Hi, I'm using ffmpeg to retrieve the video and data from camera. This camera sends video through rtsp and data through onvif.
I use "avformat_open_input" -> "avformat_find_stream_info" -> and get 2 streams from camera, and then I just use "av_read_frame" to do what I want to do to these 2 streams. Everything works as I expect. However, I would also like to retrieve the RTCP packet in order to get the ntp timestamp. I have no idea how to do that. Could you share some light? Thanks, Jeff
