Michael Niedermayer	2b3b52d519	lagarith: fix alignment on buffers passed into prediction dsp code. This should fix issues with direct rendering Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Hendrik Leppkes	f9150c8ac0	lagarith: frame multithreading About 2x speedup going from 1 to 2 threads. 1.7s to 0.85s on foreman CIF. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	13 years ago
Ronald S. Bultje	7191e1c490	lagarith: fix color plane inversion for YUY2 output.	13 years ago
Ronald S. Bultje	98d0d19208	lagarith: pad RGB buffer by 1 byte. For left HFYU prediction, we predict from the buffer buf+1 using 8- or 16-byte reads. This means that aligning the buffer by 16 bytes is in itself not sufficient, because if the width itself is 16- or 8-byte aligned, the buffer will not be padded, and thus a read of size 16 at buf+1 will overflow boundaries at the right edge. Padding the buffer by 1 byte is sufficient to not overflow its boundaries. Fixes bug 342.	13 years ago

Carl Eugen Hoyos	eae77f4631	Fix lagarith YUY2 output.	14 years ago
Kostya Shishkov	464e9ab011	lagarith: add YUY2 decoding support Unlike other variants, for YUY2 we need to use different prediction: * on line 0 for luma we should left predict starting from the second pixel * on line 1 we should left predict first 4 pixels for luma and 2 for chroma * median prediction employed here is taken directly from HuffYUV	14 years ago
