Disclaimer

This project is a fork of adrianblynch/flac-to-mp3 original project. The name of the variable FlacConverter in the usage section, reflect this origins until a complete wrapping of the ffmpeg will be completed.

This is an ultra-wide learning project, doesn't aim to be a complete-ready-to-use-ffmpeg-wrapper, but this want to give to contributors the opportunity to master:

• To analyze and implement software components
• Node's feature (like child process, stream and promise)
• Building with CI
• Testing and Coverage
• Useful tools (npm, vs code)
• Managing enviroments
• and much more..

Installation

npm install ffmpeg-wrapper

      })
      .catch((err) => {
        // An error occured
