Click on the video to start playing it. The web process will hang.

However, web process hangs when i scroll on most twitter feeds that show some videos. i suspect it's related. It did not happen with webkit2gtk 2.22.7 in debian/sid.

I removed gstreamer-vaapi from the GNOME runtime and now it works fine, so it's surely caused by gstreamer-vaapi.

Could you remove gstreamer-vaapi and see if that fixes it? I bet the video-related hangs and other performance issues are all caused by -vaapi.

[Jérémy Lal]

I don't have the gstreamer-vaapi package installed, so we might have separate issues. Could libav be a problem ? Or gst plugins-bad, -ugly ?

[Michael Catanzaro]

I don't know. You should report a separate bug; I'm almost certain it's a separate issue if it's not caused by gstreamer-vaapi.

Please provide a non-geoblocked test-case.

[Michael Catanzaro]

I don't have one.
