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 (...) -
HTML5 audio and video support
13 avril 2011, parMediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
For older browsers the Flowplayer flash fallback is used.
MediaSPIP allows for media playback on major mobile platforms with the above (...) -
Support audio et vidéo HTML5
10 avril 2011MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.

Recording video on Android using JavaCV
11 décembre 2013, par Fabio BergmannI'm trying to record a video in Android using the JavaCV lib.
I need to record the video in 640x360.I have installed everything as described in README.txt file and I followed the example as below :
https://code.google.com/p/javacv/source/browse/samples/RecordActivity.java
In this example, the video size is this :
private int imageWidth = 320 ;
private int imageHeight = 240 ;In my case, I need to record a video in 640x360 H.264.
But, or I get an exception or the video records with no correct image.I think that the fix is arround a correct combination on :
yuvIplimage = IplImage.create(imageWidth, imageHeight, IPL_DEPTH_8S, 2) ;
changing the depth and :
recorder.record(yuvIplimage, AV_PIX_FMT_VDPAU_H264) ;
the pixel format.Here is my code :

Recording video on Android using JavaCV (Updated)

In this example, the video size is this :
private int imageWidth = 320 ;
private int imageHeight = 240 ;In my case, I need to record a video in 640x360 H.264.
(UPDATE) I have reverted my code and kept exactly like in the example, just changing imageWidth and imageHeight to 640x360.

3 janvier 2014, par NikitaI am able to create the m3u8 file by following steps :
1.Execute ffmpeg -v verbose -i rtmp://<host>:<port>/<stream> -c:v libx264 -c:a aac -ac 1 -strict -2 -crf 18 -profile:v baseline -maxrate 400k -bufsize 1835k -pix_fmt yuv420p -flags -global_header -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 <pathtofolderyouwantto>/<streamname>.m3u8
</streamname></pathtofolderyouwantto></stream></port></host>2.Make that folder you just mentioned on ffmpeg command () to be accessible by an http url.
3.Create a simple html page to play :
<video controls="controls" width="480" height="270" src="<streamName>.m3u8"></video>
But not able to play using html5 video tag as well as in apple device.
following is my ffmpeg console output :
