I see what you're doing there. Clever. Unfortunately, that kind of talk is exactly what brings projects like this one the wrong kind of attention. Piracy has nothing to do with the development of this project, and it's probably best to avoid inadvertently linking the two.

I haven't read this thread extensively, but is jerky playback on 8300 (and probably all 8xxx series cards) a known issue with VDPAU? If so is there a ticket?

So, I have the new Mini. Will this work fine? I have the cheapest one with 1gb RAM. If so, is there a live cd version?

It is possibly related to XBMC running like poop on 8200's, however i strongly doubt that playback will be jerky on all 8000 series cards.

do you mean just with vdpau?

i mean XBMC runs badly on 8200's at full screen, even the GUI only displays at 30fps. I have a patch thats around to help out though.

The card should be capable of fullscreen 1080p using VDPAU imo.

Yeah I've read plenty of places that reference he 8300 being more than sufficient. I guess that patch will make its way into the linuxport branch at some point? I'm already updating from svn of linuxport and smoothvideo on a daily basis... not sure i want to keep up with a third... ha

Just for the sake of education, could you explain what the 8200 is doing 'wrong' and how the two lines of code difference fix it?

I have the exact same issue. I'm running a Asus M3N78-EM motherboard with a 8300 onboard chipset. The XBMC GUI runs really slow (I'd guess around 20fps), and playback of movies either hangs X11 or is extremely jerky / broken.

I tried the latest version of MPlayer with VDPAU and with xorg.conf "Composite" "Disable" it runs flawless everything I've thrown at it - 1080p stuff of course.

Once you get used to sharpening effect, videos look shite without it :mad:

is that a vdpau filter that is usable in xbmc?


- SpaceMonkey - 2009-04-30 08:51

Yes :cool2:

The link is not valid.

I have 9.04 beta1 installed. I can say 1080p playback with VDPAU for 8100 (possible nvidia 8x00 cards ) works as long as I start XBMC up in auto resolution and setting the cpu frequency to 1.8G HZ.

To enter full screen you need press "backsplash" after xbmc started.

To do this automatic I wrote a small python script to
* start xbmc
* send the "backsplash" key as an event
* setup the min frequency for cpu scaling

scripts can be found here:

What is your experience with 720p videos?

Maybe something is wrong in my settings, but I get choppy playback on all my 720p H264 videos over HDMI with my 8200 IGP on my full HD TV. Auto resolution startup and performance mode (cpufreq) make them watchable, but not fully enjoyable, and CPU (5200+) usage is never lower than 50% according to 'top'... Could this be due to the scaling up from 780p to 1080p? 'High quality software upscaling' is completely disabled (DVDs were unwatchable with this on) and adjust refresh rate is disabled.

I am on the same motherboard. I got it for the 8300 which should be fully capable of 1080p over hdmi, even the killa sample.

Fortunately (and I really, really didn't realize it at the time...) I accidentally built my computer fast enough to decode 1080p in glsl/software... only drop about 70 frames on the killa sample... other 1080p sources work great.

Still, it kills the cpu and once I have other software running on this thing all the time (as I fully plan to do) there's definitely going to be an issue. CPU at 5%-25% while watching 1080p should be fully possible... It seems to be improving with each driver release but maybe that's just wishful thinking on my part...
