hls-cmcd

Node library to decorate HLS with some CTA-5004 CMCD query params.

Example of use case is to use this library in a proxy that decorates an HLS with CMCD query parameters, in those cases where that is preferred (credit to Anders Näsman/Akamai for the idea).

Adds the following tags when information is available:

• br (Encoded Bitrate): based on bandwidth declaration in multivariant manifest. Added to the media playlist URL in the multivariant manifest.
• d (Object Duration): based on segment duration declared in media playlist. Added to the segment URLs in a media playlist.
• nor (Next Object Request): TBD
• ot (Object Type): Added as m to the media playlist URL in the multivariant manifest.

Example

const { DecoratedHls } = require("@eyevinn/hls-cmcd");

const response = await fetch(url);
if (response.ok) {
    const hls = new DecoratedHls(response.body);
    const m3u = await hls.decorate();
    console.log(m3u.toString());
}
