Adding this event handler solved my issue. Process is stopped crashing, just print the error

ffmpeg.stdin.on('error', (stdinError: any) => {
                    // This error means ffmpeg's stdin pipe closed unexpectedly.
                    cleanup(true, new Error(`FFmpeg stdin error: ${stdinError.message}`));
                });

Now in logs I see something like this:

Failed to get replay gain volume of the audio file Error: FFmpeg stdin error: write EPIPE
