问题
I tried one of sample DirectShow based virtual camera https://github.com/roman380/tmhare.mvps.org-vcam I am able to compile and build and its working fine in Google Meet.
But this virtual camera is not working properly in Zoom and other Desktop apps. Its visible as video device but not showing any content like I am able to see random data in Google Meet.
Zoom is using DirectShow as well as Media Foundation So Virtual camera is visible in Zoom. In zoom on selecting Virtual camera I am seeing black screen only.
What can be the reason and how can I fix this problem? Do I need to develop proper driver to make this working?
