exec, abort signal

[abernier]

I know there is global ffmpeg.terminate, but is there a way (maybe using send?) to "abort" a single ffmpeg.exec(cmd) ?

It can for ex be an AbortController signal like in fetch:

const controller = new AbortController();
ffmpeg.exec(cmd, -1, {
  signal: controller.signal
})

// later...
controller.abort();

Maybe we could pass the signal to the centralised FFmpeg.prototype.#send method with a 3rd parameter?

Question: is this expected to also terminate a running exec? Or is the user expected to call ffmpeg.terminate manually? Currently, termination is manual
