Member Function Documentation

bool RTCPCompoundHandler::checkCompoundRTCPHeader ( size_t len )

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.
