  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • rtsp timeout av_read_frame

    30 novembre 2012, par user1175197

    I am using ffmpeg to play an RTSP stream. I have a loop like

        while (av_read_frame(formatContext, packet)>=0)
    
    {
    
      doWork();
    
    }

    I can watch the stream as long as there is something moving in front of the camera. But whenever the view is stable the above function returns EOF as I checked with av_strerror. Any ideas why and how to fix it ?

    thanks

  • ffmpeg settings for high quality youtube videos [migrated]

    1er avril 2018, par pb.

    I am trying to record short video of my desktop and upload it to youtube.
    The problem is that every time when I upload it to youtube or even dropbox (as video), the quality is much worse.

    My ffmpeg execution :

    ffmpeg -f x11grab -s 1366x768 -r 30 -i :0.0 -codec:v libx264 -crf 10 -bf 20 -flags +cgop -pix_fmt yuv440p -movflags faststart help.mp4

    based on :

    ffmpeg -i <input file="file" /> -codec:v libx264 -crf 21 -bf 2 -flags +cgop -pix_fmt yuv420p -codec:a aac -strict -2 -b:a 384k -r:a 48000 -movflags faststart .mp4

    which I found here

    Original file (.zip) :

    File after upload to youtube :

    As you can see, I loss quality after upload to youtube.

    Could you help me ?
    How should I choose the appropriate parameters to record and upload high quality video ?
