General Usage

This document will describe how to execute some of the most important types of commands used with the device service.

Execute GetStreamURI Command through EdgeX


Make sure to replace Camera001 in all the commands below, with the proper deviceName.

  1. Get the profile token by executing the GetProfiles command:

    curl -s | jq -r '"profileToken: " + '.event.readings[].objectValue.Profiles[].Token''
    Example Output:
    profileToken: profile_1
    profileToken: profile_2

  2. To get the RTSP URI from the ONVIF device, execute the GetStreamURI command, using a profileToken found in step 1:
    In this example, profile_1 is the profileToken:

    curl -s "$(base64 -w 0 <<< '{
        "StreamSetup" : {
            "Stream" : "RTP-Unicast",
            "Transport" : {
            "Protocol" : "RTSP"
        "ProfileToken": "profile_1"
    }')" | jq -r '"streamURI: " + '.event.readings[].objectValue.MediaUri.Uri''
    Example Output:
    streamURI: rtsp://

  3. Stream the RTSP stream. ffplay can be used to stream. The command follows this format:

    ffplay -rtsp_transport tcp "rtsp://<user>:<password>@<IP address>:<port>/<streamname>"
    Using the streamURI returned from the previous step, run ffplay:
    ffplay -rtsp_transport tcp "rtsp://admin:Password123@"

    While the streamURI returned did not contain the username and password, those credentials are required in order to correctly authenticate the request and play the stream. Therefore, it is included in both the VLC and ffplay streaming examples.

    If the password uses special characters, you must use percent-encoding.

  4. To shut down ffplay, use the ctrl-c command.
