Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -
Support de tous types de médias
10 avril 2011Contrairement 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) (...)

Trying to compile x264 and ffmpeg for iPhone - "missing required architecture arm in file"
11 février 2013, par jtrimI'm trying to compile x264 for use in an iPhone application. I see there are instructions on how to compile ffmpeg for use on the platform here : http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-October/076618.html , but I can't seem to find anything this complete for compiling x264 on the iPhone. I've found this source tree : http://gitorious.org/x264-arm that seems to have support for the ARM platform.
Here is my config line :
./configure —cross-prefix=/usr/bin/ —host=arm-apple-darwin10 —extra-cflags="-B /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/ -I /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/"
...and inside
configure
I'm using the gas-preprocessor script (first link above) as my assembler :gas-preprocessor.pl gcc
When I start compiling, it chunks away for a little while, then it spits out these warnings and a huge list of undefined symbols :
ld : warning : option -s is obsolete and being ignored ld : warning : -force_cpusubtype_ALL will become unsupported for ARM architectures ld : warning : in /usr/lib/crt1.o, missing required architecture arm in file ld : warning : in /usr/X11R6/lib/libX11.dylib, missing required architecture arm in file ld : warning : in /usr/lib/libm.dylib, missing required architecture arm in file ld : warning : in /usr/lib/libpthread.dylib, missing required architecture arm in file ld : warning : in /usr/lib/libgcc_s.1.dylib, missing required architecture arm in file ld : warning : in /usr/lib/libSystem.dylib, missing required architecture arm in file Undefined symbols :
My guess would be that the problem has to do with the "missing required architecture arm in file" warning...any ideas ?
