VLC with VDPAU does not display the video : hardware accelerator failed to decode picture.
The audio works fine.
The vdpau drivers are installed :
$ dpkg -l | grep vdpau
ii libvdpau1:amd64 1.3-1ubuntu2 amd64 Video Decode and Presentation API for Unix (libraries)
ii mesa-vdpau-drivers:amd64 21.0.3-0ubuntu0.3~20.04.3 amd64 Mesa VDPAU video acceleration drivers
ii vdpau-driver-all:amd64 1.3-1ubuntu2 amd64 Video Decode and Presentation API for Unix (driver metapackage)
ii vdpauinfo 1.0-3build1 amd64 Video Decode and Presentation API for Unix (vdpauinfo utility)
Here is the vlc output :
