  • Downloading individual songs from YouTube playlist [closed]

    23 août 2024, par user26961371
      

    • I've created a custom script using yt-dlp.

      • 


    • The script takes a single argument, which is the actual playlist URL.

      • 


    • I'm using the following command :

      • 


    


    yt-dlp --extract-audio --audio-format mp3 --yes-playlist -o "/Users/$USER/Desktop/%(id)s.%(ext)s" --embed-chapters $1


    


    Try :
I've run the command with a valid playlist URL, but it's downloading each song from the playlist into a single MP3 file for each song. I want to download each song as an individual file, not the entire playlist in a single file 15 times.

    


    Expectation :
I expect yt-dlp to download each song from the playlist as a separate MP3 file, rather than combining all songs into a single MP3 file for each song.

    


    Context :
The issue is likely due to the use of the --yes-playlist option, which tells yt-dlp to treat the input as a playlist URL and download all songs in one go.
I've checked the official documentation for yt-dlp, but I couldn't find a solution.

    


  • webm to mp4 without loosing audio video sync

    9 avril 2018, par Kishore

    Iam trying to covert webm to mp4 using ffmpeg so that the output file is playable in all browsers.

    Iam using this ffmpeg command in ubuntu

    ffmpeg -i inpput.webm -f mp4 -copyts -vcodec libx264 -strict -2 -vf scale="380:-2" -pix_fmt yuv420p -profile:v baseline -level 3 output.mp4

    It is converting the file to mp4 but that file is out of sync in Mac safari browser and chrome browser. Means the audio and video is not syncing and sometimes the video gets stopped in between and audio goes on.

    If I play the input.web media file directly in chrome it is playing perfectly fine, the same input.webm is also playing good with firefox. But the converted mp4 is out of sync in safari on mac and all chrome browsers.

    However if the output.mp4 is played on ipad safari it is playing fine.
    The Mac safari version I tried is 11.03
    iPad safari version is 11.3

    Firefox and chrome are all latest.

    firefox : 59.0.2(64 bit),
    chrome : 65.0.3325.181 (Official Build) (64-bit)

    Please help me out with what Iam doing wrong.

    Thanks in advance.
