Rafaël Carré	e9ca315dd1	Initialize thread_context[0] with h264 parser context. This allows freeing the parser memory in the thread_context freeing loop. Patch by Rafaël Carré gmailify(rafael, carre) Originally committed as revision 21508 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	592e03a8da	Change wraper functions to always inline, they are faster now that way. 1% faster MBAFF decoding overall, maybe ~0.1% faster for the cathedral sample. Originally committed as revision 21507 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	5364db2893	indent Originally committed as revision 21506 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2cf0d46d4c	Restructure check_mv() ~20 cpu cycles faster loopfilter Originally committed as revision 21505 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	fabd704b37	Restructure if() in check_mv() quite a bit faster Originally committed as revision 21504 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	ca7c784fdf	Unroll loops in check_mv() ~6% faster (slow path) loopfilter (should be ~2% overall) Originally committed as revision 21503 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	e814817b74	Factor mv/ref compare code out. This is a hair slower (0.15% maybe) but i really dont want to have the identical code duplicated 3 times because gcc adds odd threaded jumps with register reshuffling and register safe/restore. Originally committed as revision 21502 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	3b84924516	Simplify first edge filter condition. Originally committed as revision 21497 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	b6302d0c55	Cosmetics, mostly indention, 2 or so new fixme comments that i was to lazy to split out Originally committed as revision 21496 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	0a32508d90	Make the fast loop filter path work with unavailable left MBs. This prevents the issue with having to switch between slow and fast code paths in each row. 0.5% faster loopfilter for cathedral Originally committed as revision 21495 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	b304767301	get rid of the start variable. a few cycles faster Originally committed as revision 21494 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	980bcc554d	Unroll main loop so the edge==0 case is seperate. This allows many things to be simplified away. h264 decoder is overall 1% faster with a mbaff sample and 0.1% slower with the cathedral sample, probably because the slow loop filter code must be loaded into the code cache for each first MB of each row but isnt used for the following MBs. Originally committed as revision 21493 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Rafaël Carré	881b5b80da	Fix svq3_* function declarations. Patch by Rafaël Carré, rafael D carre A gmail Originally committed as revision 21489 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	e3d8807315	SVQ1: 4-byte-align codebook tables These tables are accessed as uint32 so they must be suitably aligned. Originally committed as revision 21488 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	7e2ef1b9e1	Fix possible crashes in mlp parser, it tries to go back 7 bytes after finding the 4-byte signature. Add a check that ignores the signature if we do not have enough previous data to go back at least 7 bytes. Originally committed as revision 21487 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	d780511b94	Reduce log level of "Extracting .. channel downmix" to AV_LOG_DEBUG, the message is pointless to ordinary users and is printed once per frame. Originally committed as revision 21486 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	9f72b23c5c	Revert Revision: 21362 Log: Set CODEC_CAP_SUBFRAMES for adpcm decoders This makes ffmpeg stop printing millions of Multiple frames in a packet from stream 0 when decoding adpcm. Reason: adpcm has no subframes, the flag does not belong there Originally committed as revision 21481 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Carl Eugen Hoyos	b52fcba9cd	Fix decoding ATI VCR2 codec, sample in samples/V-codecs/ATI-VCR12/ATI/VCR2test.avi Software decoding was broken since r8865, when two new context variables were added, but not initialized in vcr2_init_sequence().
