Bug#1021601: vlc: VAAPI hardware acceleration no more available

[bob_smith_1337]

This is also the case for me with VLC 3.0.18-2 (current debian bookworm version)

Is there any workaround ?

Thanks a lot

With a fresh config, my VLC in bookworm would play the file with a bit
less than 1 frame per second... console output:

The system here is a Intel Pentium Silver J5005 with built-in "UHD
Graphics 605" (Gemini Lake).

My workarounds: one of

* explicitly configure VLC for XVideo output - no GPU acceleration but
at least an acceptable picture; (this would have been what I expected
VLC to do out-of-the-box)

* use "mpv --hwdec=vaapi"

* use the Flatpak VLC version ("org.videolan.VLC") - though that pulls
in more than 1 GB of platform data, if you didn't use flatpak before.

Best regards,
Viktor.
