It appears we've reached a milestone today: totem's CPU usage is no longer significantly higher than gst-play-1.0 --videosink=clutterautovideosink (or glimagesink)
If you compare it to mpv though, totem is 2-3 times heavier still. However profiling totem and gst-play-1.0 today seems to suggest that is due to: (a) Lack of DMA-buf support in clutter-gst (https://bugzilla.gnome.org/show_bug.cgi?id=759209) (b) General complexity of GStreamer I think the remaining piece here is to get (a) fixed. However before that will ever work for us, apparently gstreamer-vaapi needs additional fixing so that it does not conflict with the patch we're using for Ubuntu right now: https://bugzilla.gnome.org/show_bug.cgi?id=784369#c12 It sounds like this remaining piece (a) is in progress with upstream. And (b) doesn't look as significant or like a realistically solvable problem any time soon. So I think I'm done here, unless I can help upstream with (a)... ** Bug watch added: GNOME Bug Tracker #784369 https://bugzilla.gnome.org/show_bug.cgi?id=784369 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to totem in Ubuntu. https://bugs.launchpad.net/bugs/1698282 Title: Totem uses dramatically higher CPU than any other video player To manage notifications about this bug go to: https://bugs.launchpad.net/clutter-gst/+bug/1698282/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
