How to use streams with FFMPEG and Node

I am interested in using ffmpeg with node. I have looked at the many libraries available (such as fluent-ffmpeg), but they are not what I'm looking for.

I would like to know if there is a way to execute FFMPEG with node, but instead of creating a file, transfering everything to a stream. I don't want to use disc space for 'reasons' and it would make more sense for my application to execute a command and pipe that audio/video into a node stream instead.

Is there a way to do this? If so, what's my best bet?

Yes, this is really easy as a child process.

If you use a hyphen - for an input or output filename, it will allow you to pipe with STDIN or STDOUT. Therefore, you just need to do something like this:

const ffmpeg = child_process.spawn('ffmpeg', [
  '-i', '-',
  // Some other parameters here
  '-'
]);

You can use ffmpeg.stdin and ffmpeg.stdout here.
