Isn't that the kind of correlation that should happen on our end, and
not rely on individual sites doing it, though? (which, in practice,
means one specific site)
It's (currently!) easier for YouTube to correlate the GPU info with the
particular problem (e.g. GPU decoder produces black frames) because
YouTube users can right-click on the broken video and select "Report
playback issue" context menu item. Mozilla only receives feedback from
bugs reported on Reddit or Firefox's "Submit Feedback" menu item buried
in the Help menu.
Soooo.. perhaps we should make Firefox feedback more discoverable by
adding our own "Report playback issue" context menu item on HTML5 video
elements. It could deep-link to the existing "Firefox makes me sad"
feedback form. If the "technical information about your browser"
collected by the feedback form includes the GPU info, then we can do all
the correlation ourselves without exposing WEBGL_debug_renderer_info to
web content.
HTML5/MSE video decoding was on the pre-release channels for a few
release cycles, but we didn't hit these GPU issues until MSE was on the
release channel. So we need better way to collect feedback from release
users. The "Runtime Hardware Testing" project that Jet just announced on
dev-platform will help.
