When the SIGKILL is sent the process does not exit.

[JaroslawPokropinski]

When the SIGKILL is sent the process does not exit. I tried using stream as an input.
I tried downgrading to 2.0.1 where I get an error but the process does not finish anyways.

Version information

• fluent-ffmpeg version: 2.1.3
• ffmpeg version: 7.1
• OS: Windows 11

Code to reproduce

const command = ffmpeg(this.streamUrl)
      .on("error", (error) => console.log(`Encoding Error: ${error.message}`))
      .on("end", () => console.log("Video Transcoding succeeded !"))
      .save(filePath);

  setTimeout(() => {
    command.kill("SIGKILL");
    console.log(`Saved recording`);
  }, 500);

(note: if the problem only happens with some inputs, include a link to such an input file)

Expected results

The process is killed, an error is thrown.

Observed results

No error is caught, the process is still alive and the file is still written to.

Checklist

• I have read the FAQ
• I tried the same with command line ffmpeg and it works correctly (hint: if the problem also happens this way, this is an ffmpeg problem and you're not reporting it to the right place)
• I have included full stderr/stdout output from ffmpeg

After looking a little bit further it seems that this version of ffmpeg spawns a process group and only one of the processes dies on kill.
As a workaround i used spawn and the solution suggested here: https://medium.com/@almenon214/killing-processes-with-node-772ffdd19aad
