## 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.*
