Known issue with e10s/sandboxing (GMP/OpenH264); don't have the bug # off the top of my head on a Friday night
Not sure what the exact cause is - I see this on an inbound build I made today on Mac (but not on Linux; of course sandboxing is very different between platforms. ./mach mochitest-plain --e10s dom/media/tests/mochitest/test_peerConnection_basicH264Video.html
Can we please get a test for this into automation so that when it's fixed it doesn't recur?
Here's what I suspect is happening: We're attempting to initialize the GMP sandbox when the content process is already in place. Neither this kind of operation nor the reverse will ever work (be allowed). The only solution is to proxy the loading of OOP plugins through the main (chrome) process. This will not be easy, and I expect it will be several months (at least) before the work is finished. I seem to remember that people are already thinking about this. I'll try to find a bug number. In the meantime, GMP sandboxing simply isn't going to work in e10s mode.

Bug 1057908 is about proxying the creation of GMP plugins through the main process.
See bug 1076385 for content process sandboxing on the Mac.
