[Libav-user] TCP + rtsp time delay.

Connecting RTSP Server using UDP, have seen huge packet loss, and resulted
to flickering images, hence configured to use TCP like:
AVDictionary *stream_opts = 0;
av_dict_set(&stream_opts, "rtsp_transport", "tcp", 0);
The issue what i see is at the initial period, the time delay between RTSP
server and av_read_frame() is around 1 sec, and which grows gradually to 5
sec after some time, then it gets somehow reset to again 1 sec. Server is
sending for about max 25 fps, min is 18 fps.

I am not sure where i can hook around ?. Please advise?.
P.S: I am not using any PTS calculation, but simply dumping completed
frames into UI.
