How to use Impath Networks i5110 encoder hardware with Wowza Media Server

Instructions for integrating the Impath Networks i5110 series encoder stream with a Wowza media server solution. Refer to the Wowza Software Documentation webpage for details about the installation and operation of the Wowza media server software.


Wowza media server software can stream live H.264, AAC and MP3 content to players and devices that support the Real Time Streaming Protocol (RTSP), Real-time Transport Protocol (RTP) and MPEG2 Transport Stream protocol (MPEG-TS). This includes players and devices such as QuickTime Player, VideoLAN VLC player, set top boxes, and mobile devices. A Wowza media server can also accept incoming streams from encoding devices that use these same protocols such as the Impath Networks i5110. A Wowza media server supports RTP and MPEG-TS in and out over UDP as well as multicast. It also supports interleaved RTSP/RTP (which is where the RTP portion of the stream flows over the RTSP TCP connection) which enables RTSP/RTP to be delivered in network environment that do not allow UDP transmission.

An RTSP/RTP URL in Wowza media server software has the following form:

[wowza-address] : IP address or domain name and port of the Wowza media server (default port 1935)
[application] : Application name
[applicationinstance] : Application instance name (if omitted defaults to _definst_)
[stream-name] : Stream name with stream prefix

For example, to play the live stream located on the Wowza Media Server 2 at the address, using the application name myapplication with the stream name mylivestream the URL is:


How to publish a live stream (RTSP/RTP based encoder)

Below are the steps to set up an application named live to stream live content to the Adobe Flash player, the Microsoft Silverlight player, Apple iOS devices and RTSP/RTP based players. This technical note provides the basic steps for using RTSP/RTP based live encoders such as the Impath Networks i5110 series of encoders.
<?xml version="1.0" encoding="utf-8"?>
      <allow-from http-request-headers="*">
         <domain uri="*"/>
        <resource path="/" include-subpaths="true"/>
  1. Create application folder [install-dir]/applications/live
  2. Create configuration folder [install-dir]/conf/live and copy [install-dir]/conf/Application.xml into this new folder
  3. Edit the newly copied Application.xml file and make the following changes (some of these settings may already be present):
    1. Set the Streams/StreamType property to: live
    2. Set the HTTPStreamers property to: cupertinostreaming,smoothstreaming
    3. Set the LiveStreamPacketizers property to: cupertinostreamingpacketizer,smoothstreamingpacketizer
    4. Set the RTP/Authentication/PlayMethod to: none
    5. RTSP/RTP encoder only: Using a text editor, create the file [install-dir]/content/ and set the contents of this file to the full RTSP/RTP URL to camera. The name "myStream" is only an example, you may have several files in the content folder each containing the URL to start the stream from its unique encoder. The filenames could then be an intuitive name representing the camera.

      The i5110 URL is typically in the form, of rtsp://<device ip>/<protocol>?<optional parameter 1>&<optional parameter &>?...etc.../

      For example:
      Please refer to the i5110 user guide for details.
  4. Smooth Streaming only: Using a text editor create the file [install-dir]/conf/clientaccesspolicy.xml with the following content: 
  5. For Impath encoders add the following properties to Application.xml:
    You must also add a RTP Provider Override file to the Wowza program. This file is a Java file in the .jar format and can be downloaded from the Wowza web site at:

    You need to unzip the file into the /program files/wowza media systems/.../lib directory.

  6. Start Wowza Media Server 2.

How to play a live stream

  • [wowza-address] is the IP address or domain name of the Wowza media server.
  • The .sdp file extension on the stream name is not required. Some RTSP/RTP encoders do append this extension on to the stream name. To simplify the instructions, we have included the extension. If your encoder does not require the extension, you can remove it. Just be sure to also remove it from the stream name portion of the URL.
  • To play using Adobe Flash Player:

    Wowza Media Server 3.5
    Double-click [install-dir]/examples/LiveVideoStreaming/FlashRTMPPlayer/player.html, enter the information below, and then click the Connect button.

    Wowza Media Server 3.1.2 and earlier
    Double-click [install-dir]/examples/LiveVideoStreaming/client/live.html, enter the information below and click the Play button.
    Server: rtmp://[wowza-address]/live
    Stream: myStream.sdp
  • To play using iOS device:

    Enter the following URL into the Safari web browser:
  • To play using Microsoft Silverlight:

    Wowza Media Server 3.5
    Double-click [install-dir]/examples/LiveVideoStreaming/SilverlightPlayer/player.html, enter the information below, and then click the Connect button.

    Wowza Media Server 3.1.2 and earlier
    Double-click [install-dir]/examples/LiveVideoStreaming/clientSilverlight/Default.html, enter the information below, and then click the Play button.
  • To play using RTSP/RTP player or device:

    Enter the following URL into the RTSP/RTP player:
