ManyCam is an option, though I'm not really sure how reliable/performant.

You can try out the free version, seems ok. I was worried about it being sketchy, but it looks like it's from a team in Canada.

I'm not sure if it's true but I love the notion that Canadians are inherently better developers than the rest of the world.

I didn't mean to suggest they're better developers per se, but there's very little malware that comes out of Canada so with limited information about the trustworthiness of this application it might be inherently less sketchy than camera/mic capture software that comes out of some other countries. That said, they are in Quebec. :D

>I was worried about it being sketchy,

It's not sketchy, it's just aimed at, well, pro cammers. Or at least used to be.

Now that we're all camming, we're all in the target audience.
