Hi. I need to capture a MPEG4 stream from an IP camera. I want to use ffmpeg to handle all the streaming thing. So far the rtsp negotiating goes well but I run into a problem: the camera demands RTCP receiver report messages both to start streaming and keep the conection alive. I understand (from guides and examples found through google) that av_open_input_file() and av_read_frame is the way to go. av_open_input_file() does the RTSP negotiating just fine but it doesn't send the rtcp rr report. I've looked over the ffmpeg doc and there is a function (rtp_check_and_send_back_rr) it seems to solve my problem but I'm not sure how to use it. I thought it would be called internally by some other high level functions but maybe I have to call it myself. I'm using the Ubuntu 9.10 ffmpeg built (if it matters). Thanks in advance.
