--- Comment #4 from yuli...@mailbox.org ---
I just freshly installed the new Fedora 26 and compiled kaffeine from git. In
my case there is no difference between git and the last version, but it is
pretty smooth most of the time now. This has nothing to do with changes of
kaffeine, though.
The problem was the VDPAU package, that should actually accelerate the video
processing. Because after installing the package mesa-vdpau-drivers and enable
it via "$ export VDPAU_DRIVER=r600" (known bug in fedora, see e.g. [1]), it
starts stuttering. After removing the package it works okay again. Although all
4 cores are at ~100%.
Maybe also other changes of the new system are relevant.
So it seems not to be a problem of kaffeine alone, but more like a problem of
VDPAU. Or the use of VDPAU of libVLC when the used codec is not supported.
VDPAU on my GPU does not support H.265. But as VDPAU development seems not very
active any more and my hardware is also relatively "old", probably it's not
worth to investigate further.
Thanks!
