TBH, I don't really see why you need to know that. The only data size you
should ever need to guess when receiving RT(S)P is that of the largest
possible RTP packet.
Video frames should be fragmented. In my understanding, the packetizer or the
decoder is responsible for reassembling full frames if the codec requires it.
