Michael Niedermayer	855a1ba5e8	switch back to (amvd>2)+(amvd>32), its 5 cpu cycles faster now. Originally committed as revision 22032 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	01b35be14a	Factorize common code from the top of decode_cabac_mb_mvd() 10-15 cpu cycles faster. Originally committed as revision 22029 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	6d0155c79c	Replace mvd>2 + mvd>32 by MIN((mvd+28)*17>>9, 2) same speed as far as i can meassure but it might have fewer branches on some archs. Idea from x264 / jason Originally committed as revision 22027 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	90332debfe	Replace ad-hoc fill rectangle by fill_rectangle(). Originally committed as revision 22025 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	d2df291f73	ff_msmpeg4_decode_init() calls ff_h263_decode_init() which calls MPV_common_init(), so calling both is redundant and leads to memory leaks in WMV3/VC-1 decoder. Thus use only the first function in WMV3/VC-1 decoder initialization. Originally committed as revision 22024 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Peter Ross	601e74d366	it is not necessary to display the decoder name, as av_log() automatically prints the context Originally committed as revision 22023 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	9127a369ad	Replace /2 by faster >>1 as the mvd values are now all positive. Originally committed as revision 22013 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	5c34e36a23	Remove unused variable. Seems i forgot to commit this. Originally committed as revision 22012 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jai Menon	8790961d7e	mlp_parser: Fix memleak. ff_combine_frame() is called, which allocates ParseContext->buffer if needed, so ff_parse_close() must be called to free it. Patch by jai. Originally committed as revision 22005 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Kostya Shishkov	60819e694e	10l trocadero: Indeo 5 decoder did not free custom VLCs for macroblock and block decoding at exit, so prevent that memory leak now. Originally committed as revision 21983 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	db8cb47d15	Try to set has_b_frames in codec init if we know everything alraedy. This fixes some issues with the first few timestamps. Originally committed as revision 21976 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	9855b2e3c8	Move extradata reading code into codec init instead of doing it in read frame. Originally committed as revision 21975 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	1d6065ad08	Make Bink decoder able to skip alpha plane Originally committed as revision 21963 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	9068f36dcc	Macroblock and block Huffman code sets are to be used by both Indeo 4 and Indeo 5, so make them global and move their initialization to the common place as well. And fix static VLC initialization, as ff_ivi_create_huff_from_desc() used old way to do so. Originally committed as revision 21962 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	bb29fee3a6	Make Bink decoder to stop decoding planes after all bits are used. This prevents crashes during decoding grayscale Bink files like samples from Impossible Creatures game demo. Originally committed as revision 21961 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	39261cd8d9	get/show_bits() can read up to MIN_CACHE_BITS bits The limit for get/show_bits_long() to use get/show_bits() directly should be MIN_CACHE_BITS, not 17. Originally committed as revision 21951 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	769c497565	indent Originally committed as revision 21940 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	4c4e746566	Avoid negative shifts in build_table() A shift by a negative amount has undefined behaviour. Even though the result of this shift is never used, the shift itself could cause an exception of some kind. Originally committed as revision 21939 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Kostya Shishkov	342c7dfdbb	Bink video decoder Originally committed as revision 21937 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	d68b27a95d	VC1: fix missing include h263.h Originally committed as revision 21932 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	6cb35b45e6	Simplify determing whether fragments are coded No measurable speed difference Originally committed as revision 21931 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	a89264761f	Handle Theora's continued runs in superblock coding. This doesn't really matter yet since 4:2:0 1080p has only 3060 superblocks, but larger resolutions or 4:4:4 1080p could hit this case. Originally committed as revision 21930 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	855c720c86	Decode fully coded superblocks in the same manner as partial superblocks and qpi No speed difference, but it will simplify the special 4129 case. Originally committed as revision 21929 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	ecb51b25bb	Make the special 4129 case for long-run bit strings a #define and explain it Originally committed as revision 21928 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	33dbc1b7ca	Use memset to set the runs partially coded superblocks Much faster for long runs (e.g. nearly uncoded frames), slightly faster for the general case. Originally committed as revision 21927 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
