As stated in the title, if I run mplayer from the CLI as follows:

Code:

mplayer -ao alsa:device=hw=0.3 -ac hwdts -vo vaapi:gl -va vaapi <file>

I get 5.1 DTS and tear free video with minimal CPU usage.

Playing the same MKV file in XBMC I get some tearing, high CPU usage and stereo sound. The question is, how do I get XBMC to pass the options through to mplayer?

The graphics are ATI Radeon HD 4200 (785G chipset).
Currently I'm running Ubuntu 10.04 server (Lucid Lynx) with Catalyst 10.4.

I have tried the following in guisettings.xml for sound:

Code:

<audiooutput>
<ac3passthrough>true</ac3passthrough>
<audiodevice>plughw:0,3</audiodevice>
<downmixmultichannel>false</downmixmultichannel>
<dtspassthrough>true</dtspassthrough>
<mode>1</mode>
<passthroughdevice>plughw:0,3</passthroughdevice>
</audiooutput>

But get an "error initializing audio device" message on the screen and no sound. I get stereo if I switch back to Analog but clearly this is no use.

Just reinstalled from the XBMC-Team repo, I guess this means I'll have to rip that out and take my chances with SVN.

Still happy hear any suggestions for the audio issue.

Turns out the sound issue was a typo. Should have been plughw:1,3.

Hopefully I can get VAAPI sorted with SVN and then I'll be set.
