Detailed Description

       low level structs and RTCP packet parsing and building methods.

       Intended to be used, through inheritance, in RTCP management classes, such as
       QueueRTCPManager.

Member Function Documentation

   bool RTCPCompoundHandler::checkCompoundRTCPHeader (size_tlen) [protected]
       Perform RTCP compound packet header validity check as specified in draft-ietv-avt-rtp-new.
       This method follows appendix A.2. Correct version, payload type, padding bit and length of
       every RTCP packet in the compound are verified.

       Parameters:
           len length of the RTCP compound packet in the reception buffer

       Returns:
           whether the header is valid.
