 The MXF demuxer does not set AVStream::avg_frame_rate and
 AVStream::::r_frame_rate. As a result, the MOV muxer, which uses
 AVStream::avg_frame_rate to determine the timecode frame rate, will fail
 when copying a track:

 {{{ffmpeg -f imf -i countdown-small/CPL_bb2ce11c-
 1bb6-4781-8e69-967183d02b9b.xml -map 0 -c copy -t 5 -shortest
 build/out.mov}}}

 Suggest setting the avg_frame_rate and r_frame_rate of the video stream to
 the edit_rate of the MXF track.
