Attached file testcase
With: user_pref("media.mediasource.enabled", true); this testcase causes a shutdown hang with 100% CPU use. Looking at the sample, I guess the "Media State" thread can never shut down because there are always more events for it?
Attached file hang sample
I used Activity Monitor to get a sample of Firefox Nightly during the hang.
Summary: MediaSource causes shutdown hang → MediaSource causes shutdown hang ("Media State" thread)
The testcase in bug 975782 is a superset of this testcase.
Blocks: MSE
No longer hangs. Unsure which bug fixed this as there have been many changes since the bug was filed. Added the testcase to crashtests to catch future occurrences.
