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 loop ffmpeg in script [duplicate]
6 mai 2020, par serge lesnichyGood afternoon !

There is a list of clips that I need to download partially, indicating the beginning (second column) and end (third column) and the name under which it is saved (fourth column).


url1 00:14:00 00:15:00 name1
url2 00:09:00 00:10:10 name2
url3 00:14:00 00:15:00 name3
url4 00:09:00 00:10:20 name4


and there is a script with which i need to download this clips.



#!/bin/bash
 cat ./list | while read line; do
 url=$(echo $line | awk '{print $1}');
 start=$(echo $line | awk '{print $2}');
 end=$(echo $line | awk '{print $3}');
 name=$(echo $line | awk '{print $4}');
 clip=$(echo "ffmpeg -ss "$start" -to "$end" -i "\$\(youtube-dl -g \"$url\"\)" -c copy ./"\""$name"\"".mp4");
 bash -c "$clip"
 done;


After starting, only the first clip is downloaded and the cycle ends.

How to continue script execution ?

Tell me where I messed up ?

Thank !

Error transcoding with FFmpeg : Error : Output format hls is not available
6 mai 2024, par asif mohmdI am using FFmpeg library to transcode a video file into multiple resolutions and create an HLS (HTTP Live Streaming) master playlist.


It takes a video file as input but its does give me the output with HLS playlist.I got a error called "Output format hls is not available". Only the Output directory is creating


I am using FFMpeg 7.0 full build version and also tried older versions and ffmpeg essentials and also tried chocolatey.


if i remove the implementation of HLS from this code.it will create 4 different resolution videos in my output.


Note:I just tried this same code on my friend MAC Book by only changing the setffmpegPath : "ffmpeg.setFfmpegPath("C :\ffmpeg\bin\ffmpeg.exe") ;" to his ffmpeg directory.
Its working perfectly in his mac book


import "dotenv/config";
import * as fs from "fs";

Creating Thumbnails From Ffmpeg Hangs Php
30 octobre 2012, par Piyush AroraI have been working on a php webservice, which receives videos(uploaded) from iphone and upload them to Amazon cloudFront. After uploading videos, I need to generate thumbnails for video from the Amazon link generated. I am using ffmpeg with
shell_execcommand for it. Here is the code for the same :public function createThumbnail($userId,$fileUrl,$imageName){
//$imageUrl = 'http://184.168.116.177:81/json_api/json/bin/';
if(!is_dir("images/".$userId)){
mkdir("images/".$userId);
}
// path of installed ffmpeg
$ffmpeg = $_SERVER['DOCUMENT_ROOT'] .'bin/ffmpeg';
$cmd = "$ffmpeg -itsoffset -1 -i $fileUrl -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 images/".$userId."/".$imageName;
shell_exec($cmd);
return "images/".$userId."/".$imageName;
}The above code generates the thumbnail, but script does not execute after shell_exec command. So, there is no response sent to iphone end about the thumbnail link. This function works well video is uploaded from web browser of pc. If I comment, shell_exec command, then response is sent to iphone end, but obviousely image is not created.
Thanks in advance.
