> John, please double check that you are actually correctly installing VDPAU.

Alright, I've just tried that and mpv seems to be waiting, no error in output
nor in dmesg, which should be as expected I guess.
Please tell me if you can think of any other thing I can test.


> That it's a kernel issue came to my mind as well, but we haven't changed anything on UVD in the radeon module in quite a while. So this is a bit unlikely.

I looked at radeon_uvd.c's history quickly and there were a few in the time
period I'd think of.
Based on the date I'd guess possibly either of the kernel commits on
2016-05-05, probably nothing later, and before is so far away.

Is amdgpu using the same firmware as radeon for SI? if not maybe that's another
option for the culprit.
