Low latency streaming capabilities using <availabilityTimeOffset> and partial segments

Created by: smedegaard

My company's use case requires as low latency as possible. Real time would be ideal. Reading the white paper Overhead and Performance of Low Latency Live Streaming using MPEG-DASH made me want to test the capabilities of HTTP 1.1 to handle chunks of segments.

In this paper, we proposed to use the amendment 1 of DASH in combination with Gradual Decoding Refresh encoding and to deliver media frames up to the frame.
— From the conclusion of the white paper

We would love for something like this to be implemented in Dash.js

@bbcrddave mentioned on Slack that returning partial segments could be implemented with fetch API.

Any help and comments on getting this work started is greatly appreciated.
