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 (...) -
Emballe médias : à quoi cela sert ?
4 février 2011, parCe plugin vise à gérer des sites de mise en ligne de documents de tous types.
Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ; -
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 ; (...)

Module not found : Can't resolve './lib-cov/fluent-ffmpeg'
29 mars 2021, par anInputNameI created this project using
npx create-react-app, and I'm trying to useffmpeg-concat, but I get the error in the title. Node versionv14.15.1, npm version7.7.5. I haveffmpeginstalled and in my PATH.

Error :


./node_modules/fluent-ffmpeg/index.js
Module not found: Can't resolve './lib-cov/fluent-ffmpeg' in 'C:\Users\XXX\Desktop\test\node_modules\fluent-ffmpeg'


My code :


function App() {
 //this is taken from ffmpeg-concat documentation page
 const concat = require('ffmpeg-concat')
 await concat({
 output: 'test.mp4',
 videos: ["videos/a.mp4", "videos/b.mp4", "videos/c.mp4"],
 transition: {
 name: 'directionalWipe',
 duration: 500
 }
 })

 return (
 <div classname="App">
 <header classname="App-header">
 <video input="{"test.mp4"}"></video>
 </header>
 </div>
 );
}

class Video extends Component {
 render() {
 return (

"Could not demultiplex stream" in loading Video recorded by Opencv's VideoWriter
21 novembre 2020, par batumanMy program is



int main(){
 cout << "Start the process" << endl;
 cv::VideoCapture vcap("rtsp://root:pass@192.168.0.90/axis-media/media.amp?camera=1");
 cout << "Camera connection done!" << endl;
 cv::Mat image, small;
 //Output video
 cv::Size S = cv::Size((int) vcap.get(CV_CAP_PROP_FRAME_WIDTH), (int) vcap.get(CV_CAP_PROP_FRAME_HEIGHT));
 int ex = static_cast<int>(vcap.get(CV_CAP_PROP_FOURCC));
 int fps = vcap.get(CV_CAP_PROP_FPS);
 cout << "fps " << fps << " ex " << ex << endl;
 cv::VideoWriter outputVideo;
 outputVideo.open("TEST.avi", ex/*CV_FOURCC('X', '2', '6', '4')*/, vcap.get(CV_CAP_PROP_FPS), S, true);
 if(!outputVideo.isOpened()){
 cout << "Could not open the output video for write" << endl;
 return -1;
 }

 for(;;){
 if(!vcap.read(image)){
 std::cout << "No frame" << std::endl;
 cv::waitKey(0);
 }

 cv::resize(image, small, image.size()/2, 0, 0 , cv::INTER_LINEAR);
 cv::imshow("Display", small);
 cv::waitKey(1);
 outputVideo.write(small);
 if(getkey() == '\n')
 break;
 }
 cout << "Camera release" << endl;
 outputVideo.release();
 vcap.release();
 image.release();
 small.release();
 return 0;
}
</int>


int ex = static_cast<int>(vcap.get(CV_CAP_PROP_FOURCC));</int>ex is 0 here.


I can record the TEST.avi, but can't be read by cv::VideoCapture vcap("TEST.avi") ; or VLC player or Videos in Ubuntu.
The error is
"Could not demultiplex stream".


If I changed to



outputVideo.open("TEST.avi", CV_FOURCC('X', '2', '6', '4'), vcap.get(CV_CAP_PROP_FPS), S, true);
outputVideo.open("TEST.avi", CV_FOURCC('P','I','M','1'), vcap.get(CV_CAP_PROP_FPS), S, true);
outputVideo.open("TEST.avi", CV_FOURCC('M', 'P', '4', '2'), vcap.get(CV_CAP_PROP_FPS), S, true);
etc.



all have same problem.



If I set



outputVideo.open("TEST.avi", CV_FOURCC('i', 'Y', 'U', 'V'), vcap.get(CV_CAP_PROP_FPS), S, true);



I have error as
Opencv: FFMPEG iYUV is not supported with codec id 14


For



outputVideo.open("TEST.avi", CV_FOURCC('M', 'J', 'P', 'G'), vcap.get(CV_CAP_PROP_FPS), S, true);


OpenCV Error: Assertion failed (img.cols == width && img.rows == height && chann

der.cpp:829: error: (-215) img.cols == width && img.rows == height && channels =

What could be wrong ? Is that my FFMPEG has problem ?
