, so I just added some very simplistic frame management instead and dropped the use of ff_h264_frame_start(). Because of this I also had to move some initialization code to svq3.

* h264: increase dist_scale_factor for up to 32 referencesJanne Grunau2012-12-18
| | | | | Compute dist_scale_factor_field only for MBAFF since that is the only case in which it is used.

* w32threads: support for frame multithreadingSteven Walters2011-10-16
| | | | | | | | Replace our incomplete w32threads implementation with x264's pthreads w32threads wrapper. Relicensed to LGPL with kind permission by Pegasys Inc. Signed-off-by: Janne Grunau <janne-libav@jannau.net>

| | | | This fixes build failures with -DDEBUG in CPPFLAGS.
* 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.

* 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
* Get rid of mb2b8_xy and b8_stride, change arrays organized based on b8_stride toMichael Niedermayer2010-02-25
| | | | | | | ones based on mb_stride in h264. about 20 cpu cycles faster overall per MB Originally committed as revision 22065 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Split spatial and temporal direct MV generation.Michael Niedermayer2010-02-13
