  • Les tâches Cron régulières de la ferme

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.

  • How to install ffmpeg

    8 octobre 2017, par user5913892

    I want to make a "mini" editor video. My goal is, cut some part of the video and then save it and also create an undo button. Now , I was looking for the best solution (This operation have to be done in a website) and I found that I have to use ffmpeg.

    So, I have not ffmpeg installed on that server. The server should be Linux, I say this because I use one of the many website in Internet to discover it.
    enter image description here

    I know that the website say that the Webserver is Engine-x, but my company has told that is Apache (as the php script already told me). Now , I found this link http://www.mysql-apache-php.com/ffmpeg-install.htm (in Stackoverflow and many other parts) that say how to install ffmpeg in Linux, but Where should I execute these commands ? Should I use Putty ? or What ?

  • Unable to 'make' android ndk project - build fails : [build-openh264-x86] Error 2

    18 décembre 2015, par NoobNinja

    I’ve attempted these two fixes I’ve found while researching the issue :

    android update project  --23 --/Users/ajswann/Downloads/android-sdk-macosx 
    

    
make OS=android NDKROOT=/Users/ajswann/Downloads/android-sdk-macosx TARGET=android-19 ARCH=x86 clean

    ...however neither seems to resolve the issue.

    Any input/suggestions are appreciated.

    P.S.

    I’m running OSX - could this be an issue with attempting to run an x86 architecture on a 64 bit machine ?
