• Getting Error while trying to download youtube video by using python

  23 octobre 2024, par Aditya Kumar

  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...")
        with yt_dlp.YoutubeDL(video_opts) as ydl_video:
            ydl_video.download([url])

        # Download the selected audio format
        print("\nDownloading selected audio format...")
        with yt_dlp.YoutubeDL(audio_opts) as ydl_audio:
            ydl_audio.download([url])

        # Paths to the downloaded video and audio files
        video_file = os.path.join(download_path, 'video.webm')  # Assuming best video will be .mp4
        audio_file = os.path.join(download_path, 'audio.m4a')  # Assuming best audio will be .m4a
        output_file = os.path.join(download_path, 'final_output.mp4')  # Final merged file

        # FFmpeg command to merge audio and video
        ffmpeg_cmd = [
            'ffmpeg', '-i', video_file, '-i', audio_file, '-c', 'copy', output_file
        ]

        # Run FFmpeg to merge audio and video
        print("\nMerging video and audio...")
        subprocess.run(ffmpeg_cmd, check=True)

        print(f"\nDownload and merging complete! Output file: {output_file}")

    except Exception as e:
        print(f"An error occurred: {e}")

# Example usage
video_url = "https://www.youtube.com/watch?v=SOwk8FhfEZY"  # Replace with your desired video URL
download_path = 'C:/Users/vinod/Downloads/VideoDownload'  # Replace with your desired download path
download_and_merge_video_audio_with_selection(video_url, download_path)



  


  Explanation :

  


  The script first lists all available video formats (video-only) and audio formats (audio-only) from a given YouTube URL.

  


  It allows the user to manually select their preferred video and audio formats.

  


  After downloading the selected formats, it merges the video and audio streams into a single file using FFmpeg.

  


  Error

  


  while trying to run above mentioned code , I am getting this error :

  


  Merging video and audio...
An error occurred: [WinError 2] The system cannot find the file specified


  


  Requirements :

  


  


  yt-dlp : pip install yt-dlp

  


  


  


  FFmpeg : Make sure you have FFmpeg installed and added to your system's PATH.

  


  


• How do I download the image with metadata in Python ? [closed]

  19 octobre 2024, par Temp Account

  I am downloading some images in Python from the Airtable API and am trying to make a slideshow with them using ffmpeg. I download the images :

  


  urllib2.urlretrieve(img['url'], "output/images/image_"+str(i)+".jpeg")


  


  However, when I run the following ffmpeg command

  


  ffmpeg -framerate 4/60 -i output/images/image_%d.jpeg output/out.mp4


  


  I get the following error :

  However, downloading the images in Chrome then creating the slideshow is successful. The images from Chrome have metadata of the filetype (JPEG), width and height. The images downloaded with Python have no metadata. How do I download that information so that my ffmpeg command will succeed ?

  


  Thanks !

  


• how to download m3u8 with ffmpeg ? [hls prompts : Unable to open key file skd:xxxxxxx] [closed]

  18 octobre 2024, par Mam Ghagh

  There is a m3u8 manifest like :

  


  #EXTM3U
#EXT-X-VERSION:5
#EXT-X-TARGETDURATION:7
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-KEY:METHOD=SAMPLE-AES,URI="skd://xxxxxx",IV=0xXXXXXX,KEYFORMAT="com.apple.streamingkeydelivery",KEYFORMATVERSIONS="1"
#EXTINF:6,
https://someurl.com/index_1_0.ts
#EXTINF:6,
https://someurl.com/index_2_0.ts
...


  


  which is available on https://someurl.com/my.m3u8
  
So, When I executed ffmpeg command
  
ffmpeg -i "https://someurl.com/my.m3u8" -c copy out.mp4
  
the following message appeared
  
[hls @ 000002de75f89bc0] Unable to open key file skd://xxxxxx
  
Now the question is, What is the key and How should I address it ?
