How To Obtain and Utilize the Video Sub-Stream of a V2 Encoder on an AC-MXNET-CBOX-B/HA

How To: Obtain a V2 Encoder's video sub-stream URL to be utilized by Third Party Devices

This document describes how to obtain a URL that allows access to the Motion JPEG video sub-stream generated by a V2 encoder.
Note: This only applies to AC-MXNET-CBOX-B/HA version V4.21 or higher, and only with MXnet V2 encoders. This feature is not applicable on AC-MXNET-CBOX hardware or V1 encoders. 


How to Grab the URL of a V2 Encoder's MJPEG Sub-Stream


Step One: Log into the MENTOR interface of the CBOX-HA.

Step Two: Navigate to the AUTO-MATRIX page.

Step Three: For the desired encoder, double click on the encoder’s image preview on the left side of the page.

Step Four: On the expanded image preview window that populates, right click the preview and select “copy image address”.





Sub-stream URL Breakdown

In the above example, the URL that was copied from the V2 encoder is shown below:

The URL can be broken down to the following parameters:
http://{CBOX IP Address}:{Encoder Port Number}/?action=stream&w={Width, up to 1280}&h={height, up to 720}&bw={Bandwidth allocation(in kbps)}&as=0&dev={Encoder MAC Address}&ip={Encoder IP Address}&port=8080

Knowing these parameter values, a user can build a URL to access a V2 encoder's sub-stream without manually copying from the CBOX. 

Note: The encoder's port number and IP address could be dynamically changed if the device is power cycled at a point in time. For a more permanent URL to utilize, the Encoder Port Number parameter can be replaced with 10085, and the Encoder can be statically assigned an IP address (even if still on a link-local/APIPA IP scheme).

Using the sub-stream outside of the CBOX

Paste the copied URL (or modified URL based on the description above) wherever is desired, such as VLC media player, a supported Control System, or a new web browser tab. The preview sub-stream will populate as long as said software or device can establish a network connection to the AC-MXNET-CBOX-HA.
