Viewing Video Streams

To view streaming video from the Harrier IP Camera Interface Board you will need a media player such as

VLC media player or GStreamer. Streams can also be viewed in the ONVIF Device Manager. There are

three stream profiles available:

•

quality_h264

•

balanced_h264

•

bandwidth_h264

The profile to be displayed on the player is specified in the stream connection:

rtsp://<IP address>:8554/<profile>

Using VLC Media Player

•

Install and open

•

From the Media menu, select Open Network Stream

•

In the Open Media dialog, enter rtsp://<IP address>:8554/quality_h264

•

Click the Play button

Using GStreamer

•

Install

GStreamer

(https://gstreamer.freedesktop.org/download/)

•

Run the following command:

gst-launch-1.0 rtspsrc location=rtsp://<IP Address>:8554/quality_h264 latency=0

! decodebin ! autovideoconvert ! autovideosink sync=false

Note: to make GStreamer work on Windows, you may need to update the 'PATH' environment variable and

set the GStreamer environment variable; for example:

set GSTREAMER_1_0_ROOT_X86_64=c:\gstreamer\1.0\x86_64\

set path=%path%;%GSTREAMER_1_0_ROOT_X86_64%\bin;

Controlling the Camera

The ONVIF standard defines and supports control for various camera settings and client applications should

use the ONVIF Imaging service to control these camera settings (please consult the ONVIF documentation

for more information, see section 'Getting Started with the ONVIF API' below).

However, block cameras typically have many other settings/features that can be controlled using VISCA

commands sent over the camera serial interface (see figure 3). With the Harrier IP Camera Interface Board,

applications can use the ONVIF DeviceIO service to send and receive VISCA commands to the camera.

Note: applications should not use VISCA commands to change settings that are controlled by the ONVIF

Imaging service (e.g. camera resolution and frame rate).
