Merge remote-tracking branch 'qatar/master'
* 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.
