XBMC for Linux VDPAU support (ongoing development in an separate SVN branch)

**motd2k** · 2009-02-15, 20:14

First of all - this is a work in progress. Code will be changing frequently and as such this branch may not always be functional.

VDPAU is a hardware video decoding library, provided by NVIDIA. Currently it only functions on their 8xxx and later GPUs.

Current state-of-play:
h264 decoding
mpeg1/2 decoding
VC1 decoding (xbmc currently seems unable to play WMA3 though)
Hardware deinterlacing
VDPAU post-processing

Instructions:

Make sure you have the latest NVIDIA driver. This link will point you in the direction of the current version.

PHP Code:


			
cd ~ 
svn co https://xbmc.svn.sourceforge.net/svnroot/xbmc/branches/xbmc-vdpau xbmc-vdpau 
cd xbmc-vpdau/XBMC 
./configure 
make

To run, type...

PHP Code:


			
./xbmc.bin

WOW
Ordering ASAP a sufficient video card

Are there any xbmc-specific minimum requirements to this card except VDPAU compatibility? Or will the cheapest VDPAU card do the trick?

Good work!

What's the news on the color and other various syncing issues using the VDPAU renderer?

but yes it currently has small sync issues (for me) and also doe snot play avi files at all (seg fault) so its not really a main xbmc use thing yet like motd2k says

Very interesting, I was wondering when someone would start this (sooner than I expected). Quick question, though. When you say decoding not enabled, does that mean this version cannot decode - that is to say, play - mpeg12/WMV, or merely that they are not decoded using VDPAU (so using the cpu, instead)?

Again, thanks for the start on this!

This branch will currently (15-FEB-09) only play h264 files. Obviously thats high on the priority list.

EDIT: 16-FEB-09 -- Should now play most files that XBMC would play before

Very nice! I just tried it with my GeForce 9500 GT/AMD 5600+ X2 and it seems to be a vary good start!

Using the cloverfield sample, i think it dropped only 1 frame, with both CPU's sitting at about 16%. On Atlantis, the CPU's go up to about 80%, dropping frames the whole way.

I also tried a BD Rip of National Treasure 2, which caused more problems than the cloverfield one, but a very significant and noticable improvement over the Atlantis build. With VDPAU, it used the same 16% on both CPUs, and on Atlantis, one CPU was pegged at 100%, and the other at about 60% (strange?).

Finally, 2Mbps/H.264 high profile DVD rip of X-Men 3 produced flawless results, at the same 16% CPU, while Atlantis gave flawless results with about 40-50% CPU.

There were some audio syncing issues in all but the X3 video, but that is an already known issue, so i didn't pay much attention to it. I did not notice any colorspace issues, but again, wasn't really looking for them.

In all, I am very impressed! I realize this is pretty new stuff, but I thought I would congratulate the authors and thank them for their awesome work, and share my findings.

Now supports accelerated MPEG1/2 and VC1.
Fallback to GLSL for formats which VDPAU doesnt accelerate - meaning that the branch will now playback all formats once more.
Changed the code to default to having the renderer set to VDPAU for machines with the libs installed.
Ability to change the renderer dynamically within XBMC

Just tried the new branch on my 2.93Ghz C2D with a 9500GT. It plays the killa sample absolutely flawlessly with roughly 25% total CPU usage; 15% CPU0, 10% CPU1. It also seamlessly fails back to software on formats unsupported by VDPAU. I didn't get a single crash and everything played, although compilation had a ton of warnings and whatnot. I'd even consider using this branch as my primary at this point, if we weren't directly cautioned not to do so. Great work!!

I know this is the linux forum but i just want to know is this going to be able to be ported to windows and mac?
