Bug#1112130: libvdpau1 should not recommend vdpau-driver-all (libvdpau-va-gl1 breaks VLC)

[Vincent Lefevre]

Control: reassign -1 libvdpau1 1.5-3
Control: retitle -1 libvdpau1 should not recommend vdpau-driver-all (libvdpau-va-gl1 breaks VLC)
Control: severity -1 serious

Raising the severity because this breaks another package (vlc).

Since the goal of vdpau-driver-all is "This package depends on the
full suite of drivers for the VDPAU API.", I suppose that the issue
comes from libvdpau1, which should not recommend vdpau-driver-all
(perhaps only drivers that are known to work).

Or perhaps libvdpau-va-gl1 should just be removed from Debian
(with the vdpau-driver-all dependency updated): the latest
upstream was in 2016, and the package description is probably
out-of-date.

Even though recommended packages can be removed, broken packages
should never be installed by default.
