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 ; (...) -
Le plugin : Gestion de la mutualisation
2 mars 2010, parLe plugin de Gestion de mutualisation permet de gérer les différents canaux de mediaspip depuis un site maître. Il a pour but de fournir une solution pure SPIP afin de remplacer cette ancienne solution.
Installation basique
On installe les fichiers de SPIP sur le serveur.
On ajoute ensuite le plugin "mutualisation" à la racine du site comme décrit ici.
On customise le fichier mes_options.php central comme on le souhaite. Voilà pour l’exemple celui de la plateforme mediaspip.net :

FFMpeg or other how to add dynamic text into video stream
17 février 2017, par FergusonI’am looking for a solution on how to add some dynamic text into the video stream. For example I have a underwater webcam (IP cam) and now I want to add information about measured temperature and salinity into video stream (as text). The final result must be a video stream with temp and salinity displayed in video.
For this project I’am using OrangePI pc with Armbian OS.
Can it be done with FFMpeg or is there some other option ?Regards

Flutter : How to use "ffmpeg_kit_flutter" to merge videos ?
28 mai 2024, par Hani Kanakrii am using "ffmpeg_kit_flutter" to merge two videos with code

In "mergeVideos" function the "returnCode" it return value "1" when i look in the package code


getState() async {
 try {
 return _platform
 .abstractSessionGetState(this.getSessionId())
 .then((state) {
 switch (state) {
 case 0:
 return SessionState.created;
 case 1:
 return SessionState.running;
 case 2:
 return SessionState.failed;
 case 3:
 default:
 return SessionState.completed;
 }
 });
 } on PlatformException catch (e, stack) {
 print("Plugin getState error: ${e.message}");
 return Future.error("getState failed.", stack);
 }
}


Which mean its keep running but in my code it does not wait until complete merging


how can i fix that ??!


but i think my problem is in command(concat)



-i /storage/emulated/0/Movies/VID_20240512_115128.mp4 -i /storage/emulated/0/Movies/VID_20240512_115116.mp4 -filter_complex "[0:v][1:v]concat=n=2:v=1:a=0[outv]" -map "[outv]" -y /storage/emulated/0/merged_video_2024513_122719.mp4


(This is my command when i run the code) ??
