1166416 - [music] Move audio playback to the "backend"

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::Music, defect)

Description

[Jim Porter (:squib)]

As part of the music player refactoring, we'd like to move the audio playback and all of the other related code into the "backend" (read: a separate iframe). This includes the actual <audio> element, remote control handling (bluetooth and lockscreen/tray), and playlist advancement. The UI will then send/receive messages from the playback backend.

Nice work man! Looks great! I left a few minor nits/comments on the PR for you to look at.

Kevin - since this is resolved, could you do a check on the music app for any regressions?  According to Jim, there is a fundamental change in how the playback queues are being handled, so perhaps we could try out how it handles multiple music files.   I'll check it out as well.

Adding qawanted to thoroughly test around any areas that could be affected by this landing. See Comment 4.

I spent some time listening to mp3, mp3 320, m4a and flac files on both the Aries and Flame devices with no unexpected errors.  While listening to the files I used headphones/no headphones, interrupted the songs with calls and radio (on flame), and let the albums play in completely.

Note: Bug 1193498 has been written about downloaded mp3 files from the browser not being recognized, but I'm not sure if that would be related to the changes that have been made here.
