I think this has something to do with recent Android changes.

> I think this has something to do with recent Android changes.

 Couldn't see how remote decoding would cause the problem. The log below shows fetchWithXHR() took > 5 minutes to load data [1] and threw error even before appending data to source buffer.
 Looks like bug 1324491 have the same symptom too.
 
 Is there log for XMLHttpRequest processing that can be enabled to help investigating why it took so long?

The logs are dumped when the test case times out. So the timestamps are not correct.

 Logcat shows some decoder error message. Will continue to investigate.
Duplicate of this bug: 1324491
The remote decoding process crashed because of a race condition that ICodec.flush() was executed between ICodec.dequeueInput() and ICodec.queueInput().
Assignee: nobody → jolin
Besides the problem in comment 8, there is another issue in RemoteManager.waitConnection(): when serivce is ready and onServiceConnected() finished before latchCreation [1], it will be blocked for 5s.

[1] http://searchfox.org/mozilla-central/source/mobile/android/base/java/org/mozilla/gecko/media/RemoteManager.java#99
Also observed that sometimes 'SimpleTest.finish.bind(null)' [1] doesn't invoke SimpleTest.finish() and causes time-out. Directly calling it seems fix the problem.

Never mind. Turns out that's a mistake in my try push.

Bug 1324530 - part 1: add method to AsyncCodec for resuming receiving input buffers after flush().

Can you move the comment on its own line on top of it?

Can't we just use resumeReceivingInput instead and implement it there?

The crashes were in fact caused by dom/html/reftest/bug1228601-video-rotation-90.html.
In that test, the SW H.264/AVC decoder failed to decode input samples and trigger a bug in Codec.InputProcessor that EOS sample are sent to SamplePool to be recycled and cause NullPointerException at [1].
