  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Prevent output in error log when ffmpeg job is initiated via PHP's shell_exec()

    19 janvier 2016, par Jake

    I’m getting the entire output of the ffmpeg command printed to my server’s error.log — but as far as I can tell, the jobs complete successfully with no error.

    Is there any way to suppress the output ? I have seen people append stuff like >/dev/null 2>/dev/null & to their command, however that forces the command to return immediately and the job runs in the background. Unfortunately, I need the job to run in the foreground, because I need to do stuff with the output once the job is done.

    Here’s the command I am running...

    shell_exec('ffmpeg -i input.mp4 -f mp4 -c:v libx264 -preset slow -crf 24 -s 1280x720 -c:a libfdk_aac -profile:a aac_he -ar 22050 -b:a 64k -movflags +faststart output-1280x720.mp4');

    Here’s the output I am seeing...

  • ffmpeg android unable to build

    2 janvier 2014, par nmxprime

    My goal is to build ffmpeg static libraries so that i can use them with jni and call directly the functions defined in ffmpeg to encode series of images as h264 video stream and render it on screen using GLSurfaceVIew in android 2.3.6.

    Using https://www.ffmpeg.org/doxygen/0.6/api-example_8c-source.html i came to know that by having the required .so files and headers i can do that.

    I followed Android NDK & FFMPEG build and many others. Everywhere i found reference to the build scripts by roman10.

    I use Ubunthu 12.0.4 LTS with android-ndk-r9 and ffmpeg-0.10 source !
