Crash with OBS virtual camera

[mkoch44]

Start "Virtual Camera" in OBS. Open this camera as video source in GraphStudioNext. Show the properties of the output. Crash.

I have found that the OBS DirectShow filter is pretty deffective. The crash could be a problem of OBS itself and not GraphStudioNext. Try to get callstack.

This issue should be closed here, but the same issue should be created for OBS camera developpers. It is solely problem of OBS camera itself:
