problems with vdpau & mplayer [SOLVED]

[ufster]

i get this error when i try to play videos with gnome mplayer using vdpau as the video output.
"Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory"

my mplayer was compiled using the latest snapshot from mplayer hq website with vdpau support. i used the nvidia way to install 256.35 drivers. libvdpau1 and libvdpau-dev (for mplayer compile purposes) packages are installed but since nvidia-vdpau-driver version for debian testing is at 195.36.24-4 and i presume it's version specific, i chose not to install this package.

does anybody have any suggestions as to what i should try and do to get vdapu working with gnome mplayer. my graphics card is a 8800gt with a quadro fx 3700 bios, vdpau with mplayer worked well with my previous testing installation.

note - it doesn't work with mplayer from console either, same error.

Looking inside that nvidia-vdpau-driver package, it appears it sets up the 'libvdpau_nvidia.so" symbolic link to the actual shared library provided by the Nvidia driver. Since there is no symlink, the vdpau output driver fails. I guess you installed the Nvidia driver in another manner...can you locate the actual driver file anywhere on your system? Maybe you can manually create the symlink.

locate libdvdpau returns

Code: Select all

/usr/lib/libvdpau.so -> libvdpau.so.1.0.0
/usr/lib/libvdpau.so.1 -> libvdpau.so.256.35
/usr/lib/libvdpau.so.1.0.0
/usr/lib/libvdpau.so.256.35 
/usr/lib/vdpau/libvdpau_nvidia.so.1 -> libvdpau_nvidia.so.256.35
/usr/lib/vdpau/libvdpau_nvidia.so.256.35
/usr/lib/vdpau/libvdpau_trace.so.1 -> libvdpau_trace.so.1.0.0
/usr/lib/vdpau/libvdpau_trace.so.1.0.0

/usr/lib32/vdpau/libvdpau_trace.so.256.35

i presume the actual shared library is /usr/lib/vdpau/libvdpau_nvidia.so.256.35, on the above list i marked the symlinks with a -> to their link targets
is this helpful ?

I have vdpau set in Mplayer and it works just fine.

apt-cache policy mplayer

i realize my "libvdpau_nvidia.so" is for some reason placed in /usr/lib32 and not in /usr/lib ... do you have a suggestion as to why that might have happened or how i should go about tackling my vdpau issues based on that bit of information ?

[milomak]

i found that my mplayer (sid) had issues some time back. I haven't tried to sort the issue out. There may be a conflict between packages. Maybe list

dpkg -l | grep nvidia
dpkg -l | grep vdpau

[ufster]

nothing for the nvidia... since i installed the drivers the "nvidia way" using the installer.

for vdpau
libvdpau-dev 0.4-5 Video Decode and Presentation API for Unix (development
libvdpau1 0.4-5 Video Decode and Presentation API for Unix (libraries)

[stevepusser]

There's another libvdpau1 library available in Squeeze and Sid (backportable to Lenny with a bit of change to the build-depends), but I can't say if it's compatible with the way the nvidia driver was installed.

[ufster]

cd /usr/lib
sudo ln -s vdpau/libvdpau_nvidia.so.256.35 libvdpau_nvidia.so

solved my problem. simple solution that i overlooked for some reason...
now how do i prevent this post from wasting anybody else's time ?


edit: fixed the title, thanks for the help.

Just a heads up, you should really disable compositing in your xorg.conf ( or create a sparse one that just disables compositing ) if you use the vdpau output driver a lot. It will stop the flickery tearing on HD content for one thing and it will use less CPU for the other.

Has anyone else had trouble replaying some file extensions a second time in SMPlayer with the newest mplayers? Seems they switched to a new all-in one demuxer that causes this, so far I've fixed these extensions by editing ~/.mplayer/config and adding:


[extension.mkv]
demuxer=mkv

[extension.mov]
demuxer=mov

[extension.mp4]
demuxer=mov

[extension.ogv]
demuxer=ogg

to use the older demuxers.
