Project Member Reported by wychen@chromium.org, Oct 25 2016 
According to the flakiness dashboard, MediaSessionTest in content_shell_test_apk started to crash recently.

https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=content_shell_test_apk&tests=org.chromium.content.browser.MediaSessionTest

Some example output:

I saw the tests hit a DCHECK() in VideoRendererAlgorithm:

C42GC:  10-25 17:29:36.748 21449 21476 F chromium: [21449:21476:1025/172936:3026859401:FATAL:video_renderer_algorithm.cc(318)] Check failed: frame_queue_[last_frame_index_].drop_count <= frame_queue_[last_frame_index_].render_count (2 vs. 1)

Sending to Dale for triaging.

Comment 2 by dalecur...@chromium.org, Oct 25 2016 

Hmm, thought I just fixed this, not sure why it's suddenly started flaking.

Comment 3 by w...@chromium.org, Oct 25 2016 

Btw, an EME test needs to be reenabled when this is fixed  http://crbug.com/655630
