Kodi Community Forum - Poor performance on Radeon HD 6450

Recently I reinstalled my HTPC in order to upgrade some hardware and the version of Fedora I was running. Anyways, after several days of searching and trying different solutions I can't seem to get clean 1080p playback on my machine. Framerate seems really low (around 20 fps) and usually things start off with a audio lag. I'll try to include as much information as possible but please let me know if I'm missing something.

OS: fedora 20
Kernel: 3.13.10-200.fc20.x86_64
Host CPU: Intel® Atom™ CPU 330 @ 1.60GHz, 4 cores available
GPU: Radeon HD 6450
XBMC version: XBMC 14.0-ALPHA1 Git:20140418-134b6d4 (compiled Apr 19 2014) I should note here that I originally started out with the rpmfusion version but had the same issues so I tried compiling from source.

Here's my debug log http://pastebin.com/FDaACPJB

And I have the latest Catalyst Driver installed http://support.amd.com/en-us/download/de...x%20x86_64#

Any suggestions or help would be greatly appreciated!

there is no hardware video decoding support with catalyst. See the radeon OSS vdpau howto(for ubuntu) on top of this forum.

@wsnipex Thanks for the response.

I read through the instructions and from what I can tell, I should be good. My card is UVD 3 I have the same packages installed ( at least the fedora versions) and I'm running the latest "Installation of the team xbmc repository with mainline builds" to which you can see above in my original thread. Am I missing something that's staring me right in the face?

Debug Log will tell and also provide the other output the OSS howto wants.

yes you are running catalyst/fglrx

So if I'm running the right drivers and XBMC version then do you have any idea why I would be getting such poor performance? Also is there anything I might be able to try to workaround the issue?

If it helps here's the latest Debug log with the advanced settings suggested from that thread http://pastebin.com/ZmnZ5ugp

Obviously I still didn't make myself clear, so I'll try again:
There is NO proper video acceleration with fglrx! You must use the OSS radeon driver and mesa >=10 with vdpau support.
