Detailed Description

Typedef Documentation

PayloadType

typedef uint8 PayloadType

RTP payload type numeric identifier.

At the RTP level a payload format is identified with a 7 bit number. This number is binded to a payload format through non-RTP means (SIP, SAP, application specific rules, etc.)
