![]() Update the |cumulative_lost_| counter per received packet. The rules follow from RFC 3550 and are fairly simple: Decrement the counter by one for every received packet. For every in-order packet, i.e., increasing |received_seq_max_|, add that change to |cumulative_lost_|. Net change is zero as long as packets are received in proper sequence. This way, GetStats() always returns an up-to-date value, independent of the timing of RTCP report blocks. For RTCP reports, keep a workaround to never report negative cumulative loss.
