Totem screenshot (of the 20th Century Fox intro)

Totem cannot correctly play MPEG videos with Mesa on a range of AMD GCN cards. The videos are tainted reddish (see screenshot).

I'm using Mesa 18.2.5 (previously 18.1.9, same problem) from Debian/testing with Xorg 1.20.3 on a Radeon RX 560 (POLARIS11, DRM 3.26.0, 4.18.0-2-amd64, LLVM 7.0.1) device, with up-to-date firmware and Linux kernel 4.18.10 (open-source AMDGPU driver).

I've reported this as Totem bug https://gitlab.gnome.org/GNOME/totem/issues/241#note_370403 and am reporting it here because the Totem maintainer is convinced that it's a Mesa problem.

Looks like it's a clutter-gst bug, not handling 10 bit per component RGB formats correctly.
