In the early days of the web, the only thing that mattered was getting that content out to users no matter how long it took or what resources it consumed. As a matter of fact, users seemed to understand and were ready to wait till whenever their browser's loading spinner stops and the contents displayed.
Update:In this post, we clarify that not all browsers natively support HLS or MPEG-DASH, and thus in order to deliver adaptive streaming video to all devices, you should deliver it using a video player that supports your chosen format. In December of 2017, Cloudinary released its own Video Player, which enables you to easily embed a player in your web page that can stream any HLS or MPEG-DASH video. For details, see the Video Player announcement blog post and the Video Player documentation.
