  • Anomalie #2024 (Nouveau) : langue des boutons d’admin

    7 avril 2011, par jluc -

    Sur spip.net, depuis plusieurs années, le texte des boutons d’admin m’apparaît en espagnol alors que tous mes paramétrages (espace perso, navigateur etc) sont en français. Je me souviens qu’un habitué d’IRC constatait également ce même (...)

  • How to set min, max and avg bitrate or vbv delay using FFMPEG for livestream in Python ? [closed]

    10 mai, par Tebyy

    I'm trying to set the minimum, maximum, and average bitrate or vbv delay for a WebM livestream in Python using FFMPEG, but it still shows "0" or "N/A". I've checked the documentation, and everything seems correct. I've also searched for solutions online, but none of them have solved my problem. Does anyone know what I might be doing wrong and how it should be done correctly ?

    


    FFMPEG Command :

    


    ffmpeg_command = [
        'ffmpeg', '-f', 'rawvideo', '-pix_fmt', 'bgr24',
        '-s:v', '1920x1080', '-r', '60',
        '-i', '-',
        # '-an',  # Turn off the audio track
        '-c:v', 'libvpx-vp9', '-g', '60', '-keyint_min', '60',
        '-b:v', '6M', '-minrate', '4M', '-maxrate', '12M', '-bufsize', '8M',
        '-crf', '0', '-deadline', 'realtime', '-tune', 'psnr', '-quality', 'good',
        '-tile-columns', '6', '-threads', '16', '-lag-in-frames', '16',
        '-f', 'webm', '-'
    ]
