[Python] Getting Error while trying to download youtube video by using python

Code


I'm working on a script that allows users to manually select and download separate video and audio streams from YouTube using yt-dlp. The script lists the available video and audio formats, lets the user choose their desired formats, and then merges them using FFmpeg.

Here’s the complete code:

import yt_dlp
import os
import subprocess

# Function to list and allow manual selection of video and audio formats
def download_and_merge_video_audio_with_selection(url, download_path):
try:
# Ensure the download path exists
if not os.path.exists(download_path):
os.makedirs(download_path)

# Get available formats from yt-dlp
ydl_opts = {'listformats': True}

with yt_dlp.YoutubeDL(ydl_opts) as ydl:
info_dict = ydl.extract_info(url, download=False)
formats = info_dict.get('formats', [])

# List available video formats (video only)
print("\nAvailable video formats:")
video_formats = [f for f in formats if f.get('vcodec') != 'none' and f.get('acodec') == 'none']
for idx, f in enumerate(video_formats):
resolution = f.get('height', 'unknown')
filesize = f.get('filesize', 'unknown')
print(f"{idx}: Format code: {f['format_id']}, Resolution: {resolution}p, Size: {filesize} bytes")

# Let user select the desired video format
video_idx = int(input("\nEnter the number corresponding to the video format you want to download: "))
video_format_code = video_formats[video_idx]['format_id']

# List available audio formats (audio only)
print("\nAvailable audio formats:")
audio_formats = [f for f in formats if f.get('acodec') != 'none' and f.get('vcodec') == 'none']
for idx, f in enumerate(audio_formats):
abr = f.get('abr', 'unknown') # Audio bitrate
filesize = f.get('filesize', 'unknown')
print(f"{idx}: Format code: {f['format_id']}, Audio Bitrate: {abr} kbps, Size: {filesize} bytes")

# Let user select the desired audio format
audio_idx = int(input("\nEnter the number corresponding to the audio format you want to download: "))
audio_format_code = audio_formats[audio_idx]['format_id']

# Video download options (based on user choice)
video_opts = {
'format': video_format_code, # Download user-selected video format
'outtmpl': os.path.join(download_path, 'video.%(ext)s'), # Save video as video.mp4
}

# Audio download options (based on user choice)
audio_opts = {
'format': audio_format_code, # Download user-selected audio format
'outtmpl': os.path.join(download_path, 'audio.%(ext)s'), # Save audio as audio.m4a
}

# Download the selected video format
print("\nDownloading selected video format...")
