What is Adaptive Bitrate Manifest Viewer?

Adaptive Bitrate Manifest Viewer is a chrome extension that lets you view HLS m3u8, MPEG Dash and SMIL manifests directly in your Chrome browser. This tool conveniently blocks the download when the manifest is requested as the main URL, parses it and displays it, complete with syntax highlighting and direct links to the documentation. Ideal for developers and testers, it also provides the option to download the manifest file and links the resources in the manifest for easy testing.

Extension summary

Analyze keywords

Avoid having to download the manifest file and then open in a text editor just to view it.

The extension works by blocking the download when the manifest is requested as the main url and then parses and displays it. Some syntax highlighting and definition links to the ietf.org draft documentation. To download the manifest file, click on the source url at the top of the page. Resources are linked in the manifest to make it easy to test the different parts.

You can test it out using a sample manifest url like https://bitdash-a.akamaihd.net/content/MI201109210084_1/m3u8s/f08e80da-bf1d-4e3d-8899-f0f6155f6efa.m3u8
