# MultiplexChannel

Using MultiplexChannel, you can combine multiple internal streams into one ABR stream, or duplicate the stream and send it to another application.

MultiplexChannel can be controlled by API or file. See below for more information about MultiplexChannel.

The body of the API all has the same structure as the mux file.
