Multiple simultaneous recordings support #14

When I open two terminals and call videosnap in both at roughly the same time, the second instance waits till the first is done recording and only then starts recording even when using two different webcams. So it is not possible to capture multiple webcam streams at the same time

Interesting.. this wasn't a use case I tested for. When I have time I'll look into it. Something must be locking a resource in one of the processes.

We are filming our RPG sessions in similar format as Critical Role using 3 full HD webcams. So far we've done it through Open Broadcast Software with a dedicated person switching shots between cams, but I would rather do this in post production. I wasn't able to find any software to do this. With a little hack, you can open multiple OBS instances, but they block each others webcams. It is doable but a huge pain. I also tried FFmpeg, which I was able to use, but produced a video of such a low quality, I gave up.

Thanks for the context, I'm quite busy at the moment but will update you here when I have the time to check this out.
