Media Speed Control

This extension allows users to adjust the playback rate of HTML5 video and audio elements. It also features a strict mode which enables users to overwrite the default behaviour of media players that might try to reset the playback rate. This extension works for Chromium based browsers and Mozilla Firefox.

Setup

• Chromium based browsers (Google Chrome, Microsoft Edge, Opera, Vivaldi, etc.):

  1. Type chrome://extensions in the address bar. (If you use a browser other than Google Chrome, it will redirect you automatically.)
  2. Enable the Developer mode temporarily.
  3. Click Load unpacked extension... and select the extension's folder.

• Firefox:

  1. Delete the manifest.json file and rename manifest_firefox.json to manifest.json.
  2. Type about:debugging#/runtime/this-firefox in the address bar.
  3. Click Load Temporary Add-on and select the manifest.json from the extension's folder.

  Remarkable Notes: Extensions which are installed this way only remain installed until Firefox restarts. Also, Firefox only supports sound for playback rates which are not higher than 4 times the regular playback rate.

TODOs/ ideas for possible future implementations

• add options page to change and save personal settings
• add keylisteners to control the playback rate
