MediaSourceReader needs to override IsDormantNeeded().

Can you explain about how to try the play from the above page? Is b2g phone needs some modifications(like pref) to try the playback?

I tried the above page by using master flame. But I failed to do playback, although PC firefox browser can do its playback. Thanks.

I use this patch [1] to enable it on B2G.
BTW, due to the MediaElement "preload" is off on B2G, You need to press the play button.

Approval Request Comment
[Feature/regressing bug #]: MediaSource
[User impact if declined]: Idle YouTube videos won't release their decoders.
[Describe test coverage new/current, TreeHerder]: MSE mochitests
[Risks and why]: Without this change, the dormant stuff added in bug 1123535 won't engage for YouTube MSE videos, and so idle YouTube MSE videos won't release their resources when they are non-visible and idle. Sorry I didn't realise this wasn't on beta until now...
[String/UUID change made/needed]: None.
