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
Stefano Sabatini	b0634fd11e	Doxument url_open(). Originally committed as revision 21437 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Carl Eugen Hoyos	895a9be60c	Force codec_tag I420 for Quicktime Planar Y'CbCr 8-bit 4:2:0 raw codec, because YV12 triggers an UV swap in rawdec.c, fixes issue 1687. Originally committed as revision 21436 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	aa2ead8215	Fix mis-computation of the needsDither variable erroneously introduced in r30419, which was causing a swscale-example regression. Also increase my liter count by 20.0 units. Originally committed as revision 30431 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	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
Michael Niedermayer	7abc860323	Optimize suffix_length computation, 1 cpu cycle speedup. Originally committed as revision 21431 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Stefano Sabatini	725b3da981	Favor the term "URL" over "filename", as the API deals with URLs rather than with simple filenames. Originally committed as revision 21429 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	c78295ad1b	Optimize level_code computation, 6cpu cycles speedup. Originally committed as revision 21428 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	f1d2b5728c	Make url_read_complete handle EAGAIN more intelligently. Only retry 2 - 5 times in quick succession and afterwards sleep a bit to avoid creating high CPU load without any progress. Originally committed as revision 21427 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

Stefano Sabatini	30b6147521	Use av_get_bits_per_pixel() for computing the bits per pixel of the source and destination format, cache those values in the newly added SwsContext:srcFormatBpp and SwsContext:dstFormatBpp fields, and remove the fmt_depth() function. Originally committed as revision 30419 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago

Ramiro Polla	a4388ebd37	Split swscale.c into scaler code (swscale.c) and utility code (utils.c). Originally committed as revision 30411 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago

kemuri	420755dd28	vfwcap: Include windows.h before vfw.h since the latter requires defines from the former. Patch by kemuri <kemuri9 at gmail dot com> Originally committed as revision 21411 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
kemuri	a1b3c5a377	Replace every usage of -lvfw32 with what is particularly necessary for that case: Avisynth -> -lavifil32 VFW Cap -> -lavicap32 Patch by kemuri <kemuri9 at gmail dot com> Originally committed as revision 21410 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ramiro Polla	27796dc3f4	Use $vfwcap_indev_extralibs variable instead of duplicating "-lvfw32" in capCreateCaptureWindow() check. Based on patch by kemuri <kemuri9 at gmail dot com> Originally committed as revision 21409 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ramiro Polla	626c46ec23	Indent. Originally committed as revision 21408 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

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
