There have been 37 total failures in the last 7 days (recent failure log).
Affected platforms are:

Paul, could you please assign this to someone who can take a look?

Flags: needinfo?(padenot)
Whiteboard: [stockwell needswork]

Alastor, this is in your new code for HTMLMediaElement playback with the graph, can you have a look?

Flags: needinfo?(padenot) → needinfo?(alwu)

It seems a racy issue which happens between the graph thread and the decoder thread (MDSM), but I am not sure the reason yet. The failure caused by the assertion is here and the mAudioEnded would only be modified on the decoder thread (if we have an audio track)

When video notifies its output, the video track listener would check another attribute, which can only be accessed and modified on the graph thread (or the main thread if the graph thread is dead), in order to know if audio ends or not. If the audio has been ended, it would dispatch a NotifyOutput() to the decoder thread to let video track to drive the clock.

However, if audio has been ended, that means we should already notify the listener on the graph thread, which should trigger setting mAudioEnded first on the decoder thread.

I will go to enable debug log on the try server and see if I can get more information about how this failure happens.

Unfortunately, although I can reproduce once this issue on the try server, but on Android the moz log seems not showing. Per the analyisis on the comment10, I don't have a good explanation for that assertion faliure based on the current information I had. As this only happens on Android debug, I will go to disable it on that platform.

in Bug 1755075 we are splitting some of the mochitest media manifests- this makes it easier to see some failures and easier to run specific tests. This test is getting re-enabled, so it is possible this might be intermittent and start showing up again.
