Before installing MainConcept 2GO, please ensure Docker is installed correctly.
To download and install Docker on your server, please follow the instructions here: www.docker.com/community-edition
After successful installation you should be able to run the Docker “hello-world” container. Example output from the Docker hello-world container:
$ docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64)
3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal.
If you see different output, please refer to the Docker installation guide.
Resources for Docker
On Windows machines there is a default limitation of resources available for Docker. It could be adjusted in the "Settings > Advanced" section. For more information, please check the official website: docs.docker.com/docker-for-windows.

- AAC-HEv1 (up to 5.1 channels)
- AAC-HE v2 (stereo)
Several built-in presets are included in the product for direct usage.
If you need to manually tune presets there is an *.mps file for each built-in preset located in the “volume/presets”. To specify a manually edited preset, use the PRESET parameter.
With Docker installed, most of the MainConcept 2GO configuration is complete. However, some 2GO products require shared folders or specific parameters at startup.
The REST API in MainConcept 2GO is described in separate documentation. Click here to open the REST API user guide.
Configuring shared folders
To read and write files located on the host computer, MainConcept 2GO uses shared volumes to access the file system of the host. Docker uses mounted volumes to share host folders with 2GO containers.
The “run” convenience script in the scripts folder runs the MainConcept 2GO container and automatically maps the required folders from your host computer in to the 2GO container.
Starting MainConcept 2GO
Make sure you have successfully installed your MainConcept 2GO product on the computer by following the Installation instructions.
The “run” script inside the scripts folder makes starting MainConcept 2GO easy and lets you understand how 2GO docker containers are actually run. If you plan to run MainConcept 2GO through container management tools like Docker Compose, Kubernetes or Docker Swarm, it is recommended that you understand the parameters required for 2GO containers by reading the “run” script.
MainConcept 2GO products require passing configuration parameters to the container at startup. These can include input and output filenames, serial keys, shared volume folders or external URLs. These parameters can be specified in a JSON file, a properties file or via the command line.
Using job description file
MainConcept 2GO v2.0 introduces a REST API and provides users an interface that is more suitable for integration with their existing environment or tools. This API covers functionality to create jobs and query their status using standard REST API calls over HTTP. A job description file is posted to the endpoint, which must be in JSON format. This JSON file must contain all the necessary parameters required for the submitted jobs.
|INPUT||8MBit.mp4||Source filename for audio conversion; must be in or under SHARED_PATH_IN|
|OUTPUT||out_8Mbit.mp4||Target filename for encoded output; you also need to add the file extension; must be in or under SHARED_PATH_OUT
File Extension: *.mp4
|PRESETNAME||MC2Go_AAC_2ch_he_128kbps||Preset name for AAC conversion when using original MainConcept preset(s) included with the Docker container. Note: When PRESETNAME is used, PRESET must not be used.|
|PRESET||<folder_in_shared_path>/MC2Go_AAC_2ch_he_128kbps.mps||Custom preset file(s) (MPS); must be in or under SHARED_PATH_IN volume outside of the Docker container. Note: When PRESET is used, PRESETNAME must not be used.|
|VERBOSITY||SILENT||Sets verbose level. Available options are:
|KEEP_CONTENT||FALSE||Prevents deletion of temporary content (e.g. downloaded, transcoded). Default value is FALSE.|
To edit the parameters of the JSON file, use a text editor. Here are some examples:
Using properties file
The easiest way to start MainConcept 2GO is by editing the “properties.txt” file to your needs and then call the “run” script with this properties file.
~/MainConcept/2GO/mc_2go_aac_audio_converter_demo# ./scripts/run.sh scripts/properties.txt
The MainConcept 2GO AAC Audio Converter supports the following configuration options:
|SHARED_PATH_IN||/path/source_folder||Optional: Folder where the input file is located|
|SHARED_PATH_OUT||/path/target_folder||Optional: Folder for the encoded output file|
|JOBS||/path/to/json_file||Optional: Specify a job JSON file for immediate processing|
|PORT||8082||Specify port for REST API.. Default value is 8080.|
|AUTOSTART||TRUE, FALSE||Disable/enable job queue processing when Docker runs. FALSE sets the service to a stopped state after the Docker runs. Default value is FALSE|
|VERBOSITY||SILENT||Sets verbose level. Available options are:
SILENT (0) - Prints only error messages
DEFAULT (1) - Default level if verbose level is not specified. Prints information about input file, output file, preset. Prints information about REST API calls (target URLs with parameters, no BODY info).
FULL (2) - Prints all available information, including processing status, file transfer, REST API calls (target URLs with parameters with BODY info), complete information from processing step.
To edit the parameters, use a text editor:
Using command line options
Instead of editing a properties file, all configuration parameters can also be specified on the command line directly.
~/MainConcept/2GO/mc_2go_aac_audio_converter_demo/docker# ./scripts/run.sh \
> ACCEPT_EULA=Y \
> SHARED_PATH_IN=~/MainConcept/2GO/mc_2go_aac_audio_converter_demo/volume \
> SHARED_PATH_OUT=~/MainConcept/2GO/mc_2go_aac_audio_converter_demo/volume \
> JOBS=~/path/to/json_file \
> PORT=8082 \
> AUTOSTART=TRUE \
> CUSTOMER_ID=xxx \
Docker Compose lets you start multiple replicas of the same image. It also significantly simplifies starting MainConcept 2GO products.
Docker Compose is a separate tool that must be installed in addition to Docker. Please refer to the documentation about how to install and setup Compose: docs.docker.com/compose/
To run MainConcept 2GO with Docker Compose, you create a compose file in YAML. All parameters to run the 2GO product via Docker Compose are specified inside this YAML file. To simplify deployment of MainConcept 2GO containers, setting environment variables for the 2GO configuration and then using them in the YAML file is recommended.
This is a basic “docker-compose.yml” file showing how to configure MainConcept 2GO:
1 version: '2.2'
4 image: 2go_aac_audio_converter_demo
5 network_mode: host
It uses two environment variables: 2GO_VOLUME and 2GO_PARAMS. These must be set before starting docker-compose.
~# export 2GO_VOLUME=~/MainConcept/2GO/mc_2go_aac_audio_converter_demo/volume/
~# export 2GO_PARAMS="INPUT=avchd_camera_testfile.mts OUTPUT=out_file PRESETNAME=AAC_2ch_he_128kbps CUSTOMER_ID=xxx"
After that starting 2GO using Docker Compose is as easy as:
~/MainConcept/2GO/mc_2go_aac_audio_converter_demo# docker-compose up -d
Starting mc2goaacaudioconverterdemo_2go_1 ...
Starting mc2goaacaudioconverterdemo_2go_1 ... done
Stopping MainConcept 2GO execution
MainConcept 2GO containers should be stopped using the convenience “stop” script provided in the scripts folder.
To execute the script on an active container, you first need to know the container ID. This can be found from the first column of the docker ps command:
~/MainConcept/2GO/mc_2go_aac_audio_converter_demo# docker ps
CONTAINER ID IMAGE COMMAND CREATED
bc45686deb0e mc_2go_aac_audio_converter_demo "/opt/bin/reporting_..." 4seconds ago
Then use the convenience “stop” script in the scripts folder to abort the 2GO execution:
~/MainConcept/2GO/mc_2go_aac_audio_converter_demo# ./scripts/stop.sh bc45686deb0e
Stopping the AAC Audio Converter...
AAC Audio Converter stopped.
