Package: vlc Version: 3.0.20-0+deb12u1 When playing an AV1 encoded video from webm file, video display is blank and only audio is working. It seems to me that vlc tries hw acceleration via VDPAU although my card does not support AV1 hardware decoding. VLC should fall back to software decoding in this case. (It works properly if I disable hardware acceleration entirely in vlc)
