videoQC Network Stream Playback

You can use videoQC to view a variety of network streams.  To attach to a network IP stream, run videoQC and select "open stream".  If you want to automatically attach to a stream from a browser link, precede any of the links below with videoqc:// and the browser will load videoQC and the stream automatically.  For instance:


 videoQC open stream

This will bring up the Open url dialog

videoqc open url

This is where you can enter the network URL.  It will also remember the last 10 URLs you have used.

  • UDP - udp://
    • Multicast or direct address plus port
  • RTP - rtp://
    • Multicast or direct address plus port
    • Also supports TR-01
  • SRT - srt://
    • Multicast or direct address plus port
    • mode=
      • listener
      • caller
      • rendezvous (not supported yet)
    • password=<password>
    • user=<user>
    • Reader Only Settings:
      • MinFramesToBuffer=#  the minimum number of frames to leave buffered (default: 2)
      • FramesToBuffer=#  the maximum allowed number of buffered frames (default: 20)
  • RTSP - rtsp://
    • The RTSP string is completely dependent on the source
  • NDI - ndi://USER-PC (Logitech QuickCam 9000)
    • The string after ndi:// will be defined by the stream source. 
    • The dialog will attempt to find local streams and populate the pulldown menu
  • SMPTE 2110/2022
  • videoQC browser links
    • Precede any of the above with videoqc:// and remove their colon.  So udp:// becomes
    • videoqc://udp//
