RTSP Feed instead of using Webcam?

[Ganesh-Baron-Aloir]

Hello Torin,

Awesome work on this repo. I'm trying to figure out how it would be possible to modify the code to enable RTSP feed input instead of a webcam.

The reason, I'm trying to figure this out is because, I realize that when needing multiple types of data, faces, landmarks, and so on, we get better results by running multiple MediaPipe bases for marginal performance costs. I'm using NDI webcams instead of Spout right now, because it allows me to share the same feed over 4 MediaPipe bases on the same machine, but I'm limited by the 4 NDI Cam sources.

I believe that with a multicast RTSP it would be possible to use the same source across multiple instances of MediaPipe bases.
