Why does VLC try to find the Nvidia Vdpau backend ?

[shirish]

Hi there,
I have an intel integrated sound and video chipset . pacmd telling/sharing what audio sink is available and used.

Code: Select all

[$] pacmd list-sinks|egrep -i 'index:|name:' * index: 0 name: <alsa_output.pci-0000_00_1b.0.analog-stereo>

lspci tells this :-

Code: Select all

[$] lspci | grep Audio 00:1b.0 Audio device: Intel Corporation NM10/ICH7 Family High Definition Audio Controller (rev 01)

and this as my Video :-

Code: Select all

─[$] lspci | grep VGA [17:51:35] 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10)

Anyways, when I run a media file in vlc I often get readings like these :-

Code: Select all

[00007f9550001268] xcb vout display debug: using screen 0x7b Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory

These are the flags with which vlc was built in Debian testing by the Debian maintainers :-

Just to add these are the capabilities the CPU has on this system :-

Code: Select all

[0000000000a27148] core libvlc debug: CPU has capabilities MMX MMXEXT SSE SSE2 SSE3 SSSE3 FPU

Is there a way to disable or blacklist so that it doesn't try to find that libvdpau_nvidia.so library. While I do have some more issues which I'll share in due course, this will make it one less thing to worry about, if it can be done.

That error comes from libvdpau, not VLC. Maybe your X11 display driver does not implement the DRI2 extension?
