Paul B Mahol	4ed7c2bbc3	avcodec/utvideodec: add SIMD for restore_rgb_planes Signed-off-by: Paul B Mahol <onemda@gmail.com>	8 years ago
Paul B Mahol	3594788b71	avcodec/utvideodec: decode to GBR(A)P This is actually internal utvideo format. Allows to make use of SIMD for median prediction for rgb(a) formats, thus speeding up decoding. Simplifies code, eases further developement and maintenance. Update FATE because of pixel format switch. Signed-off-by: Paul B Mahol <onemda@gmail.com>	8 years ago

Michael Niedermayer	e473f7e659	(lib)utvideodec: remove setting of color_primaries Thanks-to: Paranoialmaniac Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Stephen Hutchinson	3f54547709	utvideo: Add ULH0 and ULH2 decoding to the native decoder. Also prevents an error since the native decoder (if enabled) is always used to probe Ut Video-encoded files, even if the user forces libutvideo to be the decoder. Without this patch, the probe would fail, and the video wouldn't get properly handed over, resulting in failure to set codec parameters. When the native decoder is disabled, libutvideo can probe and initialize decoding without issues. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
