As a part of the smart city initiatives, Hyderabad (GHMC), one of the largest cities in southern India is working on capturing massive volumes of video streams 24/7 captured from the large numbers of “Vivotek IB9371 – HT” cameras installed at traffic lights, parking lots, shopping malls, and just about every public venue to help solve traffic problems, help prevent crime, dispatch emergency responders, and much more. GHMC uses AWS to host their entire infrastructure.
The camera’s write stream into Kinesis Video Stream securely and eventually consumed by applications for custom video processing, on-demand video playback and also consumed by AWS Rekognition for video analytics. The data is consumed to fulfill 2 requirements
Kinesis Video Stream is accessed for live playback and to view archived videos (minimum latency of 5-10 seconds) to inspect by the Investigation team
Kinesis Video Stream is accessed for live streaming by Operations and Monitoring team to monitor (low latency, almost near real-time)
How can this be achieved? select 2 options.

Answer options:

A.Operations and Monitoring team use application using HLS (HTTP Live Streaming) to access videos to monitor live situation
B. Investigation team use application using HLS (HTTP Live Streaming) to access videos to inspect by replay videos and view identified archived videos
C.Operations and Monitoring team use application using ‘GetMedia’ API, along with Stream Parser Library to access videos to monitor live situation
D.Investigation team use application using ‘GetMedia’ API, along with Stream Parser Library to access videos to inspect by replay videos and view identified archived videos

Answer: B,C
Option A is incorrect -HTTP Live Streaming (HLS) is an industry-standard HTTP-based media streaming communications protocol. You can use HLS to view an Amazon Kinesis Video Stream, either for live playback or to view archived video. You can use HLS for live playback. Latency is typically between 3 and 5 seconds, but it can be between 1 and 10 seconds, depending on the use case, player, and network conditions

Option C is correct -You use the GetMedia API to build your own applications to process Kinesis Video Streams. GetMedia is a real-time API with low latency. If you want to create a player that uses GetMedia, you have to build it yourself.
