This sounds a bit wrong to me. Should it be OnReceivedRtcpReportBlocks()?
Technically I don't think an SR includes a receiver report.

The current implementation seems to indicate the SR and RR *can* both include

Ack, I'd prefer OnReceivedReportBlocks, especially since report blocks are what
you really pass in.
