[SOLVED] Fresh installation of Slackware 14 RC2: libvdpau_nvidia.so not built...

andrew.46 · 08-21-2012, 03:04 AM

I have made a fresh install of Slackware 14 RC2 and also installed libvdpau (0.4.1), nvidia-kernel (302.17) and nvidia-driver (302.17) from SBo, in that sequence. All goes well but MPlayer cannot use -vo vdpau with the message that:

Code:

Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: 
No such file or directory

and in fact libvdpau_nvidia.so is not built and is not present on my system. Has anybody else had this problem? Could be as usual that I am doing something wrong

.

How do you mean "not built"? If it created a package, it should have built something. Are you sure you remembered to install the generated libvdpau package?

Try it again, and post the configure and compile output (on via email). As soon as I restore my -current VMs, I'll check it out.

Edit: Almost forgot - does your mplayer have vdpau support? ffmpeg? IIRC the stosck install doesn't. I run newer mplayer/ffmpeg etc that has vdpau added.

I mean the file libvdpau_nvidia.so was not built and installed. As I was in a rush I will admit that uninstalled the SBo nvidia-* and installed the 304.37 drivers using the NVidia installer. Built fine with libvdpau and I now have acceleration with MPlayer again. The errant file was installed by NVidia's installer:

Code:

root@skamandros/home/andrew# find /usr -iname  libvdpau_nvidia.so
/usr/lib64/libvdpau_nvidia.so

I compile my own from svn and git respectively. I will be interested to see if anybody can replicate my problem, but I am flying happy atm using the NVidia installer...

Code:

bash-4.1$ locate libvdpau_nvidia.so
/usr/lib/vdpau/libvdpau_nvidia.so.304.37
/usr/lib/vdpau/libvdpau_nvidia.so.1
/usr/lib/vdpau/libvdpau_nvidia.so
bash-4.1$ grep libvdpau_nvidia.so /var/log/{packages,scripts}/*
/var/log/packages/nvidia-driver-304.37-x86-1_SBo:usr/lib/vdpau/libvdpau_nvidia.so.304.37
/var/log/scripts/nvidia-driver-304.37-x86-1_SBo:( cd usr/lib/vdpau ; rm -rf libvdpau_nvidia.so.1 )
/var/log/scripts/nvidia-driver-304.37-x86-1_SBo:( cd usr/lib/vdpau ; ln -sf libvdpau_nvidia.so.304.37 libvdpau_nvidia.so.1 )
/var/log/scripts/nvidia-driver-304.37-x86-1_SBo:( cd usr/lib/vdpau ; rm -rf libvdpau_nvidia.so )
/var/log/scripts/nvidia-driver-304.37-x86-1_SBo:( cd usr/lib/vdpau ; ln -sf libvdpau_nvidia.so.304.37 libvdpau_nvidia.so )
bash-4.1$

This is on Slackware 13.37.

True too after the NVidia installer had done its work:

Code:

root@skamandros/home/andrew# find /usr -iname libvdpau_nvidia.so*
/usr/lib64/libvdpau_nvidia.so
/usr/lib64/vdpau/libvdpau_nvidia.so.304.37
/usr/lib64/vdpau/libvdpau_nvidia.so.1

But this was not present when I used the SBo script. I am not that keen to dig deeper if it was perhaps a simple glitch on my own computer that nobody else can reproduce, in which my apologies to kingbeowulf for the noise. Mind you it was a fresh rc2 installation and I have installed SBo NVidia drivers often before...

So now I add the NVidia installer to the VirtualBox installer that I also guiltily use

.

I have done that too in the past and do not feel guilty at all

Nevertheless I will use SBo slackbuild in Slakware 14 RC2, as that could help kingbeowulf to find out what's wrong if I can reproduce the issue.

I have posted the entire slackbuild process for the nvidia-driver here:

Perhaps this will be helpful...

Do you need this if you use the SlackBuilds for the NVidia driver and kernel?

http://slackbuilds.org/repository/13...ries/libvdpau/

I use the NVIDIA-Linux-*.run, but I use plenty of other SlackBuilds and my conscience is clear.

andrew.46 · 08-21-2012, 06:45 AM

Yes, and this (libvdpau 0.4.1) is installed on my system....

Code:

andrew@skamandros~$ ls /var/log/packages | grep libvdpau
libvdpau-0.4.1-x86_64-1_SBo

Didier Spaier · 08-21-2012, 06:47 AM

Well, I forgot that I already installed it in 14 RC2. No problem there, the shared library and the links are in /urr/lib/libvdpau as well.

I first installed iibvdpau-04.1 then nvidia-{kernel, drivers}-304.37

andrew.46 · 08-21-2012, 06:56 AM

Is it a 64bit problem? I note mine is a 64bit install while yours is 32... no idea why this would make a difference

Taking a quick look at the SlackBuild, libvdpau is omitted from being installed. The directories are created, but the library is not installed.

Somewhere in the SlackBuild, something like this needs to be added

Code:

install -D -m755 libvdpau_nvidia.so.$VERSION $PKG/usr/lib$LIBDIRSUFFIX/vdpau/libvdpau_nvidia.so.$VERSION

And of course, you need to create the shared link towards the bottom of the SlackBuild like the others.

IIRC, there was a discussion about libvdpau on the SBo mailing list, about it being included in one version, but not the other, or something with multilib .... not sure. For us (meaning myself, and those that work/use the PCs here), it's far too simple to just download the binary installer from Nvidia, and execute. The installer also has a built in update function which will fetch the newest version, will create the needed blacklist file for nouveau, and has a clean uninstall function.

extra/xf86-video-nouveau-blacklist-noarch-1 is not needed?

Edit: I see it will blacklist nouveau if detected:

Nvidia devs recommend packagers to separate libvdpau from the proprietary nvidia kernel and driver installers as vdpau will we removed "real soon now"

The nvidia-*.run installer installs the one that is precompiled. Hence the separate package. This is also the reason the nvdia-driver.slackbuild requires several other source packages (e.g. nvidia-settings) instead of using the precompiled versions in the installer.

Six of one, half dozen of the other, as they say.

I tested everything on current-beta, but not yet on RC1 or RC2: My -current VM doesn't have a Nvidia GPU! So, if you run the scripts and files end up missing or misplaced, let me know. The newer nvidia-*.run versions have moved a bunch files around.

Thanks for posting a fix to SBo beowulf

. I will admit that I am staying with the nVidia installer for the moment but thanks again for looking at this issue.
