set flag on packet for retransmition
I have implemented the libx264 codec for video call using pjsip and Im
wondering if there is any way to make sure a specific packet has arrived.
Im not talking about frames but I would like to send SEI/SPS/PPS only one
time and make sure they arrived on the other side.
At this moment I managed to send the packets but in a real world
application I cant know if they will reach the other end.
I could use something to make that signaling by myself but I would lose
conpatibility.
My real question is if I can set some flag on the rtp packet or maybe using
pjmedia itself to mark the header packets and get a response from the other
end when its all good. And of course using something RFC like.
I hope I managed to explain myself and thank you all in advance.
There isn't a mechanism to do that via RTP that I'm aware of. If the
receiver needs a key frame it requests one by sending a "picture fast
update" message via SIP INFO. PJSIP implements this mechanism. - Bill

Spoke too soon. RFC 5104 specifies a way to send a "full intra request"
via RTCP. This is a different way to do it than the "picture fast
update" sent via SIP INFO, described in RFC 5168. I don't believe PJSIP
implements 5104 unless it's a recent addition. - Bill
