Video Trasncoding Queue with Web UI. Currently it only tries to transcode every video to webm

palomitas-transcoder

This project uses Docker and docker-compose to manage the parts of the application.

Run docker-compose build once to build the docker images and then run docker-compose up to start the redis container and the node container.

You can start a development version that listens for changes in the files with the command docker-compose -f docker-compose.dev.yml. In order for this to work, a .env file must be located in the root of the project with at least the content of the .env.prod file.

This only starts the backend part of the project, listening on port 4000. To start the Web UI you nedd to cd into the www folder, run npm install (only once to create the node_modules folder) and run npm start. The web will be located on http://localhost:3000
