    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • Sync Multiple Video sources based on audio

    14 octobre 2016, par linuxer

    I have 6 videos from 6 separate cameras that I need to sync up. They don’t all start at the same time, and so I am thinking the best route would be based on audio. Is there a way to do this with ffmpeg, or is there a library for C# that I can use ?

    The result needs to be that the 6 videos are synced based on audio, and then trimmed so they are all the same length and audio matches up.

    I am really hoping there are some tools to simplify this, but in my searching I haven’t seen anything.

  • Zoom effect based on audio levels using ffmpeg

    31 juillet 2021, par FOLLGAD

    I'm trying to create a zoom-in/shake effect based on how loud the audio stream's bass is.

    


    I've realized you can use showcqt to get a graph of the sound, but I can't figure out how to pipe that to some zoom function to do zoom based on that.

    


    Any ideas ?

    


  • glreadpixels is slower than x11 based screenshot

    23 décembre 2013, par quartz

    I am working on an opengl based simulation application, in which I need to make multiple screenshots in a second. I have tried 2 ways of doing it in my application.
    1) use glreadpixels
    2) use x11 based screenshot. ex : ffmpeg -f x11grab -s 1024x768 -i :0.0 output.png

    I found that second solution is about 3 times faster than first one. I have expected the first solution to be faster. But in practice it is slower. I am curious why glreadpixels is slower ?
