Finding ffmpeg installed version

I have a cross machine script which needs to detect the version of ffmpeg as a regular version string (e.g. 2.3.8-1 or 4.1.3-0). The command

ffmpeg -version

returns a host of most likely very relevant information to others, but this is much more than what I need.

ffmpeg version 2.8.15-0ubuntu0.16.04.1 Copyright (c) 2000-2018 the FFmpeg developers

At this point I have devised commands like this:

ffmpeg -version | grep 'ffmpeg version' | sed -e 's/ffmpeg version //' -e 's/[^-0-9.].*//'

or this one which only uses a single match:

ffmpeg -version | grep 'ffmpeg version' | sed 's/ffmpeg version \([-0-9.]*\).*/\1/'

that does the trick. This works with ffmpeg version 2.x, 3.x and 4.x as far as I have tested.

Any better solutions out there?

With sed, to capture and output non space characters after ffmpeg version string:

ffmpeg -version | sed -n "s/ffmpeg version \([^ ]*\).*/\1/p;"

Edit:

To capture only the version number without dist info:

ffmpeg -version | sed -n "s/ffmpeg version \([-0-9.]*\).*/\1/p;"

Please note that you don't need:

  • to escape dot in [.]
  • to pipe your ffmpegto grep because ffmpeg -version string is in your sed pattern
