Ok so first of all I know that EasyCap isn't the best Capture Card out there but I got it as a gift so I want to be able to use it. So using the program by itself works fine I can record and it comes out fine, but if I try to capture the window with OBS it doesn't show up on the stream... the weird thing is that OBS can see it but if you look at the stream it has just a dark purple screen. I've tried to mess with all the different setting for it as well as tried different programs, but nothing works.

If anyone could help me that'd be great if not I'll probably just get one of the "better" CCs

For obs put it as video capture device and then it should appear as OEM device then you go ahead and click that. In configure I use PAL_M then i just click use default on the video settings. Also then in open crossbar you change the input and you can link stream audio if you want oh btw you will have to open your crossbar and change to input everytime you stream.
