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.
