I'm looking to stream a live lecture into an overflow lecture theater. I'm planning to stream HD content along with audio from a powerful server with nVidia GeForce GPUs connected to the client via a fiber connection (so hardware/network limitations are no issue) to the overflow theater with very low latency. Because the theaters are within earshot of each other, I need to try to minimalize the latency to as much that there isn't a noticeable delay between the source and destination.
I've tried VLC with RTSP and H.264 but I can't get the latency down from around 1.5 seconds which is incredibly noticeable.
Whats the best way to achieve super-low latency transmission of Audio/Video? I realize this is a broad topic but I thought I'd give it a go here, see if someone has come across a solution to this before :)
