Hey.

This version breaks e.g. video playback with mpv (also vlc):
$ mpv test.mp4

(+) Audio --aid=1 (aac 2ch 44100Hz)
Segmentation fault

Downgrading to 22.0.2+ds1-1 fixes the issue.

Cheers,

I thought it was `forwarded`, but changed after reading the example in
*How to report a bug in Debian using reportbug* [2], which turned out to
be wrong.

Kind regards,

I do have:
hwdec=auto

in mpv.conf, which I think would use vaapi here.

However, I have nothing specifically set for VLC.

Thanks,
