Hi all, I am trying to syncronize the reproduction of a live RTSP (not seekable) stream in different two different process. At the moment I am using the PTS given from av_read_frame (from libavformat) and I noticed that each RTSP session starts counting its timestamp from zero, independently from the time the session is initiated.
At the moment, I am having pretty successful results initalizing my inner timestamp to the system clock when the first frame arrives, then from them I am just adding the offset given by the PTS (obviously taking into accout timeBase units). I pretty sure this it no the way to do it and that ffmpeg might provide some better options. So the question is, should I (or can I) set the AVStream->start_time value to some sort of system clock in order to be able to compare the current demuxed timestamp witht he one in another process? Does FFMPEG have any kind program clock reference? Thanks in advance for any advice, David _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
