Bullseye // KMS // VLC

Hi Guys,

is it currently possible to play a stream with Bullseye or should we better keep Buster? Following some logs:

On the whole buster is going to be easier for a while. I have a V4L2 / DRM implementation for VLC4 but it isn't ready for prime time yet, and in all honesty, due to the limitations imposed by linux vs mmal the buster version is likely to work "better" for many purposes for at least some time.

Is there an ETA, when VLC on bullseye is on par with VLC on buster? Thanks

I join the request I use Raspi in Interactive Art projects, and, for me, it is useless without accelerated video in the cli. So I'm stuck with Buster.

I got around this bullseye-induced issue for my project by setting the GL driver to "Legacy" in raspi-config.

My VLC cli-only onvif viewer project required the following feature that doesn't seem to have a KMS alternative: --mmal-vout-window
