Ok I got this working - It's something to do with the VLC package in the Raspian repo, though I don't know enough about this stuff to determine what/why. raspian repo purge vlc install vlc - says ~200kb will be used using https://www.deb-multimedia.org buster main non-free purge vlc install vlc = sa...

It's a document camera - Ipezo VZ-R

Unfortunately I don't have any other cameras to try

Appears to be Raspian specific issue. Putting Ubuntu on the Pi everything worked as expected.

At the moment Core, Core.Interops, and Forms (WinForms app) are all on 3.0.0-develop322. I will get some logs today.

I am working on a video intensive application and have chosen to use libvlc for playback. Technically I'm interacting with libvlc through the Vlc.DotNet wrapper, but I don't think my issues are wrapper related. The app can have as many as 8 1080 videos up, and the content being played is 30fps. A us...
