  • 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.

  • Need explanation of details of ffmpeg and pipes comand

    6 décembre 2011, par Don Nummer Jr

    Got the following from FFmpeg FAQ :

    mkfifo intermediate1.mpg
    
mkfifo intermediate2.mpg
    
ffmpeg -i input1.avi -sameq -y intermediate1.mpg < /dev/null &
    
ffmpeg -i input2.avi -sameq -y intermediate2.mpg < /dev/null &
    
cat intermediate1.mpg intermediate2.mpg |\
    
ffmpeg -f mpeg -i - -sameq -vcodec mpeg4 -acodec libmp3lame output.avi

    Before i use or modify it I would like to understand it completely.

    What does the < /dev/null & do ?

    I understand | is pipe but why |\ ?

    What is the -f mpeg after ffmpeg (Seems, it tells ffmpeg to accept the piped in output from the cat(?) )

  • ffmpeg scale2ref explanation ?

    11 décembre 2020, par Geuis

    I'm applying a watermark to a video. I'm trying to get the watermark to scale proportionally to the video dimensions. I've seen maybe a dozen different answers using scale2ref, but no explanations as to actually what's happening, so I'm finding it difficult to know how to implement/make changes to the configs to work for my situation.

    



    Current overlay command :

    



    ffmpeg -i test.mp4 -i logo.png -filter_complex "overlay=0:0" output.mp4


    



    Some answers I've looked at :

    



    ffmpeg creating gif from images, add watermark during creation ?

    



    ffmpeg fix watermark size or percentage

    



    What are the rules to how scale2ref works ?

    


  • Free video file converter for c#

    29 novembre 2011, par Richard77

    I'm looking for a library in C#(not commandline) that converts video files' from one format to another.

    While googling, I've seen that many people have asked this question before. Unfortunately those questions were asked years in the past. The most recent of them was aked in april of 2010.

    I've read a lot about FFMPEG, but I don't see any tutorial on how to use that library in C#.

    Please, help with sample codes if possible.

    Thanks for helping
