Description Richard B. Kreckel 2018-05-17 21:23:57 UTC 
Totem 3.26 is basically unable to play MPEG-4 or H.264 Videos on AMD graphics cards. It hangs, lags, and uses almost all available CPU resources.

It's interesting that this does not seem to be a GStreamer bug. (I'm saying that because gst-launch-1.0 -v playbin uri=file:///Movie.avi does not have problems playing the videos.) Also, MPlayer is always able to play the movies at high resolution (4K) with moderate CPU usage.

I'm using X11 (Debian/testing) and tried any combination of Mesa 17 or 18, Linux 4.15 or 4.16, amdgpu.dc=0 or amdgpu.dc=1. I've tried various AMD graphics cards: GCN 1 (Tahiti), GCN 2 (Bonaire) and GCN 4 (Polaris11). The result has always been negative.
