ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Mon Apr  5 10:47:10 2021 +0200| [04feb1c0382104c36d2297a277ffd1450d016d35] | committer: Anton Khirnov

lavf: do not derive timebase from avg_frame_rate

avg_frame_rate is the _average_ framerate, its presence does not
guarantee that the stream is CFR, so it should not be used for setting
the timebase.
