It looks like those only cover DTS extensions, which we all
mark s AV_CODEC_ID_DTS. Is the DTS base layer 'mp4a'? I don't
have a source on what is correct to do here, or how to fit it
in (since this seems to imply DTS should have a 1-to-N mapping).

Does copying these work post-patch? FATE passes, but we probably
don't have stuff like a DTS-HD-MA-in-MP4 sample.

(I changed the EAC3 entry locally but have not sent a new patch
since I'm not 100% sure about the DTS stuff.)
