[FFmpeg-devel] [PATCH v2 6/7] avformat/mxfenc: allow all frame rates if -strict mode is set to unofficial or lower

[Marton Balint]

There was no consensus wheter or not to allow unofficial frame rates due to
possible interoperability issues, a compromise is to only allow it if -strict
mode is set to unofficial.
