Dear Simon,

I seems find some problem with my program, i use the h264 profile with rtp settings as below

    media_profile = rtp_profile_new("AV profile H264 Video");
    rtp_session_set_profile(session, media_profile);

and the timestamp i add 3000(90HZ/30fps) per frame, but the 6sec latency will occur after my program run about few minutes,

when i modify the timestamp to increase 2500 per frame, the latency is less then 1sec, but i don't know why, my camera is 30 fps,

it seems not a correct solution, if anyone know how to resolve it, i appreciate any help.
Best Regards,

Dear Simon,

My program have low latency requirement, and i set the rtp_session_set_jitter_compensation() less then 50

and enable rtp_session_enable_adaptive_jitter(), when my program start, the latency is less then 1 second,

but after few minutes, the latency will increase to 6 second, to achieve this, beside the

rtp_session_set_jitter_compensation() and rtp_session_enable_adaptive_jitter(), which parameters i should fine tune in oRTP
