I’m building a strictly confined, non-classic snap which needs vdpau support for video playback. I’m building against the core18 base so I get newer toolchain and libraries, thus simplifying my yaml and reducing build time.
I have a wrapper script which detects the GPU and sets the various VDPAU environment variables before launching the application. However, on launch it fails to find the VDPAU drivers, which look like they have moved between Ubuntu 16.04 and Ubuntu 18.04.
libva info: VA-API version 1.1.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so
libva info: va_openDriver() returns -1
Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory
We briefly looked at the code in the snapd repo which does the magic/voodoo and it looks a bit hard-wired and fragile (being kind).
I recall a conversation on irc some months back where @zyga-snapd hand-waved doom and gloom for this stuff continuing to work.
What’s the plan for supporting opengl/vdpau/vaapi on all the GPUs going forward?
