Greengrass Kinesis Video Pause Stream

Question

Hello,

I have a Greengrass Core Device with an IP camera connected and the Kinesis component running on the device for viewing the video stream from AWS Kinesis Video Streams. This device has 3G mobile network connectivity. My question is if there is a way to only send the video stream on demand or pause the video sending, in order to reduce data consumption.

Thank you very much in advance.

Best regards

Alberto

Hi there,

I have a quite similar system but using WiFi communications instead of 3G. In any case, I would like to reduce the network consumption since I have some lag problems with other devices (the camera is using almost all the bandwidth), is anyone facing this situation and has found any workaround / solution?

Thanks beforehand, looking forward to hearing from you.

Kind regards.

Daniel.

Answer

I would recommend looking at the usage of additional AWS IoT capabilities which can support you in the control of the device to pause and re-start the video on demand. In order to do so, you may want to look at the usage of AWS IoT Shadow Service which can be nicely integrated in Greengrass using the Shadow Manager component which synchronises with the cloud side AWS IoT Core shadow of the specific device. Here you can find more details:
https://docs.aws.amazon.com/greengrass/v2/developerguide/interact-with-shadows.html

Through the usage of the Shadow service, you can issue commands to the device and when the device can consume them report the acknowledgment when done. In addition to that you could build your own Greengrass component to handle the starting and stopping of the camera stream whenever the command is received on the shadow.

Do you have battery constraints to consider?
