We used to simply synchronise on the first keyframe. This could lead to important time offets, since every audio frame is a keyframe, while we only request video keyframes every four seconds. Fix that by parsing the RTCP synchronisation data and adjusting timestamp offsets accordingly. If we have no RTCP sync, we simply assume that the first frames received are synchronised.
