Build the Frame Extractor Docker image

Extracting frames and audio from a video is achieved with ffmpeg. ffmpeg is not available to an Cloud Functions action written in JavaScript or Swift. Fortunately Cloud Functions allows to write an action as a Docker image and can retrieve this image from Docker Hub.

To build the extractor image, follow these steps:

  1. Change to the processing/extractor directory.

  2. Ensure your Docker environment works and that you have logged in Docker hub. To login use docker login.

  3. Run

./buildAndPush.sh youruserid/yourimagename

Note: On some systems this command needs to be run with sudo.

  1. After a while, your image will be available in Docker Hub, ready for Cloud Functions.

  2. Change the DOCKER_EXTRACTOR_NAME environment variable property in the Deploy stage of the toolchain and run the stage to use the new image.
