title: rtsp stream of an IP camera is much more delayed in VLC than in the NVR
body: <p>I have an IP camera that i can view in VLC via the link <code>rtsp://admin:admin@192.168.1.199:554/mpeg4/ch0/main/av_stream</code> but i noticed there is a significant delay to the video in vlc compared to when the camera is viewed in the NVR. The vlc has a delay of 4-6 seconds while in the nvr its barely noticeable at all  less than 1 second of delay.</p>
  <p>I need to know why that is so i can then plan out what methods/libraries to use in the program im going to make. It helps to know why so that a possible work aroung maybe explored.</p>
  <p>Is this a problem inherent to vlc or a limitation to rtsp?</p>
  <p>Is there any way i can reduce this delay?</p>
