Amazon Kinesis Video Streams | Console Flashcards
If I have a custom processing application that needs to use the frames (and fragments) carried by the Kinesis video stream, how do I do that?

In general, if you want to consume video streams and then manipulate them to fit your custom application’s needs, then there are two key steps to consider. First, get the bytes in a frame from the formatted stream vended by the GetMedia API. You can use the stream parser library to get the frame objects. Next, get the metadata necessary to decode a frame such as the pixel height, width, codec id, and codec private data. Such metadata is embedded in the track elements. The parser library makes extracting this information easier by providing helper classes to collect the track information for a fragment.
The steps after this are highly application dependent. You may wish to decode frames, format them for a playback engine, transcode them for content distribution, or feed them into a custom deep learning application format. The Kinesis Video Streams stream parser library is open-sourced so that you can extend it for your specific use cases.
What is the Kinesis Video Streams management console?

The Kinesis Video Streams management console enables you to create, update, manage, and monitor your video streams. It console can also playback your media streams live or on an on-demand basis, as long as the content in the streams is in the supported media type. Using the player controls, you can view the live stream, skip forwards or backwards 10 seconds, use the date and time picker to rewind to a point in the past when you have set the corresponding retention period for the video stream. The Kinesis Video Streams management console’s video playback capabilities are offered as a quick diagnostic tool for development and test scenarios for developers as they build solutions using Kinesis Video Streams.
What media type does the console support?

The only supported video media type for playback in the Kinesis Video Streams management console is the popular H.264 format. This media format has wide support on devices, hardware and software encoders and playback engines. While, you can ingest any variety of video, audio, or other custom time-encoded data types for your own consumer applications and use cases, the management console will not perform playback of those other data types.
