Don't mark the last video frame produced by MediaPluginReader has having duration of $mediaEndTime. It should be $mediaEndTime-$frameStartTime. Regression from Bug 930829.

Since this was a regression from Bug 930829 which is in Firefox 27, this probably should be uplifted to Aurora and Beta.

Landed for 32. https://hg.mozilla.org/integration/mozilla-inbound/rev/81f84748793b We should uplift to Aurora 31 and Beta 30. This isn't worth a chemspil, so not noming for tracking 29.

ni? myself so I don't forget to request uplift...

Comment on attachment 8420730 [details] [diff] [review] Patch [Approval Request Comment] Bug caused by (feature/regressing bug #): Bug 930829 User impact if declined: MP4 videos on android won't end properly, once playback reaches the end they will continue to "play" blank data for the duration of the video again. This means the UI looks weird, and the media reports being twice it's actual duration. Testing completed (on m-c, etc.): Been on m-c for a few days, verified fixed by QA. Risk to taking this patch (and alternatives if risky): low. String or IDL/UUID changes made by this patch: none.
