Building and Usage

Due to legal implications arising from the patents around the AVC/h264 format, we cannot provide and distribute pre-built Docker images. Therefore, we provide the build instructions in a Dockerfile that can be easily integrated in a docker-compose.yml file.

To run this microservice using docker-compose, you can use the following docker-compose.yml file to let Docker build this software for you:

version: '2'
services:
    rec2csv_png:
        build:
            context: https://github.com/chalmers-revere/rec2csv-png.git
            dockerfile: Dockerfile.amd64
        restart: on-failure
        volumes:
        - .:/opt/data
        working_dir: /opt/data
        command: "--rec=YourRecording.rec --odvd=YourMessageSpec.odvd"

When you built your Docker image named transcoder, you can also call it as follows:

docker run --rm -ti --init -v $PWD:/opt/data -w /opt/data transcoder --rec=YourRecording.rec --odvd=YourMessageSpec.odvd

The current folder . is shared into the Docker container to access the recording file YourRecording.rec and the message specification file YourMessageSpec.odvd.
