* lavc: fix decode_frame() third parameter semantics for video decodersAnton Khirnov2012-12-04
| | | | It's got_frame, not data size

* lagarith: fix color plane inversion for YUY2 output.Ronald S. Bultje2012-08-03

* lagarith: pad RGB buffer by 1 byte.Ronald S. Bultje2012-08-03
| | | | | | | | | | | 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.
* lagarith: add YUY2 decoding supportKostya Shishkov2012-05-08
| | | | | | | 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
