Comment 17 for bug 1424201

I'm on Fedora 23, ffmpeg and vaapi libs installed. Intel Sandy-Bridge hd3000. HW decoding with libva works in native apps.

Testing FF 45 nightly , in about:support I see : "Supports Hardware H264 Decoding No;"

Is there a way to test that ffmpeg is in fact used ? And for for HW accel?
