[MPlayer-users] mplayer-vaapi

I have been attempting to get my laptop to play high definition video using 
libva, xvba-video and mplayer-vaapi from splitted-desktop.

Although I have had some limited success, I am frustrated by the fact that 
although vdpau has been built into mplayer for some time (I'm running it on 
the desktop on which this is being written!), the ati equivalent - vaapi/xvba 
- seems to be being ignored!

Here are some details.......

Computer: Acer Aspire One 721
Gfx: Radeon 4200 (RS880)
Driver: Catalyst 11.5
System: Slackware64 13.37

This combination plays videos shot on my personal hi-def camera perfectly But 
if I plug a second display into the computer (either via HDMI or VGA), mplayer 
immediately crashes with the following error: "MPlayer interrupted by signal 
11 in module: preinit_libvo".

If I build the latest libva-0.32.0-1+sds2, and rebuild mplayer-vaapi, then it 
ALWAYS crashes immediately on opening with the same error, even when only the 
internal display is in use!

By the way, when rebuilding libva, it appears to be imperative to remove the 
existing version BEFORE compiling the new version, or else everything appears 
to link to the existing version!

vainfo kept complaining about not being able to find 0.31 after I upgraded to 
0.32! It was only by removing 0.31 completely before compiling 0.32 that I 
could get it to work!

I have tried to apply the splitted-desktop patches to more recent versions of 
mplayer, but this is proving very difficult! Ffmpeg has now moved to git from 
svn, and mplayer is about to do the same, but the script supplied with 
mplayer-vaapi relies on svn. ALthough some of the patches apply, I get a lot 
of "patch failed" errors!

Does anyone know how to get around the signal 11 error, or how to apply the 
patches to more recent versions?

Better still, does anyone know how to persuade the devs to look at vaapi/xvba 
more closely?
