  • Python - youtube-dl.utils.DownloadError : ERROR : audio conversion failed : file : mp3 invalid argument

    14 mars 2017, par Cristina

    youtube-dl.utils.DownloadError: ERROR: audio conversion failed: file: mp3 invalid argument

    The above error appears with following parameters, running youtube-dl on Python 3.6 on Windows 7, FFmpeg and libmp3lame installed.

    ydl_opts = {                                                
    
"format": "bestaudio/best",
    
"extractaudio": True,

    "preferredquality": "192",
    
}],
    
"progress_hooks": [hook]
    
}

    fetch_name is for example C:\Path\File. [hook] just displays download messages.
    I’ve searched here and on internet but can’t find this error.

  • Stream is not appearing on youtube

    1er novembre 2022, par AMRITESH GUPTA

    I am trying to stream a captured stream to youtube live through FFmpeg, but the stream is not appearing on youtube. I tried giving input from an mp4 file, and it worked perfectly but providing input as a buffer through stdin gives nothing.

    


    FFmpeg command

    


    ffmpeg -rtbufsize 100M -report -i - -v error -c:v libx264 -preset veryfast -tune zerolatency -g:v 60 -c:a aac -strict -2 -ar 44100 -b:a 64k -y -use_wallclock_as_timestamps 1 -async 1 -f flv ${youtubeURL}

    


    I used -report for generating a log report, and I couldn't find anything wrong with it.

    


    Here is snippet of log file
