Hello everyone,

after I read that that XBMC will support CrystalHD accelerator cards I bought on from ebay (and a miniPCI-E to PCI-E adapter) und installed it into my Asus Barebone. I compiled the drivers, the lib and XBMC following an instruction I read in these forums (http://forum.xbmc.org/showthread.php?tid=66650&page=2) and everything went fine. Under settings I was able to switch the render method to Broadcom, but now I have only about 12fps to 18fps on 720p content. I run the latest (as of today) XBMC SVN version and, use the crystal hd driver from the git repos at github and my OS is Ubuntu Karmic Koala. I hope someone can help. I am eager to try out 1080p on my box!

Thanks in advance

Try out the current svn build in the PPA, that one have been stable for me at least.

I'm also using ubuntu 9.10, and the git drivers.

sudo add-apt-repository ppa:team-xbmc-svn
sudo apt-get update
sudo apt-get install xbmc

Shouldn't be a need to set renderer to crystalhd - just leave it on auto and it will use it when needed.

When do you get the stuttering? Is it when it first starts playing? What kind of materials are you using?

You need to check that crystalhd is actually being used. If xbmc can't load it (for what ever reason) it will kick back to software rendering.

Thanks for your answers. The PPA version has the exact same problem. The movie doesn't exceed 20 fps. When I look into the details where I can see fps and so on I see something like "dc:bcm-h264" in the second line. The low fps continues. I let a video run for about 15 minutes but no changes. All my HD vids are mkv. Some don't even show a picture but I read in this forum that this because of the PAR. When I set the decoder to auto. it still uses the broadcom. CPU load is also very low, so it definately decodes with the broadcom. Any other options I can check?

Once its up and running does skipping forward help at all?

COpy of a debug log may be of use.

dereulenspiegel · 2010-01-25, 19:58

Since the debug log is rather huge I better not copy and paste it in here. Here is the link to the file http://git.akuz.de/builds/xbmc.log
It is from one session where I started a trailer of big buck bunny. It ran with about 12-14 fps.

Can you copy the file locally and try again? (ie don't use a USB drive)

dereulenspiegel · 2010-01-26, 07:43

Sure, I will do it as soon as I am home from work.

Sorry for the late answer but my media center crashed. Literally from the board it was standing on. Luckily no expensive damage.
After the crash I did a clean install of Ubuntu 9.10 and followed the instructions to the letter. But still low fps count on all HD vids. I reuploaded the xbmc.log directly from .xbmc/temp via scp to my server. You can find it here http://git.akuz.de/builds/xbmc.log
I hope you can find my fault so I can finally watch my beautiful HD vids.

That's pretty old now, svn and re-build.

Ok, I checked the current source from this morning and rebuild the whole thing. But without success. The trailer of bug buck bunny still runs at only about 12 fps. I uploaded the log of it to http://git.akuz.de/builds/xbmc2.log I hope that anyone can see from this where the error is.
