[FFmpeg-devel] [PATCH v3 3/3] fftools/ffmpeg: Fix honor -r output option with streamcopy

[Nicolas Gaullier]

Fix "ost->st->avg_frame_rate = ost->frame_rate" in streamcopy_init()
being reset to input's frame rate a few lines below.
Note that in current code, there are some discrepancies amongst the
muxers. For example, avienc relies on time_base, so it is not affected
by this patch, whereas mxfenc and matroskaenc do use avg_frame_rate,
so this patch fixes -r being honored.

In the update fate test, the input is wrongly probeb as 50fps. With
this patch, the correct value (25fps) is forced with -r.
