Dash.js V 2.6.8 released with relevant features.
Epic Labs, a proud member of the DASH Industry Forum and Digital Production Partnership (DPP), announces the release of version 2.6.8 of dash.js that incorporates major improvements such as low latency Chunked CMAF support.
Madrid(10 May 2018)
Several enhancements have been incorporated in this new version such as fixes that improve captioning and DRM handling. But above all, two implementations are extremely important, one of them is the support of persistent licenses (DRM), while the other is the introduction of Low latency chunked CMAF over HTTP, which enables 2-4 second latency for live streams keeping a smooth playback experience. Supporting this feature in a scalable manner is enabled by major CDNs such as Akamai.
The development aims to provide an alternative to older protocols like RTMP whose main advantage over HTTP streaming ones was its lower latency.
In the client side, part of the solution is based on the use of the fetch API offered by browsers, which allows reading incoming chunks as they arrive, instead of waiting for them to be completed. Dash.js analyzes the byte stream representing each chunk and pushes it to the video decoder as soon as it has enough information to start playback stably. Every player based on dash.js is able to benefit of this new feature by doing nothing but updating to the latest version.
Jesús Oliva, Epic Labs Media Engineer Lead & Founder: “This is an exciting achievement because it provides a low latency chunked solution based on open standards, protocols and source code. A real alternative to proprietary or custom solutions that require to package content in a strange manner or exceed the norm. This is a great deal for the industry.”
