* 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.

|
* 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: improve qp_thresh checkJason Garrett-Glaser2011-07-08

| | | | Significantly faster deblocking in streams with lots of slices.

* H.264: fix CODEC_FLAG_GRAYJason Garrett-Glaser2011-06-13
| | | | It was broken in 4:4:4, and still did chroma deblocking for no reason in 4:2:0.
* 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 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.

* 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 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
* 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
* H264: use alias-safe macrosMåns Rullgård2010-02-18
| | | | | | | This eliminates all aliasing violation warnings in h264 code. No measurable speed difference with gcc-4.4.3 on i7. Originally committed as revision 21881 to svn://svn.ffmpeg.org/ffmpeg/trunk
