iconik Edge Transcoder on CentOS 7

This section contains everything you need to know about installing and managing the iconik Edge Transcoder

1. Download and install the iconik Edge Transcoder

Set up the iconik Yum repository, and install the iconik Edge Transcoder RPM

cd /etc/yum.repos.d
sudo wget
sudo yum install iconik_edge_transcoder

It will be installed in /opt/cantemo/iconik_edge_transcoder where you will also find the config file called config.ini

For local transcoding to work you will have to install ffmpeg, poppler and ImageMagick. Make sure they are in the path for the user running the service.

Below is one way of doing so, but please do not use on a production setup without checking compatibility with other software:

sudo yum install epel-release -y
sudo yum update -y
sudo rpm -Uvh
sudo yum install ffmpeg ffmpeg-devel ImageMagick poppler-utils ghostscript ufraw -y

Alternatively, you can download a static build of ffmpeg which doesn't require any additional libraries. This is available from

To get frame accurate playback in other browsers than Safari you also need mp4mux from Bento4

You can download binaries from but the latest version does not work properly on CentOS 7. Please use the version available at instead.

Unpack the correct package, and copy the mp4mux binary to /usr/local/bin

2. Edit config.ini

Edit config.ini to look like this (See Setting up how to get the correct values)


app-id = 22f34c6e-268e-11e7-ac53-6c4008b85488
iconik-url =
auth-token = eyJhbGciOiJIUzI1NiIsImlhdCI6MTUwMTU3NjAyNCwiZXhwIjoxNTAxNjE5MjI0fQ.eyJpZCI6IjMzMjFkMjIyLTc2OTMtMTFlNy1hN2EyLTAyNDIwYTAyMTAxYSJ9.sgag4OQb19J9qT1IAdKZYAqbpIoai7oW60Mahye7o8s
sleep-time = 10
max-transcoding-jobs = 4
log-filename = /var/log/cantemo/iconik_edge_transcoder/default.log

3. Start the service

Iconik Edge Transcoder will add a system user called cantemo that will be used to run systemd service. The cantemo user must have permissions to read/write the storage mount point folder and it contents. You can add the cantemo user to a group to manage permissions on group level instead.

After installation you can start service with:

sudo systemctl enable iconik_edge_transcoder
sudo systemctl start iconik_edge_transcoder

This will create the Transcoder in iconik the first time you start it. You have to add this transcoder to the corresponding storages in the iconik UI for it to work. To check status of the service use:

sudo systemctl status iconik_edge_transcoder

For following the log file, you can use the following command:

sudo tail -f /var/log/cantemo/iconik_edge_transcoder/default.log

You can run also run the systemd service from your custom user providing it to /usr/lib/systemd/system/iconikedgetranscoder.service with passing your own config and log files that are accessible for your custom user. Log file location can also be set in config.


ExecStart=/usr/bin/iconik_edge_transcoder --config=/home/john/iconik_edge_transcoder/config.ini --log-filename=/home/john/iconik_edge_transcoder/default.log

After adding your custom user you need to restart service.

sudo systemctl daemon-reload
sudo systemctl restart iconik_edge_transcoder
