mp3gain is kind of destructive, right?
This is imho a bit problematic by itself and possibly even more so when
audio is intermixed with a video. No idea how hard it is to extract
audio from a container and later recombine audio/video into a container,
but something like that might be necessary.
Nicer would be 'real' replaygain, by which I mean the concept of just
changing tags and adjusting the audio at playback time.
In any case, I haven't heard about anything like that for video, but it
would be really nice.
