Detailed Description

Typedef Documentation

#include <formats.h>

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.)

Definition at line 65 of file formats.h.

Enumeration Type Documentation

#include <formats.h>

RTP static payload types (default bindings) defined in the AVP profile.
