MP3 audio seems to be broken

[virtulis]

Hi,

I spent some time trying to figure out why a specific video wouldn't play (it plays fine over http, but not so much via webtorrent+videostream). Thought it had something to do with atoms and all, but it looks like videostream just has some problem with the mp3 track (reencoding with -vcodec copy -acodec aac completely solved the issue).

Sorry, I don't currently have an isolated test case so I'm just speculating. But if that's indeed the case then I think it should be documented.

Edit: yep, tried reencoding Sintel audio as mp3 and uploading it to https://instant.io - interestingly, it plays on the upload (seed) page, but not when opening the link in another tab.

Edit 2: ok, it seems to have something to do with the atoms, too.
