Bug description:
Totem uses dramatically higher CPU than any other video player.
Example 1: software playback under Gnome Shell Wayland:
totem: 120% (but drops to 80% in Unity7)
mplayer: 40%
vlc: 40%
[all are using ffmpeg for decoding]
Example 2: hardware-accelerated playback under Gnome Shell Xorg:
totem: 11%
gst-play-1.0: 3%
[both are using gstreamer-vaapi for decoding]
Since the decoding libraries are theoretically the same it sounds like
totem's performance problems might be in its rendering path.
