[FFmpeg-devel] [PATCH] ffmpeg: print proper statistics for video output when using wrapped avframe encoder

[James Almer <jamrial@gmail.com>]

pkt->size contains the size of an AVFrame struct plus some padding, which is meaningless.
Use instead the size of a raw video frame, as if it was the rawvideo encoder.
