    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.

  • FFmpeg 3.3.4 avfoundation to record only a specific section of the screen on macOS Sierra using the command line

    16 octobre 2017, par antedesk

    I’m using FFmpeg version 3.3.4 (installed via brew) through the command line to record my desktop during some automated tests on my macOS Sierra (10.12.6).

    I would like to record only a specific section of the screen but, unfortunately, I’m not able to find the proper options in the documentation to reach my goal.

    According to the FFmpeg documentation for avfoundation, this is the command I use :

    ffmpeg
    -f avfoundation    // avfoundation
    -pix_fmt uyvy422   // pixel format
    -i 1               // input: desktop
    -r 30              // framerate for output
    [PATH]/test.mp4      // filename

    When I run this command I have the following output :

  • FFMPEG avi to streaming mp4

    29 mai 2013, par Vprnl

    I'm trying to get ffmpeg to encode various AVI files to mp4 for streaming purposes but my inexperience with the subject matter is making me doubt I'll ever get this to work.

    I use this commandline :

    ffmpeg -i test.avi -vcodec libx264 -r 24 -ac 2 -acodec ac3 -ab 128k -bt 240k -preset    fast -strict -2 -b:v 320K -bufsize 62000 -maxrate 62000 -movflags frag_keyframe+empty_moov test.mp4

    I use the " -movflags frag_keyframe+empty_moov" to make it possible to serve a fragmented mp4

    And this is the log I get :

    I hope someone can point me in the right direction. The goal is to serve the file to a html5 player. But sadly that has not yet worked.
    Thanks !

    [EDIT]

    Sorry if I'm being unclear. I have two issues. First FFMPEG gives me an error (as you can see in the log) but I'm uncertain why I get this error and secondly, the stream does not actually work. The tanscoding starts, but the player never receives the video
