Audio Test filter_html5avtomp4 - Record short audio messages

The Atto text editor allows teachers and students to record short audio messages directly into the editor. The default audio format is ogg (which cannot be changed in either the browser or Moodle).

The filter in the Moodle plugins directory: HTML5 audio/video to MP4 filter (moodle.org) can be used.

This filter allows the automated creation of MP4 sources for HTML5 <audio> and <video> elements. ... This plugin then check for the existence of an mp4 source and provides it automatically if it exists. In the case the mp4source does not exist, it is created via a scheduled task. Requirements: A working ffmpeg installation, and the correct path to be set in the plugin settings.
