by the way, it still outputs a file. So possibly it looks somewhere else and finds it, or maybe it's falling back to another codec?

3d-illusions commented 1 year ago

doesn't this indicate the dll included with opencv needs updating to support latest gpu drivers?

3d-illusions commented 1 year ago

I'm downloading via pip opencv contrib, not building myself.

I have the same problem, does anybody have a solution for this?

Also, this ticket is marked as "dublicate" but the issue is not mentioned..
