  • Converting avi to mp4 ffmpeg

    26 octobre 2013, par Dirk Swarz

    I use php code :

    $ffmpeg_command ="ffmpeg -i ".$new_name." -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 ".$anew_name;

    $convert_avi = true ;

    i know that the problem is in here :

    -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5

    Idea is when video is converted i can watch it via flash player and now flash player is saying that video is not found or bad syntax so obviuos its bad syntax but i dont know how to fix it

  • Python yt-dlp and ffmpeg error "merging of multiple formats but ffmpeg is not installed"

    27 mai, par T Tea Tie

    I am using the latest version of yt-dlp with Python 3.9.

    


    I am trying to download a youtube video in mp4 format with outputname as the youtubeid.mp4 and with best resolution not more than 4K.

    


    This is my Python code :

    


    ytid = '4cDqaLxrt6Q'
url = 'https://www.youtube.com/watch?v='+ytid
output_filename = ytid+".mp4"
    
with YoutubeDL({'format': 'bestvideo[height<=?4K]+bestaudio/best', 'output': output_filename}) as ydl:
    ydl.download(url)`#TODO debug FFmpeg and check if outputname is ok


    


    I expected to have an .mp4 file in my current working directory.

    


    Then I installed the latest version of FFmpeg from ffmpeg-master-latest-win64-gpl.zip and put ffmpeg.exe, ffplay.exe and ffprobe.exe in Scripts python folder (where yt-dlp.exe is). I also installed ffmpeg using pip install.

    


    The Traceback is :
