    - 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.
      - Configuration file examples
        This section provides sample configuration files that illustrate how plugins can be configured to read, encode, and output audio or video streams with specific settings and formats, for both RTP and RTSP means of access.
      - Configuration syntax
        The mm-stream configuration lists and configures the plugins used by clients for accessing the server, and by the server for reading input, processing media content, and delivering output.

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.

The configuration defines:

the URLs of the media sources
how to read the inputs (e.g., the sampling and frame rates to use)
the audio and video codecs to use when encapsulating content into MPEG2 Transport Streams
the output plugins for delivering content to its destination
the IP addresses and ports of the mm-stream server and the output stream destinations

On the command line, you use the -c option followed by an absolute path to the configuration file. In an mm_stream_set_configuration() API call, you must specify the configuration in JSON format. The syntax details for either method are the same and are shown in the subsequent examples.

At startup, mm-stream reads its configuration file and creates one or more instances, based on the file's content.
