red screen usually means something is not working right with the settings or device. sometimes resolution, sometimes fps sometimes that card just doesnt work (in this case we know that isn't it).Still windows 7 professional x64. The sabrent x64 driver is what was BSODing, i found the x32 driver and this is what I have now.
I don't have OBS and yawcam open together. I close one and open the other (I know 2 programs cant use one camera). Boggles me that yawcam can access the video but OBS can't.
Related note- sometimes when i select the sabrent device, a little read box appears in top left corner, sometimes it doesn't. right clicking to fill screen doesn't change anything.
