Hi PuneetRaheja,

1. Is the camera and device on which you are trying to view the webstream connected to the same hotspot?

<Lakshman> Yes. camera and device (Laptop) both connected to same android mobile hot spot.

 

2. Which browser are you using for the webstream?

<Lakshman> Primarily Google chrome but also tried once using IE and Mozilla also.

 

3. Are you using a phone browser or a desktop(regular) browser to view the webstream.

<Lakshman> Laptop

      Lakshman_DSP  thanks for sharing the details.  When you switch between networks which results in a change of IP there can be issues in live streaming. Can you try the below workaround and let us know if it works.

       

      How do I update the WebStreamModule IP address if the IP address of my camera changes?

      To change the WebStreamModule IP address:

      1. In Azure Portal, go to IoT Hub > Iot Edge > select your IoT device > Set Modules > Configure (next to WebStreamModule)

      2. Change the environment variable RTSP_IP field to match the current IP address of the camera device.

        PuneetRaheja 

        I have checked WebStreamModule IP address and observed its different from current camera IP.

        I tried to update WebStreamModule IP address by modifying with latest camera IP but not worked, and observed IP getting restored to old IP later.

         

        I have removed existing IoT edge device from IoT account and added as new IoT edge device with current camera IP. Video live started working in web browser with these changes.

        (Both camera and Laptop connected same network i.e. intranet/sub net)

         

        Please confirm below.

        1. Is it required to add new IoT edge device to IoT hub account every time when we connected new hotspot ? (Updating WebStreamModule IP address not worked in my case).
        2. Observed web live streaming working from single client at a time (Laptop/mobile, Not working multiple web live streaming). Is it known limitation of AI camera or any additional settings required for multiple web live streaming.
        3. Observed more latency in web live streaming compared with VLC/HDMI live streaming. Is there any options or settings to improve web live streaming latency. (I know there are many impact factors for latency but I would like to know is there any options from Camera or Azure end).
        4. Is there any option/possibility to disable existing vision module which is running on camera by default (AIVisionDevKitGetStartedModule) 
        5. Is it internet (Data connection) is mandatory for web live streaming over intranet/subnet. (Assume docker images downloaded already).

        Now I also tried to web live streaming over internet i.e. external network, but not working.

        (Both camera and Laptop connected different hotspots)

        1. Steps/settings for web live streaming from internet i.e. external network.
        2. Steps/procedure for live streaming to popular web services like youtube.
