Hi, good apps. and I am using wowza streaming engine. it is working fine with my android device with build in cameras, front and back. May I know if i can use external USB camera as video source? I mean I connect my android device and connect to an external USB webcam like via a convert which connect Type-C to normal USB port. is it possible? I tried some other RTMP apps, they are able to recognize external USB camera but cannot work with wowza, because that APP do not have user-authentication.
