How to install ffmpeg in a Micro?

[codyandersan]

I am creating a Flask server that can download youtube videos. But for that, I need to install ffmpeg or avconv on my server. Is there a possible way to do that?

My main.py:

from flask import Flask, request, redirect

import logging
from contextlib import redirect_stdout
from io import BytesIO
import yt_dlp

import cloudinary
import cloudinary.uploader

app = Flask(__name__)

@app.route("/")
def hello_world():
    return "Hello World"

def download_bytesio(url):
    ydl_opts = {
        # "format": "best[ext=mp4]",
        "format": "bestvideo[height>=720]+bestaudio/best[height>=720]",
        "outtmpl": "-",
        "logger": logging.getLogger(),
    }
    video = BytesIO()
    with redirect_stdout(video):
        with yt_dlp.YoutubeDL(ydl_opts) as ydl:
            ydl.download(url)
    return video


@app.route("/download")
def download():
    """
    Downloads a video with the link provided in the 'url' argument, and redirects to the cloudinary url
    Sample Request: /download/url=https://youtu.be/tPEE9ZwTmy0
    """
    url = request.args.get('url')
    video = download_bytesio([url])
    video.seek(0)
    response = cloudinary.uploader.upload_large(
        video,
        resource_type="video",
        public_id="video",
        chunk_size=6000000,
    )
    url = response["url"]
    return redirect(url)

My Spacefile:

v: 0
micros:
  - name: python-app
    src: .
    engine: python3.9
    dev: gunicorn main:app
    run: gunicorn main:app

The error I am receiving:

[python-app]     raise DownloadError(message, exc_info)
[python-app] yt_dlp.utils.DownloadError: ERROR: You have requested merging of multiple formats but ffmpeg is not installed. Aborting due to --abort-on-error

Please help..
