I've found that IP Webcam functions fairly well as a standards-based H.264/RTSP video stream to feed to anything that can take a rtsp feed. Such as for a hacked up DIY home security camera system.

Interesting info, thank you.

Searching around for RTSP, I found that it's possible to stream to WebRTC.

I've used DroidCam over USB and for me it was slower than over wifi.

What do you mean by adb port forwarding?
