Thank you for adding, I have a few comments. Sorry for the version.h failure mess, please rebase on current master.

uint8_t payload_type = header->payloadType();

if (payload_type == 206 && header->reportCount() == 15) {
auto remb = reinterpret_cast<RtcpRemb *>(message->data() + offset);

You should check the size again before casting to RtcpRemb for the sake of completeness. You could also add a method to check that the identifier is indeed "REMB".


if (payload_type == 206 && header->reportCount() == 15) {
auto remb = reinterpret_cast<RtcpRemb *>(message->data() + offset);
mOnRemb(remb->getNumSSRC(), remb->getBitrate());

Why do you pass the number of SSRCs (instead of the SSRCs themselves) in the REMB feedback message? It seems useless for the user. I think you should remove it from the callback signature. If I understand correctly, it is not necessary to pass SSRCs as the bitrate is the total bitrate for the RTP session anyway. The SSRCs should be used for dispatching across tracks in PeerConnection::dispatchMedia(), if necessary.

off topic.
i don't understand one nuance.

while (in_bitrate > pow(2, 18) - 1) {

compiler will be optimize this code ?
while (in_bitrate > pow(2, 18) - 1) {

maybe change to
while (in_bitrate > 0x3FFFF) { ?

Indeed, it should be changed. Could you do it please?

It looks good, thanks! Could you please rebase your branch on current master to remove bogus commits like "Bumped version to 0.21.1" ?

I meant not merging master but actually rebase and then force push to clean up the branch history.
