* qatar/master: mpegvideo_enc: use the AVFrame API properly. ffv1: use the AVFrame API properly. jpegls: use the AVFrame API properly. huffyuv: use the AVFrame API properly. Conflicts: libavcodec/ffv1.c libavcodec/ffv1.h libavcodec/ffv1dec.c libavcodec/ffv1enc.c Changes to ffv1 are more redone than merged due to them being based on an ancient codebase and a good part of that having being done already as well.

2013-08-26ffv1enc: Make ffv1.3 non experimentalMichael Niedermayer
The fate tests change as they used 1.2 previously The increased size is due to: 32bit CRCs per slice by default (can be disabled), it adds slice headers to allow decoding one slice without the others an additional slice size field is added to make it possible to find slices within corrupted surroundings. these add up to about 57bit per slice more at 50 frames and 4 slices thats 1425 byte Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
