Puis-je poster des contenus à partir d’une tablette Ipad ?
Oui, si votre Médiaspip installé est à la version 0.2 ou supérieure. Contacter au besoin l’administrateur de votre MédiaSpip pour le savoir
Emballe médias : à quoi cela sert ?

4 février 2011, par kent1

Ce 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" ;
Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

8 février 2011, par kent1

La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

How to add multiple audio to video file at a specific time using ffmpeg

13 mai 2018, par 呂裕翔
I can add one audio to video by using
```
ffmpeg -i input_video -i input_audio -filter_complex "

aevalsrc=0:d=30[s1];

[s1][1:a]concat=n=2:v=0:a=1[aout]" -c:v copy -map 0:v -map [aout] output_video
```
I have no idea how I can add two, three,... audio to video.
I have searched a lot of post, but I can not find the correct answer.
Thank for your help.
FFMPEG - Zoompan image overlay keep ratio

4 mai 2018, par Pier Giorgio Misley
With zoompan I can zoom in and out an image overlayed over a video. My problem is that the image ratio is not respected and the image is stretched in something like 16:9

The image in the center is a phone vertical picture, but It result like this :

Looks like zoompan is trying to stretch to full width and the height to.. something. How can I keep the ratio while zooming ? I tried using sar but it doesn’t work

Note : I read this post and I probably should set the size, but how can I set it to keep the original one ?

Edit :
```
-i "vid.mov" -loop 1 -t 1 -i "1.png" -filter_complex "[1:v]format=rgba,scale=1440x2560,setsar=1/1,zoompan=z='min(zoom+0.0015,1.5)':s=720x1280:d=7250:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)',fade=in:st=20:d=1:alpha=1,fade=out:st=77:d=1:alpha=1[im];[0][im]overlay=(main_w-overlay_w)/2:(main_h - overlay_h)/2:shortest=1" -pix_fmt yuv420p -c:a copy output_0.mp4
```
With this, in some video format/resolutions it works, in others not

ie : with .mp4 it works, with .mov it doesn’t

Edit2 :

here is the log (names here are not truncated, there is the full path instead of file name)
