@var{port} specifies the RTP port to use.
@var{options} contains a list of &-separated options of the form
@var{key}=@var{val}.
@var{key}=@var{val}. Standard percent-encoding (and using the plus sign for
space) can be used to escape keys and values.
The following options are supported:
Options can also can be specified via command line options (or in code via
@code{AVOption}s).
The list of supported options follows.
