rtsp timeout av_read_frame
30 novembre 2012, par user1175197I am using ffmpeg to play an RTSP stream. I have a loop like
while (av_read_frame(formatContext, packet)>=0)
{
doWork();
}I can watch the stream as long as there is something moving in front of the camera. But whenever the view is stable the above function returns EOF as I checked with av_strerror. Any ideas why and how to fix it ?
thanks
