I heard that maybe upgrading to a newer version of FFMPEG than what's included in Debian by default might solve some of my problems. But I've had bad experiences with upgrading packages like that, sometimes packages depend on explicitly an older version of another package.
I can run
apt-cache rdepends ffmpeg to see which programs depend on FFMPEG in general, but that doesn't tell me which ones might break when I upgrade it.
How can I see which packages depend on this specific version of FFMPEG? Is this even saved anywhere or just a complex property of each program?
Bonus: If upgrading messes something up, can I go back?
