Moodle HTML5 audio/video to MP4 filter

This filter allows the automated creation of MP4 sources for HTML5 <audio> and <video> elements.

This is particularly useful if some users are using atto_recordrtc because most browsers create ogg files for audio and webm files for video, which are not playable in Safari.

This plugin then checks for the existence of an mp4 source in the same file area and provides it automatically if it exists. In the case the mp4 source 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.

In Debian-like GNU/Linux environments, ffmpeg can be installed by issuing the following command:

apt-get install ffmpeg

Installation

You need to at least:

1. install ffmpeg (see above),
2. set the pathtoffmpeg in the plugin settings.

Optionnally you can:

• change the other plugin settings as required,
• tweak the execution times of the scheduled task running the file conversions.

Hints:

• Read https://docs.moodle.org/en/Managing_filters how to activate and order filters.
• The order in which the HTML5 audio/video to MP4 filter is placed has an effect on its correct working (whether it converts or not).
• The filter HTML5 audio/video to MP4 filter should be placed at least before filters Convert URLs into links and images and Multimedia plugins.
