--- Comment #5 from Mauro Carvalho Chehab <[email protected]> --- (In reply to yulinux from comment #4) > 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. Yeah, HEVC support is restricted to a few GPUs. > 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! > > > [1] https://bugzilla.redhat.com/show_bug.cgi?id=1305699 Thanks for testing and providing the above information. I added a summary of the above at README.md, with will hopefully help others that may have troubles setting vdpau: https://commits.kde.org/kaffeine/a16fdee4de0f007874cd9aff3fbe93731e8473f9 README.md: Add an extra section about vdpau settings Properly setting vdpau may reduce CPU usage on Kaffeine. So, add a chapter describing how to do it in order to workaround for a few known issues. -- You are receiving this mail because: You are watching all bug changes.
