The audio track has a .mp3 box in the stsd which we don't currently handle. The code is specified for Quicktime and it looks there is also an alternative way to signal it using an ObjectTypeIndication.

@andrewlewis can we expect any estimated time for beta-version of exo-player with the above enhancement.We are waiting for it.

@vishnuganta22 I don't have a concrete ETA for this yet, but the (unreviewed) patch is very simple:

1. Add TYPE__mp3 = Util.getIntegerCodeForString(".mp3"); in Atom.java.
2. Add a check for || childAtomType == Atom.TYPE__mp3 in AtomParsers.java.
3. Set the MIME type in parseAudioSampleEntry: else if (atomType == Atom.TYPE__mp3) { mimeType = MimeTypes.AUDIO_MPEG; }.

Thanks for the pull request, but we have already submitted this change internally. The feature should be available next time we push to dev-v2.

This should be fixed in dev-v1 and dev-v2.
