Image from store Adaptive Bitrate Manifest Viewer
Description from store 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 CHANGELOG =========== 2018-03-26 0.9.1 Fixed an issue where URIs with equal signs in them wouldn't get replaced. 2018-01-29 0.9.0 Added ability to handle MPEG Dash and SMIL formats as well. Better handling of 404 and SSL certificate issues on manifest request. Major contributions made by my friend Joe Greathead. 2017-12-18 0.8.5 Excluding a few more domains reportedly having issues with this extension. 2017-06-19 0.8.4 Fixed bug where URIs in tags were incorrectly hyperlinked. 2017-05-11 0.8.3 Excluding http://video-dev.github.io/hls.js/demo/ to avoid causing issues. 2017-05-04 0.8.2 added a few more tags to the pattern and definitions list.

  • (2020-03-03, v:0.9.1) Martin Fillafer: XML formatting
    Hello Mike, this is really nice little tool! Would be great if it could format the XML (MPD) like the preview in the Chrome network tab.

    I used to love this extension, but some change occurred recently and it now hangs regularly, and I'm unable to use my browser at all until I kill it.
  • (2019-07-02, v:0.9.1) Emad Mahdi: Problem with some urls such as google search
    Hello, thanks for this extension but i have problem when searching google for something like this "index.m3u8" this will cause google search not to respond anymore !!!
  • (2018-10-04, v:0.9.1) Jared Bennett: HLS URL Identification Error
    Hi Mike, If ".m3u" is included in a query parameter, not the file path, it will open the extension viewer. This causes problems when you have the manifest url specified in query parameters, such as the way some demo players work. Example: https://www.google.com/?.m3u
  • (2018-09-09, v:0.9.1) how it works?

  • (2018-01-04, v:0.8.5) Andrea Baiardi: m3u list
    Hi, just installed but no way playing m3u list, any idea, please? Thanks. Andrea
  • (2017-07-25, v:0.8.4) Florian He: DASH (.mpd) Manifests
    Hey Mike, would be really nice if the would also support MPEG-DASH Manifest Files. Chrome has no function to view any files just as text-files like Firefox is doing just by using "view-source:" infront of the URL. So analysing any Manifest like .m3u8 or .mpd is more clicks away because they need to download. Your tool is really nice for that. To add .mpd DASH-Manifests would make it nicer :-) Thanks and best regards...
