Hello all. I have problems when i try to watch 1080p on Fedora 20. With or without h/w acceleration cpu usage is ~70% on all 4 cores. I have the default ati drivers and i am up to date. My specs are:

Cpu: Intel 2500k.

Vga: Ati HD 7850.

Mind that i installed fedora recently so it maybe me due to something i did wrong. If you need me to input any info from terminal please say so. Thx in advance and sorry if i haven't provided enough info.

This is some kind of normal. I mean, you are watching 1080p and a value of 70% on CPUs is not considered as something extraordinary.

If you want to transfer the weight in AMD/Card , you can try two things.

  1. Install the closed source driver . See this guide on how to. It's a bit tricky, but if you pay attention you can handle it.

  2. For the open source driver, try to Install and use VDPAU support.

Though I cannot test this, I don't have an AMD video card, I guess it will be working.

sudo yum install libvdpau-va-gl libva-vdpau-driver libvdpau

After the succesfull installation, open VLC or SMPlayer and change the settings to point to VDPAU acceleration.

SMPlayer example

Flash Player(Streaming Videos through adobe flash player) doesn't support VDPAU acceleration.

Thanks for this post. This is the first I've heard of VDPAU.

I'm using AMD Catalyst (currently using the Fedora 19 packages from RPM Fusion for my Fedora 20 system), and most things run a bit better than with the Radeon driver, even though Radeon has come a long way recently.

If VDPAU can improve Radeon performance, I'm all for it.

Well, vdpau is currently under development and testing. It works fine under my Intel card though. It reduces the CPU load about 30-40% , but my Intel card is not very powerful to support 1080p video. So, video playback is a bit sketchy.

Another good player available from RPM Fusion is mpv. To use vdpau acceleration, 2 lines needs to be added to ~/.mpv/config:
