[FFmpeg-user] getting wall clock time from rtsp stream

We tried this via the docs but got lost heavily. We need the actual wall
clock time of video data from a camera which delivers via rtsp. I have read
around that there are things like RTCP sender reports and such on the low
level containing this info, and I have seen indication that it is somehow
parsed by ffmpeg. What is the easiest way to get to this information? Best
wpuld be command line dump of the time of the first frame, but rendering it
somewhere, or even hacking ffmpeg would be doable too.
Very thanlful for help, as we really need this to sync the video data to
sensor data form other sources.
