[FFmpeg-devel] [PATCH] avcodec/mjpegbdec: return the amount of bytes consumed when discarding frames

[James Almer]

EAGAIN is not correct in this scenario. FFCodec.cb.decode() callback decoders
always return the amount of bytes consumed from the input packet (if any), and
report if a frame was generated by setting got_frame.
