You didn't need remove anything since the guide on ffmpeg.org does not
perform a system installation, so it can co-exist with any repository
packages. If nothing depended on the "ffmpeg" package then it doesn't
really matter, and if anything did you can simply just reinstall them
with your favorite package manager.

Side note: the so-called "ffmpeg" package in the repository is not
actually from the FFmpeg project:

Unknown since you did not include the line that shows all of the
configure options. Alternatively you could run "ffmpeg -encoders | grep

Although you ran "make install", and assuming opus compilation was
successful, it didn't install anything to your system (it "installed" to
~/ffmpeg_build) so it won't do anything if you leave it. If you want to
get rid of all traces of just the opus stuff one method is:

$ cd ~/ffmpeg_sources/opus
$ make uninstall
$ rm -rf ~/ffmpeg_sources/opus

Thanks. It's certainly possible that something is incorrect or
incomplete, and I admit that I may not have tested all releases that the
guide claims to support.
