What we are going to run this time testOnDemandRTSPServeris in this directory.

Four, live555 running

The purpose of this operation is to run on a virtual machine testOnDemandRTSPServer, and send the h264 file to VLC on the windows side through rtsp for playback.

1. testOnDemandRTSPServerThe file has been compiled in the previous step, but the h264 file is not yet available. You can download it from the Internet yourself, or you can download it from the live555 official website http://www.live555.com/liveMedia/public/264/test.264 .
