Kostya Shishkov	74a30595b2	Edge emulation should be used in B-frame MC in mspel mode with mv_x < 1 or mv_y < 1. Originally committed as revision 19255 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	351653a51e	VC-1/WMV: Remove redundant ff_init_block_index() calls. These are only supposed to be called once per row, not once per macroblock. ~1.5% faster according to oprofile. Originally committed as revision 19213 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	010f98f96a	VC-1/WMV3 decoding: don't clear blocks unless they're actually used. ~8% faster VC-1 decoding. Possible future optimization: clear blocks after use instead of before, and for DC-only blocks, only clear the DC coefficient. Originally committed as revision 19205 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Jason Garrett-Glaser	4f717c69ed	idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall. Includes mmx2 asm for the various functions. Note that the actual idct still does not have an x86 SIMD implemtation. For wmv3 files using regular idct, the decoder just falls back to simple_idct, since simple_idct_dc doesn't exist (yet). Originally committed as revision 19204 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	b761659bef	Split decoder-specific code off from vc1.c into vc1dec.c and keep code shared between decoder and parser in vc1.c. Originally committed as revision 19152 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Baptiste Coudurier	35b2c65756	vc1 and wmv3 decoders use MPV_frame_start which uses get_buffer, set CODEC_CAP_DR1 Originally committed as revision 19111 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Baptiste Coudurier	87e302bfd8	remove unused hack which set AVCodecContext frame_number to pic timestamp Originally committed as revision 18988 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Baptiste Coudurier	2d05bc8641	set pict_type in VC-1 parser, fix some timestamps problems Originally committed as revision 18987 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Benjamin Larsson	10c773c12f	Remove dead assignments found by CSA Originally committed as revision 18730 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kostya Shishkov	b750fb6945	Display dimensions should not affect the real size of coded frame, thus set only avctx->{width,height} and don't touch coded_{width,height} when parsing them. This fixes the case when coded and display dimensions differ by more than one macroblock. Originally committed as revision 18665 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kostya Shishkov	21fce71fd1	Switch VLC tables in WMV3/VC-1 decoder to new static init method Originally committed as revision 18658 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

David Conrad	6cecd63005	VC1: Do qpel when needed for both MVs in a B frame Originally committed as revision 18511 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Carl Eugen Hoyos	e161e007be	Use INIT_VLC_USE_STATIC and not its value "1". Originally committed as revision 18430 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist.
