Hi Forum,

I have a old thinkpad T61 with ubuntu installed on it (latest 11.04), and I have latest XBMC release installed as well. I have nvidia driver working fine, current version 270.29-0ubuntu1, I also set XBMC to use VDPAU, but XBMC still use ff-h264 to decode x264 movie. Is there any setting issue? Or does XBMC support VDPAU on T61?

Thanks

Noodle

VDPAU requires a card based on the G9x series cores.

According to the mythtv wiki and nvnews.net, the quadro chipset in the T61 (Quadro NVS 140M) should work with the VDPAU extensions. Have you set up an Xorg.conf file? Degug log maybe. Could be that XBMC isn't playing nice with it as well.

Wait, x264 not h264? Is it SD or HD?

*edit*

The Wiki Wrote:<vdpauscaling>true</vdpauscaling>

If it's SD content all is working as it should.

For scaling yes, but for decoding if the content is h.264 encoded, vdpau should kick in for decoding and ff-h264 should be bypassed.

BTW, x264 is an h.264 AVC encoder, not a separate codec.

I will check xorg.conf and try to get debug log once I get chance.

Thanks for taking time to look at this, BTW.

Check xorg.conf, nothing special.

in xbmc.log I found:

I'm thinking is it possible because there's no enough RAM allocated to video card? I have 2G RAM total, and I cannot found video RAM configuration in BIOS.

Thanks

VRAM could be an issue, have you also made sure that any compositing is disabled in your Xorg.conf file?

darkscout · 2011-05-09, 20:08

Get a bigger swap file. When my swap ate itself and wasn't working I was getting the same errors. I just made a 5GB file on my hard drive and did swapon /swapfile. Fixed all the problems.

Noodle · 2011-05-10, 01:33

Thanks, I will try this trick, were you fix it on T61?

Sorry, but increase swap doesn't help. I create a 5G file and use it as swap (I have 4G partition already). So total 9G swap still not using VDPAU.

Here is my xorg.conf file, nothing disabled. This laptop connect to a Dell 20" monitor, so should be two "Monitor', but I see only one. Could this be an issue?

Any news on this? XBMC Eden still not using VDPAU.

FernetMenta · 2012-03-28, 09:01

I had a brief look in the spec of a T61. 128MB video ram is not enough to get this working.

pumkinut · 2012-03-28, 18:46

Yikes! 128MB of VRAM, that's way low.
