User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:46.0) Gecko/20100101 Firefox/46.0 Build ID: 20160111180959 Steps to reproduce: Download https://people.mozilla.org/~rgiles/2016/sample.mp4 Try to open it in Firefox. Actual results: The usual "Video cannot be played" appears. Expected results: The audio should have started playing.
Note, I don't know if opus is working with MSE or fragmented MP4. Related bugs https://bugzilla.mozilla.org/show_bug.cgi?id=1240413 https://bugzilla.mozilla.org/show_bug.cgi?id=1267887
So this is a 'regression' in that the non-fragmented file used to play, even though we were targetting MSE in the initial implementation. Matthew, is non-fragmented Opus blocked for a good reason, or was this accidental?
It's a regression from bug 1240412. That added a call into MP4MetadataRust::ReadTrackIndex but only implemented the fragmented case, so now instead of using Stagefright's answer we MOZ_ASSERT(false, "Not yet implemented") and then return false.
Right, thanks for clarifying.

Comment on attachment 8794068 [details] Bug 1304820 - use stagefright instead of rust parser when rust parser fails to parse a file. https://reviewboard.mozilla.org/r/80692/#review79342 Looks fine, but maybe downgrade the NYI assert in the Rust ReadTrackIndex to an NS_WARNING.

[testday-20170217]The bug is not resolved it seems. Can't play video in Firefox Beta 51. OPERATING SYSTEM : Windows 10

I can verify that this has been fixed in Nightly 54.0a1. I tested on Ubuntu using Firefox Beta 52.0b3 and Nightly 54.0a1. https://people-mozilla.org/~rgiles/2016/sample.mp4 plays a song and does not display the "Video can't be played because the file is corrupt." message
