Overview

Encoded Media appliance streams can be delivered via RTSP unicast, UDP multicast or directed UDP unicast streams. You can test these streams in third party products such as the desktop and mobile app versions of VLC media player.

 

Testing streams in VLC media player

Windows and macOS

  1. In the VLC media player desktop application, open the Media menu and choose Network Stream
  2. For a unicast stream, paste the RTSP link directly e.g.
rtsp://192.168.5.123/live/AUX1
  1. For a multicast stream, paste the multicast IP and port number e.g.
udp://@226.176.238.142:10000

 

iPhone and Android

  1. In the VLC media player app, tap the VLC cone in the top corner and choose Network Stream
  2. For a unicast stream, provide the RTSP link directly e.g.
rtsp://192.168.5.123/live/AUX1

 

Stream nuts and bolts

MPEG transport stream (MPEG-TS) is raw UDP. Packet size is 1,316 bytes (1,358 bytes including UDP and IP headers). TTL is settable, with the system default being either 15 (platform 3 and later) or 5 (platform 2 and earlier).
