Functions

@spec parse(binary(), opts :: Keyword.t()) :: {:ok, t()} | {:error, atom()}

Parses SDP Attribute line.

line is a string in form of a=attribute or a=attribute:value. opts is a keyword list that can contain some information for parsers.

Unknown attributes keys are returned as strings, known ones as atoms. For known attributes please refer to t().
