Michael Niedermayer	493296800c	avcodec/mjpegdec: parse avid data from extradata Makes no difference for any file tested but is needed for following bug-fix Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	98f9aa389b	avcodec/mjpegdec: switch interlaced_polarity to 0 for PAL AVID 0 should have been the default, this change should make no difference but this is needed for the following bugfix Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	6904168c79	avcodec/mjpegdec: Print error in case of CMYK Also fail if AV_EF_EXPLODE is set. We do not fail by default, but rather return some image as it may be usefull to the end user to see what is on the image, for example text could be read quite fine and objects recognized.

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).
