Xibo won't load - Failed to open VDPAU backend libvdpau_nvidia.so cannot open shared object file

Asked by matt

I cannot get Xibo to load under this configuration. ATI drivers are installed and working (It is a 5400 series card). I have got the splash screen to load, the client has a license, but will not play the schedule. The previous schedule has worked on a windows client and a similarly configured (but Nvidia-based) client.

Here is the information from the terminal. The splash screen has not loaded since a new schedule was loaded to the client.

Switching to new logger

Any help would be appreciated.

Thanks

Which client version? Which OS? Is the libvdpau package installed?

I am running the latest Xibo, v-1.4.1 on Ubuntu 10.04.

How do I confirm if libvdpau is installed? I do not have much experience with Ubuntu.

Thanks

apt-get install libvdpau

From a terminal

Maybe I'm missing something but using sudo apt-get install libvdpau from the terminal results in this message:

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package libvdpau

Is the package called something else? Does the fact that I have an ATI card have anything to do with this?

Thanks, that package was valid, but the system says its already the newest version.

Output:

Reading package lists... Done
Building dependency tree
Reading state information... Done
libvdpau1 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I ran apt-get update and then ran the install command again and it still says that the newest version is installed.

Any ideas?

I've just seen the same error on an Intel graphics based machine but there it's not causing any problem, so I don't think that's the cause of your Seg Fault.

All I can suggest is using known-supported hardware as it's much more likely to work in that scenario.

Your software is looking for this file : libvdpau_nvidia.so

This file is a library. Libraries are usually put in /usr/lib/. If you look in that directory, you may find files like /usr/lib/libvdpau_nvidia.so.1.0.0 or /usr/lib/libvdpau_nvidia.so.1. What you want to do is to create a symbolic link to that file and give it the name of libvdpau_nvidia.so, for example, in my configuration :

ln -s /usr/lib/libvdpau.so.1 /usr/lib/libvdpau_nvidia.so

You may also find this file in a subdirectory called vdpau, look for it.

I hope this helps.

Can you help with this problem?
