Mh, it looks like something weird happened with these set of updates with VLC. I get a segfault when I try to read a video file in VLC. It’s fine on mpv though.
VLC didn’t get updated with this update set, so I guess we got a crappy version of one of its dependency (libva perhaps?).

To be investigated, it’s late for me.

EDIT: Well, it looks like I am not the only one getting the exact same error.
EDIT2: It think it might be caused by NVIDIA drivers actually. libva and many packages related to hardware acceleration got updated, but we got no update for nvidia utils which provides software for hardware acceleration for NVIDIA GPUs. I would try to rebuild nvidia-utils and the NVIDIA drivers and release it in repos to see if it fixes the issue.
EDIT3: Made some progress with this issue. It looks like VLC doesn’t like the new version of libva that we got. If I downgrade libva from 2.17.0 to 2.16.0, VLC works properly again. Weird.
EDIT4: VLC works properly with libva at version 2.17.0 if I set the Output option in Preferences > Video at VDPAU output instead of Automatic (the latter being the default setting).
