Hello Alexander,

Thanks for the suggestion.

But libvdpau itself already has code to look for the available drivers
and pick one, and the env var is left so that the user can manually
override if he/she chooses to.

On which setup are you encountering this issue? I would perhaps be
better trying to fix it in the library itself, if possible, before
adding a new script. Could you please share more details about your
system, and the result of reportbug --template libvdpau1 ?

Thank you!

Kind regards,
