MediaSPIP : Modification des droits de création d’objets et de publication définitive
11 novembre 2010, parPar défaut, MediaSPIP permet de créer 5 types d’objets.
Toujours par défaut les droits de création et de publication définitive de ces objets sont réservés aux administrateurs, mais ils sont bien entendu configurables par les webmestres.
Ces droits sont ainsi bloqués pour plusieurs raisons : parce que le fait d’autoriser à publier doit être la volonté du webmestre pas de l’ensemble de la plateforme et donc ne pas être un choix par défaut ; parce qu’avoir un compte peut servir à autre choses également, (...) -
Encoding and processing into web-friendly formats
13 avril 2011, parMediaSPIP automatically converts uploaded files to internet-compatible formats.
Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
All uploaded files are stored online in their original format, so you can (...) -
Contribute to translation
13 avril 2011You can help us to improve the language used in the software interface to make MediaSPIP more accessible and user-friendly. You can also translate the interface into any language that allows it to spread to new linguistic communities.
To do this, we use the translation interface of SPIP where the all the language modules of MediaSPIP are available. Just subscribe to the mailing list and request further informantion on translation.
MediaSPIP is currently available in French and English (...)

issue after video rotation how fix
2 avril 2015, par VahagnI have next code for rotate video
OpenCVFrameConverter.ToIplImage converter2 = new OpenCVFrameConverter.ToIplImage() ;
for (int i = firstIndex; i <= lastIndex; i++) {
long t = timestamps[i % timestamps.length] - startTime;
if (t >= 0) {
if (t > recorder.getTimestamp()) {
recorder.setTimestamp(t);
}
Frame g = converter2.convert(rotate(converter2.convertToIplImage(images[i % images.length]),9 0));
recorder.record(g);
}
}images[i] - Frame in JavaCV
after in video have green lines
UPDATE

ffmpeg LGPL Windows x64 compile error
29 août 2013, par Cosmin MarcI'm trying to compile ffmpeg for Windows 7 64bit version with LGPL license.
To configure this, I'm using the following command :
./configure --prefix=ffmpeg/ --enable-shared --extra-cflags=-I/c/MinGW/include --yasmexe='C:/yasm/yasm-1.2.0-win64.exe' --enable-version3 --cpu=i686 --arch=x86_64after executing this command I receive the following error :
gcc is unable to create an executable file. If gcc is a cross-compiler, use the —enable-cross-compile option. Only do this if you know what cross compiling means. C compiler test failed.
If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "config.log" produced by configure as this will help solving the problem.
Cross compiling is not what I want... I just want to compile the ffmpeg on W7 x64 with LGPL license.
