A wrapper for an emscripted version of ffmpeg to extract the audio tracks from media containers. It includes custom builds for 'wav'.
npm install --save sonarvio-converter
- minimal API surface for '.exec', '.info' and '.transform'
- automatic queue system for scheduling re-used workers
- transparent migration for usage with proxy for CORS handling
For a better integration with existing projects using webpack the actual script files for the workers are excluded. They have to be provided as an argument through the constructor.
