import os


app = Flask(__name__)


# Set the download path to a folder inside the current directory

DOWNLOAD_PATH = os.path.join(os.getcwd(), "downloads")


if not os.path.exists(DOWNLOAD_PATH):

    os.makedirs(DOWNLOAD_PATH)


def download_video(url, format_code):

    if format_code == "mp3":

        ydl_opts = {

            "format": "bestaudio/best",

            "outtmpl": f"{DOWNLOAD_PATH}/%(title)s.%(ext)s",

            "postprocessors": [{

                "key": "FFmpegExtractAudio",

                "preferredcodec": "mp3",

                "preferredquality": "192",

            }],

        }

    else:

        ydl_opts = {

            "format": f"bestvideo[height<={format_code}]+bestaudio/best",

            "outtmpl": f"{DOWNLOAD_PATH}/%(title)s.%(ext)s",

            "merge_output_format": "mp4",

            "noplaylist": True,

        }


    with yt_dlp.YoutubeDL(ydl_opts) as ydl:

        info = ydl.extract_info(url, download=True)

        filename = ydl.prepare_filename(info)


        if filename.endswith(".webm"):

            filename = filename.replace(".webm", ".mp4")

        return filename


@app.route("/", methods=["GET", "POST"])

def index():

    if request.method == "POST":

        url = request.form.get("url")

        format_code = request.form.get("format")

        try:

            file_path = download_video(url, format_code)

            return send_file(file_path, as_attachment=True)

        except Exception as e:

            return f"Error: {str(e)}"

    return render_template("index.html")


if __name__ == "__main__":

    app.run(host="0.0.0.0", port=5000, debug=True)
