Since we're not shipping MSE in Fx36, and we have Bug 1128357 in beta, I think we should disable dormant heuristic in Fx36.
Approval Request Comment [Feature/regressing bug #]: bug 1123535, shutting down idle decoders [User impact if declined]: Sometimes we'll not display the first or last frame of a video if the user loads the video in a background tab. This affects both MSE and non-MSE video. [Describe test coverage new/current, TreeHerder]: I saw RyanVM complaining about media orange earlier today, so maybe this was it... [Risks and why]: This patch turns off a feature, so we'll revert to the old behaviour we had in 36. [String/UUID change made/needed]: None.
Comment on attachment 8560355 [details] [diff] [review] Patch: Disable MP4Reader dormant heuristic I agree this seems safer. r=me.
