Michael Niedermayer	7c3700cd1d	avcodec/mjpegdec: use the AVFrame width/height for flipping This makes it possible to use the code with lowres Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	af15c17daa	avcodec/mjpegdec: remove new flipping code It stored images wrong in the user provided buffers (that is you would end up with a wrongly flipped image if you used direct rendering). Also it used wrong dimensions as noticed by ubitux Enable the old code unconditionally so flipping works correctly again. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	d48132b7de	mjpegdec: apply flipping after decoding, not before This is simpler and removes a silly restriction on edges being present.	11 years ago
