  • How easy is it to create a YouTube to MP3 application using yt-dlp and ffmpeg ?

    26 juin 2022, par fowlis

    I was thinking I could automate the process of downloading a video and converting it to mp3 (or other formats).
    
Instead of doing the process myself (which doesn't take that long and isn't too much hassle), which looks something like this :
    
• yt-dlp https://www.youtube.com/watch?v=dQw4w9WgXcQ
    
• wait for download then (find and) rename file to something simpler for next command
    
• ffmpeg -i video.mp4 video.mp3


    


    I thought I could turn it into a simple JS (or other language) program instead, where it :

    


      

    1. Asks for link and what format I want it in

      2. 


    2. Downloads the video

      3. 


    3. Renames it (not sure how easy this is)

      4. 


    4. Turns it into requested format

      5. 


    5. Opens file location

      6. 


    


    If something like this is possible, please let me know some things I should know since I've never written a windows app before, and some general guidance for how I could do this.

    
I apologise if questions like this aren't exactly allowed on this site, its my first time posting too.
    
Thanks in advance !

    


  • FFmpeg metadata tags for YouTube 3D side-by-side movies

    17 février 2021, par Some1Else

    YouTube requires specific metadata tags for 3D Side-By-Side format movies. If the tag is not there then YouTube does not give the anaglyph playback options for the end user.

    



    Their "help" is here
https://support.google.com/youtube/answer/7278886?hl=en-GB

    



    I am trying to get FFmpeg to add the MP4 tag when building my movie.

    



    Code that works now for a series of PNG files into a MP4.

    



    "ffmpeg.exe" -framerate 60 -i "VID%05d.PNG" -c:v libx264 -preset:v veryslow -profile:v high -crf 15 -s 1280x720 -pix_fmt yuvj420p -an -y "OUTPUT.MP4"


    



    But when I add the tag from the YouTube help page

    



    "ffmpeg.exe" -framerate 60 -i "VID%05d.PNG" -c:v libx264 -preset:v veryslow -profile:v high -crf 15 -s 1280x720 -pix_fmt yuvj420p -an -y -x264opts "frame-packing=3:frame-packing-interpret=1:frame-packing-quincunx=0:frame-packing-grid=0,0,0,0" "OUTPUT.MP4"


    



    I get this error from FFmpeg

    



    [libx264 @ 0000000002a8c3a0] bad option 'frame-packing-interpret': '1'


    



    This page (ignore the proselytising)

    



    http://www.pantherdynamics.yolasite.com/panther-dynamics-blog/uploading-3dsbs-content-to-youtube

    



    says you only need to use this tag

    



    -x264opts frame-packing=3


    



    Using that does make FFmpeg finish correctly, but the SBS is still ignored by YouTube

    



    The YouTube engineer blog post here

    



    https://youtube-eng.googleblog.com/2011/09/getting-3d-content-on-youtube_8.html

    



    links to an older supposed 3D movie that also does not give 3D options any more.

    



    https://www.youtube.com/watch?v=ubRHSg5daMs

    



    So maybe even YouTube's own 3D movies are crippled ?

    



    What am I doing wrong ? Any FFmpeg gurus able to help ?
