How to collect streams from cameras and show video?

Question

Video broadcast

There are 2 cameras and a weak upload channel, I want to put a local server on the object, merge video from the cameras in MJPEG format to it and then, upon request, give it to clients in real time for viewing. What does it have to do with making a video buffer for 15 seconds before showing the client.
From which side to go, tell me where to dig.

Answer 1

have you tried motion ?

Answer 2

If the cameras are IP, then they have an API, smoke in this direction (there is the possibility of receiving a video stream, just pictures, etc.). And for the buffer - create a queue. You record frames into it until the required amount is reached, after which you start sending more ...

Answer 3

I liked avreg.net/ the
server loads much less than the same zoneminder. Depending on the tasks, you can also look at motion as a wrapper

Answer 4

a bit off topic, but try ivideon
or via vlc and mencoder
