[SOLVED] Problems with video/media playback. High CPU load
On the machine which I set up recently I started having some problems with my cpu load, at least when playing media, for example watching videos on youtube. It sometimes gets really laggy and sometimes I can't even watch the videos on full screen, only lower resolutions work. The computer isn't the newest one, but I never had many problems and at least watching videos on youtube shouldn't be much of an issue.

Failed to open VDPAU backend libvdpau_r600.so: cannot open shared object file: No such file or directory so I figured it might be connected to a problem with my graphic drivers. So far I haven't done to configure my graphic card besides installing xf86-video-ati.
Do you have some ideas what I could do? Tell me if you need any more information.
Thanks for your help

Re: [SOLVED] Problems with video/media playback. High CPU load
Install mesa-vdpau, reboot and try again.

Re: [SOLVED] Problems with video/media playback. High CPU load
Kernel CPU usage is very high.
Probably some issues with graphic acceleration.
Consider installing proprietary driver for ATI (catalyst)

Re: [SOLVED] Problems with video/media playback. High CPU load
Next time you can try figuring it yourself, there's pkgfile to help https://wiki.archlinux.org/index.php/Pkgfile
You've got an error about a missing file: libvdpau_r600.so. Let's see if any package from the repos provides it
$ pkgfile libvdpau_r600.so
extra/mesa-vdpau:-)
