Nicolas Gaullier ee9ae4e8ba fftools/ffmpeg: Fix honor -r output option with streamcopy 
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 updated fate test, the input is (wrongly) probed as 50fps. With
this patch, the correct value (25fps) is successfully forced with -r.

  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
