ReplayGain in m4a/mp4

[Lascaille]

Okay, how exactly do I format replaygain information in mp4/m4a files to make Audacious pick it up?
Because ffmpeg tells me that it's there, mp3tag tells me that it's there, winamp reads it, audacious manages to read the relevant metadata but doesn't get the replaygain info.
I'm using Picard, mostly, to tag and organise these files.

ReplayGain is not supported yet by the FFmpeg plugin of Audacious.
At least I didn't found any references for it in the source code.

@jlindgren90: Can you confirm this?

Sounds right

If I can figure out how to implement it, would you merge? (I'm not confident, but I'll look.)

Anyone is welcome to submit a pull request. We don't make promises in advance about what will be merged. It depends on the quality of the code.
