Mootranscode provided local audio and video transcoding for Moodle. It replaces the uploaded version of video and audio files with transcoded versions that can play anywhere. This avoids students needing to be able to view every possible format, like requiring QuickTime for MOV files on Windows.
The following conversions are currently done:
- video/quicktime (.mov) to MP4 video
- audio/ogg (.ogg) to MP4 audio
The MP4 versions of the files should work on any modern platform.
This was created as a one-off to solve a particular problem. Your mileage may vary but contributions are always very welcome.
This application has only been tested with Moodle 3.10 running on Ubuntu with PostgreSQL serving the database.
ffmpeg must be installed to do the heavy lifting.
Compile the code with
$ cargo build --release
then move the binary from target/release/mootrancode to somewhere convenient
like /usr/local/bin/.
To run the application as a service using systemd create a file called
/etc/systemd/system/mootranscode.service substituting the name of the
appropriate user:
[Unit]
Description=Mootranscode
After=network.target
StartLimitIntervalSec=0[Service]
Type=simple
Restart=always
RestartSec=1
User=YOUR_USERNAME
ExecStart=/usr/local/bin/mootranscode --repeat
[Install]
WantedBy=multi-user.target
Start the service using:
# systemctl start mootranscode
Set the service to start a boot using:
# systemctl enable mootranscode
The application must be able to read and write files in the Moodle data
directory and that the server can read. This may require running as a user
such as moodle or one in the www-data group.
By default the application runs once and exits. Continuosly poll the database
for new files by using the --repeat option.
Unless the current user can connect to the Moodle database without password
authentication you will need the --dbpass option.
For a full list of options run:
$ mootranscode -help
