Les statuts des instances de mutualisation
13 mars 2010, parPour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...) -

Why pixels color are different before and after encoding ? , How to set the same ?
11 mars 2015, par mitliI want to change some pixels of some frames, I do this steps :
1 - Extract frames from FLV video to PNG
2 - Change frame pixels color ,For example I set color of Pixel(0,0) to ARGB (0,0,0,0)
3 - Encode frames to a video by below code :
-i Frame%04d.png -filter_complex "[0:0] scale= [wm]; [wm][1:0] overlay=1:1 [out]" -map "[out]" -map 0:a -c:v libx264 -vprofile low outfile.flvBut when I check "outfile.flv" frames , pixel 0,0 is 255,7,2,3 instead of 0,0,0,0 , why ? Please tell me that how can I get same pixels color after encode ?

JavaCV generate video from images Crashes
2 décembre 2014, par Mohammad KhatriI am doing javacv with android since yesterday and getting error while generating video from image (IplImage) using FFmpegFrameRecorder or FrameRecorder while getting succes in imagefiltering using cvCvtColor and cvCvtColor.
As shown in picture , Grayscale and flip filter is done by clicking second Button (Apply Effect).
But when clicking (Make Video) it crashes.
Here is my code for making video from image.
String path = Environment.getExternalStorageDirectory().getPath() + "/test.mp4";
Log.i("path", path);
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(path, 256, 256);
try {
recorder.setVideoCodec(avcodec.AV_CODEC_ID_MPEG4);
// recorder.setCodecID(avcodec.AV_CODEC_ID_H263);
recorder.setFormat("mp4");
recorder.setPixelFormat(avutil.AV_PIX_FMT_YUV420P);
recorder.start();
for (int i = 0; i < 10; i++) {
recorder.record(image);
}
recorder.stop();
} catch (Exception e) {
e.printStackTrace();
}image is of type IplImage
getting error on recorder object creation.
I am using 2 devices
1)Asus zenfone 5
