AWS Elemental MediaStore now supports chunked object transfer , a standard that lets you build ultra-low latency end-to-end workflows for over-the-top (OTT) video. When using chunked object transfer to deliver segmented objects, your video segments are split into smaller chunks that can be played before the complete segment is delivered. Video players can begin playback by requesting video from CDNs such as Amazon CloudFront , which in turn can start downloading the beginning of a video segment from MediaStore while the encoder is still in the process of writing the end of that same segment.
