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the vdpau-driver-all dependency updated): the latest upstream was in 2016, and the package description is probably out-of-date.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. -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)
