Comment on attachment 8571088 [details] [diff] [review] GetOutputStreamInfo() after each SetOutputType() Approval Request Comment [Feature/regressing bug #]: mp4 media [User impact if declined]: Uncertain. Requesting approval based on the possibility that this might help with shutdown or video playback hangs tracked in bug 1129455. [Describe test coverage new/current, TreeHerder]: There are some web platform tests and mochitests, but I don't know whether or not any would or what exactly would trigger the scenario addressed here in handling responses from OS libraries. [Risks and why]: simple patch, so low risk. [String/UUID change made/needed]: none.
Comment on attachment 8571088 [details] [diff] [review] GetOutputStreamInfo() after each SetOutputType() Approval Request Comment Adding request for beta to request in comment 5. Bug 1129455 is a big enough issue and the risk here is low enough that this seems worth taking in the hope that it might help with Bug 1129455.
