Alexander Strange	0b69d6254f	H.264: Use 64-/128-bit write-combining macros for copies 2-3% faster decode on x86-32 core2. Originally committed as revision 21440 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Justin Ruggles	008f872f61	Only check frame size if the header is valid. Originally committed as revision 21439 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(). Another such context variable was added in r18381. Originally committed as revision 21438 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	996b099a0f	Branchless setting of MB_TYPE_8x8DCT. Not benchmarked as i failed to find a sample that uses this one. But it should be faster. Originally committed as revision 21435 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	81afcf1fae	Remove cruft. Originally committed as revision 21434 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	d9ef0d2e14	Mark index as unsigend so gcc knows it doesnt need a sign extension on x86_64. Any tips on how i can convince gcc that it doesnt need a mov %eax, %eax in every get_bits() ? Originally committed as revision 21433 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	449d1442a6	a[b-1] -> (a-1)[b]. Helps gcc not to add seperate -1 instructions. Originally committed as revision 21432 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Reimar Döffinger	0b882b4009	Fix crash in MLP decoder due to integer overflow. Probably only DoS, init_get_bits sets buffer to NULL, thus causing a NULL-dereference directly after. Originally committed as revision 21426 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	8ba436171f	1 cpu cycle faster suffix_length calculation. Originally committed as revision 21425 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Laurent Aimar	f0f86627fe	VC-1/WMV3 DXVA2 implementation It allows VLD VC-1/WMV3 decoding using DXVA2 (GPU assisted decoding API under VISTA and Windows 7). It is implemented by using AVHWAccel API. Originally committed as revision 21424 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	ea3b456dd6	make mv_cache init 64bit where possible. Originally committed as revision 21412 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Laurent Aimar	85167c46ef	Moved reusable functions from dxva2_h264.c to dxva2.c Originally committed as revision 21407 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	0c32e19d58	Move +52 from the loop filter to the alpha/beta offsets in the context. This should fix a segfault, also it might be faster on systems where the +52 wasnt free. Originally committed as revision 21406 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	6231d0983b	Release buffer when the codec is closed. Originally committed as revision 21405 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	b9e3f85dbc	Use qstride = 0 and allocate only a single line for qscale_table since for this codecs all quants are the same for a single frame. Originally committed as revision 21404 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Laurent Aimar	e4833b5d71	Added ff_dxva2_ prefix to get_surface(_index) and commit_buffer functions. Originally committed as revision 21403 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	1cc2d21175	Set edges based on cbp and mv partitioning, not just skiped MBs. This is faster for videos that have lots of MBs that fall in this category. Originally committed as revision 21400 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	87ac0c0a39	Use AVPALETTE_COUNT instead of hard-coding 256. This is consistent with other codecs and will also avoid a crash on the memcpy to data[1] if AVPALETTE_SIZE ever increases. Originally committed as revision 21399 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	ab8075a2da	Remove redundant initialization of the palette, it is part of the context and that one is always 0-initialized already. Originally committed as revision 21398 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	933bea77e5	Optmize 8x8dct check used to skip some borders in the loop filter. 4 cpu cycles faster. Originally committed as revision 21396 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	6242b1c424	Use av_freep intead of av_free to free pointers in vp56 context. Originally committed as revision 21395 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	48c65d0dc9	Zero the frame data on allocation for VB codec, e.g. the FATE sample seems to rely on this. Originally committed as revision 21394 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Daniel Verkamp	a7e6328cba	Export wma_critical_freqs as ff_wma_critical_freqs Originally committed as revision 21391 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	e62a55b92e	The SSSE3 version of dct_quantize in mpegvideo_mmx_template.c needs inv_zigzag_direct16 16-byte aligned, so mark it appropriately. Fixes encoder crashes e.g. with MPlayer's -vf lavc. Originally committed as revision 21389 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	3deb53849e	Implement an sse version of scalarproduct_float(). Originally committed as revision 21386 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Kostya Shishkov	2727649677	Zero palette in case not all entries are initialized later Originally committed as revision 21384 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c67278098d	Move array specifiers outside DECLARE_ALIGNED() invocations Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	258b60c224	Gcc idiocy fixes related to filter_mb_edge*. Change order of operands as gcc uses a hardcoded register per operand it seems even for static functions thus reducing unneeded moved (now functions try to pass the same argument in the same spot). Change signed int to unsigned int for array indexes as signed requires signed extension while unsigned is free. move the +52 up and merge it where it will end as a lea instruction, gcc always splits the 52 out there turning the free +52 into an expensive one otherwise. The changed code becomes a little faster. Originally committed as revision 21375 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	1f445f5473	Move dquant check into qscale overflow check. This should be faster (couldnt meassue a difference), and its less picky on slightly out of spec dquant. Originally committed as revision 21373 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	31f6e3c19e	Make calculation of mask_edge free of branches, faster of course but probably little effect overall as this is not that often executed. Originally committed as revision 21366 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	e9e949cf74	Clarify CODEC_CAP_SUBFRAMES. Originally committed as revision 21364 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	2a58e45724	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. Originally committed as revision 21362 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	1f630b9717	Use two separate memory arguments since 8+() is invalid gas syntax Originally committed as revision 21360 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
