Amélioration de la version de base
13 septembre 2013Jolie sélection multiple
Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...) -
Menus personnalisés
14 novembre 2010, parMediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
Menus créés à l’initialisation du site
Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...) -
Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

How to get stream info from opened file in ffmpeg ?
31 mai 2013, par Srv19I am trying to read video file using ffmpeg. I had working code that corresponded to somewhat old version of it, and started to try and upgrade to latest build version, exchanging all those deprecated functions for their actual analogues.
However i have run into a problem. No streams seem to be retrieved and the load of video stops dead in tracks.
here is the code i am using :
// Open video file
if(avformat_open_input(&pFormatCtx, filename.toStdString().c_str(), NULL, NULL)!=0)
return FILE_NOT_OPENED; // Couldn't open file
// Retrieve stream information
if(avformat_find_stream_info(pFormatCtx,NULL)<0)
return NO_STREAM_INFO; // Couldn't find stream information
// Dump information about file onto standard error
av_dump_format(pFormatCtx, 0, filename.toStdString().c_str(), false);
// Find the first video stream
videoStream=-1;
for(unsigned i=0; inb_streams; i++)
if(pFormatCtx->streams[i]->codec->codec_type==ffmpeg::AVMEDIA_TYPE_VIDEO)
{
videoStream=i;
break;
}
if(videoStream==-1)
return OTHER; // Didn't find a video stream
// Get a pointer to the codec context for the video stream
pCodecCtx=pFormatCtx->streams[videoStream]->codec;
// Find the decoder for the video stream
pCodec=avcodec_find_decoder(pCodecCtx->codec_id);
if(pCodec==NULL)
return CODEC_NOT_FOUND; // Codec not found
// Open codec
if(avcodec_open2(pCodecCtx, pCodec,NULL)<0)
return CODEC_NOT_OPENED; // Could not open codecThe problem arises in the cycle through video streams in
ffmpeg::AVFormatContext *pFormatCtx
. nb_streams field is 0, and i never actually enter the cycle, and codec is not loaded etc. Strange thing is, av_dump_format gives following output :License: GPL version 3 or later

python ff-mpeg not working on VM
2 août 2013, par BobI have two Windows 2008 R2 64 bit servers with two different host providers (GoDaddy and company B). My python script runs successfully on GoDaddy's server. It doesn't run successfully on the server with company B.
I installed the same software on both servers :
- Python 2.7 for Windows 32 bit
- NumPY module
- SetupTools
- EchoNest API for Windows
The company B server is giving me an error related to an executable called en-ffmpeg.exe that uses the python ff-mpeg module. The exact error message is
[dv @ 0x1449690]Can't determine profile of DV input stream.
C :\Music\song1.mp3 : Error while opening fileThe song.mp3 file exists. I installed the latest Windows updates on the server with Company B but still I get the error. I believe the error is because something is not configured properly on this server (missing libraries or drivers ?). However, I don't know what that is !
Please help :)
