Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

Recording a webpage stream with multiple requests using PhantomJS & ffmpeg to /dev/stdout leads to ffmpeg error
2 septembre 2016, par Allisson FerreiraFirst of all, sorry for my english.
I’m in a quest for days. I’ve researched everywhere and I couldn’t find an answer to my problem.
I’m using Nodejs, Phantomjs and ffmpeg in this scenary :
- An user enters the site, login with facebook and he can ask for a video with his name and some random photos (gathered by /me/ & sent via JSON POST) ;
- Node receive the user data, creates a child process (PhantomJS + ffmpeg) and awaits for a response to send the video URL to the user.
When I run a single instance of this request, everything is working fine. BUT, when two or more users make the request, only one video is sent and the others process end up in a ffmpeg stream error.
I think the reason is that all the ffmpeg processes are using the same place (/dev/stdout). Since one process is already using it, the others enters in a "can’t access" error. But it is a assumption, I don’t know how /dev/stdout really works.
Here are my codes. (I have removed some lines and renamed some variables for better understanding, sorry for any mistake)
index.js :
var generateVideo = 'phantomjs phantom.js '+videoID+' '+userID+' | ffmpeg -vcodec png -f image2pipe -r 30 -i - -pix_fmt yuv420p public/videos/'+userID+'/'+videoID+'.mp4 -y';
childProcess.exec(generateVideo, function(err, stdout, stderr) {
var json = {};
json.video = '/videos/'+userID+'/'+videoID+'.mp4';
res.send(json);
});phantom.js :
var page = require('webpage').create();
page.viewportSize = { width: 1366, height: 768 };
page.settings.resourceTimeout = 10000;
var args = require('system').args;
var videoID = args[1];
var userID = args[2];
page.open('http://localhost:3000/recordvideo/'+videoID, 'post', function(status){
var frame = 0;
var target_fps = 30;
var maxframes = page.evaluate(function () {
return getTotalDurationInSeconds();
}) * target_fps;
setInterval(function(){
page.render('/dev/stdout', { format: "png" });
if( frame >= maxframes ){
phantom.exit();
}
frame++;
}, (1000 / target_fps));
});And the error :
[Error: Command failed: /bin/sh -c phantomjs phantom.js XXXXXXXX XXXXXXXX | ffmpeg -vcodec png -f image2pipe -r 30 -i - -pix_fmt yuv420p public/videos/XXXXXXXX/XXXXXXXX.mp4 -y

ffmpeg concat video fails on Android
2 septembre 2016, par CynapsisI’m using this library to integrate ffmpeg to my android app.
I was able to successfully crop videos with the library but now I need to concatenate two videos that are exactly the same resolution.
The ffmpeg command I use is
-i input1.mp4 -i input2.mp4 -filter_complex concat=n=2:v=1:a=1 -f MP4 out.mp4I’m getting the above error when I run that command on those 2 videos

What did I miss ? What does this error mean ?
