Video streaming has only three options in the app

Video streaming has only three options in the app。Use stable V4.0 General_video(voide Steam Disable、Rear-facing camera、Front-facing camera)


In the picture there are TCP, UDP and other video modes,How can I get my APP to support these modes and choose IP and port Numbers?

What OS? Seems like maybe Android? I think front/rear facing cameras are UVC devices.
