Details

I recorded a Gecko profile with the upcoming Raptor Youtube benchmark suite (bug 1548845) which is playing a 1440p60 VP9 video at 2X playback speed:

Due to known problems (eg. bug 1400787) I expect a lot of dropped frames, which also happen as the test reports. But what makes me wonder is that we do not have any drop markers in the recorded MediaPlayback threads:

As Paul mentioned this is most likely because the problems lay in GFX.

Anyway it would be great to also get drop markers added for those cases.

Priority: -- → P3

Bug 1578042 is adding those markers in the Compositor thread.
