1. Run a debug build with XPCOM_MEM_LEAK_LOG=2 2. Load the testcase 3. Quit Result: trace-refcnt reports leaked MediaStream and other objects.

The Media Recorder get the media stream object without tracks and enter recording state. I will fix it.
FWIW - this is good candidate to get a mochitest with btw. You could just create a test that models the exact test case included with an additional check that the InvalidStateError fires when calling start a 2nd time.
I will let media recorder throw the InvalidStateError exception when we got this kind of source. BTW, correct the comment 2, now it failed on principal check (no source can be checked) and throw security error without destroy the TrackUnionStream object, this unclear message would confuse UA.
Summary: MediaRecorder leak → Media Recording - memory leak when record a media stream without any tracks
patch for this bug, also include the test case.

(In reply to C.J. Ku[:CJKu] from comment #12) > bug 924724, which is koi+, depends on the change here. Need to uplift this > patch That shouldn't influence if this bug is a blocker or not. What you need to do on bug 924724 is build a branch-specific patch to fix the issue independent of this bug. I don't think this bug is a blocker either - it's not a likely use case a developer will do & memory leak impact isn't critical.
blocking-b2g: koi? → -
If the branch-specific patch ends up being "roll these changes into that patch", it would be preferable to just land these changes under this bug number. Also, we have a lot of historical precedent for "blocks a blocker" approvals.
