Is it able to solve virtual cam unavailable problem? Formal 0.3 doesn't work at all at any platform.

I know it works on Zoom, but streams very slow.

Sorry for more questions, have you test it on Intel or Apple Silicon(M1) laptop?

I used Intel for testing, I know virtual cams give a bit of issues on M1. I tried using streamlabs official software on M1, but didnt seem to work on major streaming platforms.

Thanks a lot! May I know how to test this fix? If rebuild it and put the plugin into libobs is necessary, could you please tell me the whole process?
