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

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
