Title:
[snap] VA-API does not work with nvidia proprietary drivers
Status in chromium-browser package in Ubuntu:
Triaged
Bug description:
After installing the candidate/vaapi channel, I still do not get
hardware acceleration for video decoding from my NVIDIA gpu, see:
```
$ LIBVA_MESSAGING_LEVEL=2 snap run chromium
Gtk-Message: 09:07:37.215: Failed to load module "canberra-gtk-module"
Gtk-Message: 09:07:37.216: Failed to load module "canberra-gtk-module"
libva info: VA-API version 1.7.0

[141337:141337:0710/090737.297551:ERROR:vaapi_wrapper.cc(480)] vaInitialize
failed: unknown libva error
```
For me, I am on Focal, so I had to manually install the vdpau-va-
driver from cosmic from https://launchpad.net/ubuntu/+source/vdpau-
video/0.7.4-7, (presumably on i.e. 18.04 I could just have installed
it with apt install), which provides the various files in
/var/lib/snapd/gl/vdpau, and then I also had to add that package along
with libvdpau1 into the chromium snap, at which point it loads the
libraries but I then run into very relevant errors:
```

```
at which point I am stuck trying to get it to work.
FWIW, this is with ubuntu 20.04, snapd 2.45.1, nvidia drivers 440, and
X11 with gdm.
Also I had to modify the desktop-launch script with this PR:
https://github.com/snapcore/snapcraft/pull/3209 otherwise it would not
find the /var/lib/snapd/lib/gl/vdpau dir on $LD_LIBRARY_PATH
