An IoT company has a new product which is a camera device. The device has installed several sensors and can record video as required. The device has AWS Kinesis Video Streams SDK in the software and can transmit recorded video in real-time to AWS Kinesis. Then the end-users can use a desktop or web client to view, download, or share the video stream. The client app should be simple and use a third-party player such as Google Shaka Player to display the video stream from Kinesis. How should the client app be designed?

Answer options:

A.The client can use HTTP Live Streaming (HLS) for live playback. Use GetMedia API to process and play Kinesis video streams.
B.The client can use HLS for live playback. Use GetHLSStreamingSessionURL API to retrieve the HLS streaming session URL, then provide the URL to the video player.
C.The client can use Adobe HTTP Dynamic Streaming (HDS) for live playback. Use GetHDSStreamingSessionURL API to retrieve the HDS streaming session URL, then provide the URL to the video player.
D.The client can use Microsoft Smooth Streaming (MSS) for live playback. Use GetMSSStreaming API to retrieve the MSS streaming to the video player.

Correct Answer – B
 
The most straightforward way to view or live playback the video in Kinesis Video Streams is by using HLS. HTTP Live Streaming (HLS) is an industry-standard HTTP-based media streaming communications protocol.
Option A is incorrect: Because although GetMedia API may work, it is not as simple as HLS. You may have to create a player that uses GetMedia and build it yourself. However, in this case, a third-party player is needed. Reference is in https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/how-hls.html#how-hls-ex1-session.
Option B is CORRECT: Because GetHLSStreamingSessionURL API is required for third-party players to play the HLS streams.
Option C is incorrect: Because HTTP Live Streaming (HLS) should be used to playback the Kinesis Video Streams.
Option D is incorrect: Same reason as Option
C.
