I can stream to youtube with ffmpeg fine but I wanted to test out streaming an IP cam to facebook live with their API. I couldn't get it to work with ffmpeg, probably user error, but that only lets you stream one camera anyways. I downloaded OBS (open broadcaster software) and it lets me bring in multiple cam streams, resize them so you can do picture in picture, all kinda neat stuff but the cam streams are kinda glitchy. Anyone else know of any software that works well for something like this? xsplit might work but I run linux so I'd have to run a virtual machine just to stream the cams.
