    - Multimedia Streaming Server: Overview
      The Multimedia Streaming Server, mm-stream, is a network media server that can stream video and audio content over IP networks. Remote clients can access the media streams using RTSP or RTP.
    - Configuring the mm-stream server
      You can create mm-stream instances by providing raw JSON data or making the server read the configuration file named on the command line that started the process.
