  • 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) (...)

  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • ffmpeg : avi to mp4 (h.264/aac) - sound yes, image no

    21 février 2013, par user1711384

    working with ffmpeg at a conversion (any file to mp4 (h.264/aac)) :

    exec("ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 1 -an -f mp4 -movflags faststart /dev/null && \ ", $output1);
    var_dump($output1);
    exec("ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 2 -c:a libfdk_aac -b:a 128k -movflags faststart xxx.mp4 2>&1", $output2);
    var_dump($output2);

    With a mpeg and wmv-file its working. With 2 differenz AVIs it didnt work, logfiles from path 1 arent generated and output1 is empty, output2 of course generates an error. After removing -profile:v baseline in both commands, the videofile is successfull generates, but its not possible to play it in jwplayer (sound yes, but no image).

    This is the content of output1 :

  • Who can tell me the difference and relation between ffmpeg, libav, and avconv

    25 septembre 2014, par why

    when I run ffmpeg on Ubuntu, it shows :

    $ ffmpeg
    ffmpeg version v0.8, Copyright (c) 2000-2011 the Libav developers
     built on Feb 28 2012 13:27:36 with gcc 4.6.1
    This program is not developed anymore and is only provided for compatibility. Use avconv instead (see Changelog for the list of incompatible changes).

    or it shows (depending on Ubuntu version) :

    $ ffmpeg
    ffmpeg version 0.8.5-6:0.8.5-0ubuntu0.12.10.1, Copyright (c) 2000-2012 the Libav developers
     built on Jan 24 2013 14:49:20 with gcc 4.7.2
    *** THIS PROGRAM IS DEPRECATED ***
    This program is only provided for compatibility and will be removed in a future release. Please use avconv instead.

    I found avconv on http://libav.org, I am just perplexed by them

  • Help us Reset The Net today on June 5th

    5 juin 2014, par Piwik Core Team — Community, Meta

    This blog post explains why the Piwik project is joining ResetTheNet online protest and how you can help make a difference against mass surveillance. It also includes an infographic and links to useful resources which may be of interest to you.

    Snowden revelations, a year ago today

    On June 5, 2013 the Guardian newspaper published the first of Edward Snowden’s astounding revelations. It was the first of a continuous stream of stories that pointed out what we’ve suspected for a long time : that the world’s digital communications are being continuously spied upon by nation states with precious little oversight.

    Unfortunately, mass surveillance is affecting the internet heavily. The Internet is a powerful force that can promote democracy, innovation, and creativity, but it’s being subverted as a tool for government spying. That is why Piwik has decided to join Reset The Net.

    June 5, 2014 marks a new year : a year that will not just be about listening to the inside story of mass surveillance, but a new year of fighting back !

    How do I protect myself and others ?

    Reset the Net is asking everyone to help by installing free software tools that are designed to protect your privacy on a computer or a mobile device.

    Reset the Net is also calling on websites and developers to add surveillance resistant features such as HTTPS and forward secrecy.

    Message from Edward Snowden

    Evan from FFTF sent us this message from Edward Snowden and we thought we would share it with you :

    One year ago, we learned that the internet is under surveillance, and our activities are being monitored to create permanent records of our private lives — no matter how innocent or ordinary those lives might be.

    Today, we can begin the work of effectively shutting down the collection of our online communications, even if the US Congress fails to do the same. That’s why I’m asking you to join me on June 5th for Reset the Net, when people and companies all over the world will come together to implement the technological solutions that can put an end to the mass surveillance programs of any government. This is the beginning of a moment where we the people begin to protect our universal human rights with the laws of nature rather than the laws of nations.

    We have the technology, and adopting encryption is the first effective step that everyone can take to end mass surveillance. That’s why I am excited for Reset the Net — it will mark the moment when we turn political expression into practical action, and protect ourselves on a large scale.

    Join us on June 5th, and don’t ask for your privacy. Take it back.
