I need to take an input stream's audio and another stream's video and combine them with fluent-ffmpeg. I am using nodejs. Also, I need to pipe the output. Both of the inputs have video and audio, but I need to merge a stream's audio only, while doing the same with video on the other stream.
Thank you.

you don't need to use fluent-ffmpeg, if you have ffmpeg installed on your machine you can use child-process.
const {exec} = require("child_process");
const command = "ffmpeg -i video.mp4 -i audio.wav -c:v copy -c:a aac output.mp4"
I got this command from how to combine audio and video using ffmpeg
exec(command, (error, stdout, stderr) => {
if (error) {
console.error(`exec error: ${error}`);
return;
}
console.log(`stdout: ${stdout}`);
console.error(`stderr: ${stderr}`);
})
;
