This document records one of the simplest video site systems. Prior to doing some Java EE based on the SSH (Strut2 + Spring + Hibernate) site system, but has not done a video site system, so it is intended to do a "streamlined" video site system to facilitate future testing and learning to use. This video site supports live streaming (via rtmp) and on-demand (implemented via HTTP). In order to remain streamlined, this video site system only makes the

After installing Darwin streaming Server, you can use VLC to play streaming media files through the RTSP protocol. But now I have a need to send a DSS (assumed to be a machine) on the media file to another DSS (assuming B machine) on the client VLC by accessing the B machine to play the media files of a machine, that is, using B machine as a forwarding server. I found a lot of articles on the internet about configuring DSS, all of which are about how to install and configure playlists, not how t
