Before installing MainConcept 2GO please make sure Docker is installed correctly and the hello-world example from Docker is executed corrected.

Installing Docker

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.

With Docker installed most of the MainConcept 2GO configuration is done. However, some 2GO products require shared folders, or specific parameters at startup.

Configuring shared folders

To read and write files located on the host computer, MainConcept 2GO is using shared volumes to access the filesystem of the host. Docker uses mounted volumes to share host folders with 2GO containers. The convenience script inside the scripts folder to run the MainConcept 2GO container, automatically maps the required folders from your host computer to the 2GO container.

Configuration options

MainConcept 2GO Proxy File Generator supports the following configuration options:

Option Sample value Description
ACCEPT_EULA Y The MainConcept End-User License Agreement (EULA) must be accepted before MainConcept 2Go can start. The license terms for this product can be found in provided package.
SHARED_PATH_IN /path/source_folder Folder where the input file is located
SHARED_PATH_OUT /path/target_folder Folder for the encoded output file
INPUT 0002CD.MXF Source filename for audio conversion; must be in or under SHARED_PATH_IN
OUTPUT out_sd_25fps Target filename for encoded output; the file extension will be created by 2GO; must be in or under SHARED_PATH_OUT
PRESETNAME AVC_AAC_SD_25fps_3mbit Preset name for proxy generation when using MainConcept original preset(s) included in the Docker container. Note: When PRESETNAME is used, PRESET must not be used.
PRESET <folder_in_shared_path>/AVC_AAC_CIF_25fps_600kbit.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.
CUSTOMER_ID Unique customer identifier provided by MainConcept. Customer ID parameter can be also represented as `CID`
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 out the copyright/version information
- FULL (2) - Higher verbose level. Prints all available information including command-line parameters INPUT / OUTPUT / PRESETS / SERIAL


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” scripts.

MainConcept 2GO products require configuration parameters at container startup. This can include input and output filenames, serial keys, shared volume folders or external URLs. These parameters can be specified in a properties file or on command line.

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_proxy_file_generator_demo# ./scripts/run.sh scripts/properties.txt

To edit the parameters, use a text editor:

2  SHARED_PATH_IN=~/MainConcept/2GO/mc_2go_ proxy_file_generator_demo/volume
3  SHARED_PATH_OUT=~/MainConcept/2GO/mc_2go_ proxy_file_generator_demo/volume
5  OUTPUT=output_file
6  PRESET=AVC_AAC_SD_25fps_3mbit

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 \
>    SHARED_PATH_IN=~/MainConcept/2GO/mc_2go_proxy_file_generator_demo/volume \
>    SHARED_PATH_OUT=~/MainConcept/2GO/mc_2go_proxy_file_generator_demo/volume \
>    INPUT=0002CD.MXF \
>    OUTPUT=out_file \
>    PRESETNAME=AVC_AAC_SD_25fps_3mbit \
>    CUSTOMER_ID=xxx \

Using docker-compose
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 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 are specified inside the YAML file for Docker Compose. To simplify deployment of MainConcept 2GO containers it is recommended to set environment variables for the 2GO configuration and then use these variables in the YAML file.

This is a basic “docker-compose.yml” file showing how to configure MainConcept 2GO.

1  version: '2.2'
2  services:
3    2go:
4      image: 2go_proxy_file_generator_demo
5      network_mode: host
6      volumes:
7      -${2GO_VOLUME}:/volume
8      environment:
9      -2GO_PARAMS=${2GO_PARAMS}

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_proxy_file_generator_demo/volume/
~# export 2GO_PARAMS="INPUT= 0002CD.MXF OUTPUT=out_file QUALITY=low CUSTOMER_ID=xxx"

After that starting 2GO using Docker Compose is as easy as:

~/MainConcept/2GO/mc_2go_proxy_file_generatordemo# docker-compose up -d
Starting mc2goproxyfilegeneratordemo_2go_1 ...
Starting mc2goproxyfilegeneratordemo_2go_1 ... done

Stopping MainConcept 2GO execution

It is recommended to execute a script inside the MainConcept 2GO container in order to stop execution properly.

To execute a script in an active container you first need to know the container ID from the first column of the docker ps command:

~/MainConcept/2GO/mc_2go_proxy_file_generator_demo# docker ps
CONTAINER ID   IMAGE                              COMMAND                    CREATED
bc45686deb0e   mc_2go_proxy_file_generator_demo   "/opt/bin/reporting_..."   4seconds ago

Then use the convenience “stop” script in the scripts folder to abort 2GO execution:

~/MainConcept/2GO/mc_2go_proxy_file_generator_demo# ./scripts/stop.sh bc45686deb0e
Stopping the Proxy File Generator...
Proxy File Generator stopped.
~/MainConcept/2GO/mc_2go_proxy_file_generator_demo# █
