wm4	3efe0393e4	hevc: make avcodec_decode_video2() fail if get_format() fails Personally, I need the decoder to back out if get_format() returns no usable pixel format. This didn't work because the error code was not propagated down the call chain. This in turn happened because the variable declaration removed in this patch shadowed the variable, whose value is returned at the end of the function. Consequently, failures of decode_nal_unit() were ignored in this place.

Vittorio Giovara	eafbc6716c	vmnc: Delay pixel size check Some clients incorrectly set 24 as bits_per_coded_sample, while the actual value is preserved in one of the codec headers. In order to work around this, delay the check until decode_frame(). Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago

Michael Niedermayer	7786a91b47	avcodec/flacenc: Move udata and sums to FlacSubframe This significantly reduces the amount of stack space needed and also permits to simply copy the rice context again without speed penalty Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	80f9d6e0ab	avcodec/flacenc: Support calculating rice parameters exactly Some files benefit by about 0.3% from this, and speedwise its ok other files do not benefit and encode to the same size Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Steve Borho	b012bd5068	libavcodec/x265: detect csps in libx265_encode_init_csp() Without this change, if you link with an 8bit libx265 and try to specify a 10bit input color space via: ffmpeg -i in.mov -c:v libx265 -pix_fmt yuv420p10le out.mp4 It will error with: Incompatible pixel format 'yuv420p10le' for codec 'libx265', auto-selecting format 'yuv420p' With this fix, it will learn if a 10bit libx265 is available at startup, and thus allow 10bit input color spaces.

Ronald S. Bultje	900e3af857	vp9: match another find_ref_mvs() bug in libvpx. If we find a second non-sub8x8 motion vector for a non-first sub8x8 block, and the clamped value is identical to the first non-sub8x8 motion vector, then the resulting nearmv motion vector is forced to zero.	10 years ago
