Question

this is part of a project I am working on. I have two desktop java application , one runs on the server (which has real IP), and the other is the client. I just want to stream a live video from a webcam connected to the server application , and play it on the client application. I want to do this streaming from more than one camera.

I have been looking searching for days between Xuggler, JMF, Red5, VLCj. I just can’t figure from where I should start as I am new to dealing with media in programming.

Any ideas from where I should start with this ?

Thanks in advance

I suggest you to go with VLCJ, because in addition to live video streaming, you get all features of VLC media player available to your application. Also, it is available for Linux,Windows, and Mac. If you can live stream your webcam with VLC, then you can do the same with VLCJ.

Refer VLCJ wiki page for details on how to use it. They provided many examples in the wiki. Here is an example of Http Streaming using VLCJ. Copied from VLCJ examples.
