Hello.

I just got two ASRocks delivered to home. So thought I'd try them out. I have before this been running XBMC on a C2D @ 3GHz doing all decoding on the CPU instead of GPU. Whilst this has been working great I thought I'd go for something smaller.

The basic setup is to ouptut 1080p with VDPAU video decoding and to sync it at 24Hz when doable.

So. First off I installed a Live version of 9.04. Updating the drivers to the latest 185.xx, and got VDPAU working. I only play contents off SMB mounts. Whilst playing works fair stopping the video is another matter. It *always* results in an XBMC crash / reload.

I have located it down to this behavior when enabling "Auto adjust refresh rate". Having this unticked does not cause the problem. The video syncs at 24Hz during playback. Turning off VDPAU also resolves the issue. However playback drops to ~11FPS for 1080p contents

So on the other ASRock I installed a Hardy 8.04 server, switched to a -generic kernel, built the Nvidia stuff required and updated ALSA. Got it working. And it's exhibiting the exact same behavior.

I see that all guides recommend to set the menu resolution to 1080x1920@24Hz per default. This is not desirable for me as I experience menu lagging whist having this mode. And whilst it seems to be the combination of VDPAU + auto adjust refresh rate and the fact that it only appears while VDPAU is activated I would presume it's a bug.

The relevant part of my xorg.conf:

Code:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"

#Workaround for visible X cross
        Option "HWCursor" "false"

#Adjusting general font size in X
        Option "UseEDIDDpi" "false"
        Option "DPI" "96 x 96"

#Regarding following option: Without this Auto Adjust Refresh Rate
#has no effect. Probably related to others setting the 24Hz mode
#hard in the XBMC menu.
        Option "FlatPanelProperties" "Scaling = Native"

#Disabling TwinView for 24Hz
        Option "DynamicTwinView" "False"

EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
        Modes   "1920x1080"
    EndSubSection
EndSection

XBMC Versions tested:

• XBMC Live 9.04
  
• XBMC 9.04 built from source (for VDPAU enabled under hardy)
  
• XBMC latest SVN as of yesterday
  

More filled out surveys from the "Posting problems in a useful manner":

Linux Distribution and Version: Ubuntu 8.04 & 9.04 (Live 9.04.1) all 32-bit
Architecture: Intel ATOM 330 1.6GHZ ION platform
Install Method: PPA, Source, Live included version
SVN Revision: 9.04.3+svn23164 (for the SVN attempt I did)
Detailed Instructions to Reproduce the Problem:

1. Enable VDPAU and Auto Refresh rate in combination with my xorg.conf settings and a menu of 1080p at auto detected rate
2. Play back contents over SMB
3. Stop content, XBMC crashes.

Playback Problems:

Core dump: Did actually Not find a core dump from xbmc. This was the 9.04.1 built with debugging etc. (ran ulimit -c unlimited before aswell)

If you got a suggestion for an applicable workaround other than setting system menu to a hard 1920x1080@24Hz I'd love to hear it! :-)

Thanks for the notice. Hope it's sufficient.

Are in wrong section

I have almost identical setup (ZOTAC ION330, XBMC Live 9.04.1) and I see exactly the same problem. I only added "DynamicTwinView" "False" to my xorg.conf (in the correct section, of course) to make auto refresh rate work. I've also observed that the crash only occurs if a video was played using vdpau, some old PAL mpeg2 which also triggers a mode change but is decoded in software doesn't lead to the crash.

I compared xbmc.log for both cases and found the following difference, notice the mode change via xrandr and then the bad mutex:

Code:

The log ends there suddenly because of the crash. In comparison, correct termination of the player when vdpau isn't used looks like this:

Its been fixed on SVN for several days - give it a shot.

[kolja]

Thanks. Installed 9.04.3+svn23481-jaunty1 from ppa.launchpad.net/team-xbmc-svn and the crash is gone. However, now the performance for h264@1080p24 playback degraded significantly. With 9.04.1 it had worked flawlessly, but this versions sometimes drops down to 20fps with massive audio desync. Also the CPU load has gone up to around 50% on two cores. Did I miss something?

[bobo1on1]

You're not still on the 180 driver series by any chance.

[kolja]

Yes, I was ... with 185 it's back to normal. Thanks for your fast help.

[mhakali]

Thanks. Installed 9.04.3+svn23481-jaunty1 from ppa.launchpad.net/team-xbmc-svn and the crash is gone.

Upgrading my XBMC was my remedy to the problem aswell.

Are in wrong section

No, they are not. They are nvidia options in the Device section for nvidia.

[vikjon0]

No, they are not. They are nvidia options in the Device section for nvidia.

I do not know NVIDIA or Linux like you. I have just followed the instructions on this and other forums.

Put the lines in any secton you want. My Asrock ION 330 is working with autorefreshrate and I though you wanted some suggestions.

1. I think you missed the point that this was a reproducible bug that was fixed in a SVN

2. I think you missed the point that both I and the other person got a remedy from upgrading

And for the placement; both probably works placement wise. But since you said it was wrong I thought you would find it nice to be correctly informed so that you don't think this is the problem in the future again. Some one else may actually believe that you know what you are saying holding back the debugging because of it. All in all you will slow down the solution process.

I did/do want suggestions, I do not however not want guesses. Refer to the nvidia manual for options and how to apply them.

[vikjon0]

Ok, fair is fair. I tested to move the lines to device and it still works. I guess it is possible to set these option per card or per screen.
