What Tim said.  How about dust in the case / overheating?  It is likely
this is a software problem in the kernel driver, but it is always
possible it isn't.  Trying an older kernel eliminates that possibility
if it works.

You can get older kernel packages here:
https://koji.fedoraproject.org/koji/packageinfo?packageID=8

and install them after downloading using the

dnf -C install [package names]

command in the directory where they are.

seems it's a regression.

Anybody use Radeon APU(Kaveri) - you probably experience the same problem - your HW UVD & VCE then consequently VDPAU (mybe VAAPI too)
is gone.
Kernel that brings UVD & VCE back(firmware loads successfully) is 4.11.8-300.fc26.x86_64.
4.13.x from f27 also carries this regression.
But even with 4.11.x to me seems Mesa has a problem for I do not have VDPAU. If you have something to chip in, help fix it maybe - bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1496833
