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. -
Supporting all media types
13 avril 2011, parUnlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

Issue in CV_FOURCC('H', '2', '6', '4')
16 décembre 2014, par AshwinI am trying to use H264 encoding type for compressing the live streaming from Camera (which is supporting the H264 codec) am getting below -
[I am using OPENCV 3.0 beta version (latest)in windows 7 64 bit system .My camera is also supporting H264 codec (find more details below) ]
My ffmpeg code got built with h264 lib :
This build was compiled with the following external libraries :

Could not find encoder for codec id 28: Encoder not foundERROR: Failed to write the video
Press any key to continue . . .Below is my code :
int main(int argc, char *argv[])
{
// QApplication a(argc, argv);
VideoCapture cap(0); //capture webcam
if (!cap.isOpened()) //if not successful then exit
{
cout << "Cannot open webcam";
return -1;
}

cap.set(3, 1280);
cap.set(4, 720);
double dWidth = cap.get(CV_CAP_PROP_FRAME_WIDTH); //get width of frames of video
double dHeight = cap.get(CV_CAP_PROP_FRAME_HEIGHT); //get height of frames of video
Size frameSize(static_cast<int>(dWidth), static_cast<int>(dHeight));
cout << "Frame size = " << dWidth << "x" << dHeight << endl;

video=Logitech HD Pro Webcam C920: Immediate exit requested -
What causes Firefox to refuse playing one specific MP4 that plays well on other browsers, resolution being the only difference ?
3 décembre 2014, par FaroI’m a developer for a PHP powered website that allows the upload of videos which get converted to MP4 using ffmpeg. This setup worked pretty well so far, however today I came across a report of a user that couldn’t play one of the files in Firefox.
I was unable to replicate the issue on my own machine at first, but using a fresh install of Windows 7 I actually got the same issue : The file will not play in Firefox, but works fine in Chrome. If called up directly, Firefox will say "Video can’t be played because the file is corrupt".
When downloaded, Windows will also not create a thumbnail of the video for the file and WMP will only play the audio part.On my own machine the file works perfectly in WMP which made me wonder if it could be a codec issue (I do have the K-Lite Codec Pack installed), however I’ve compared the file to a working one and the only difference is the resolution, filesize and the format profile which is "High@L3.1" for a working file with a 720p resolution and "High@L4.0" for the non-working one (which is 1600x1200).
I then read through the Wikipedia article on H.264/MPEG-4 AVC and began to wonder if the level might be the issue, and the tool I used (XMedia Recode) actually did not allow me to set a height bigger than 1080 on Level 4, however when I set the level to 5 and encoded the file again, it still wouldn’t play.
I did find a note on the MDN page of supported formats which reads :
Firefox/Firefox for Android/Firefox OS supports the format in some cases, but only when a third-party decoder is available, and the device hardware can handle the profile used to encode the MP4.
I’m assuming that is why the codec pack would allow Firefox to play even the ’broken’ file on my machine, I still don’t understand though why Firefox does play some files but not this one, especially when Chrome on the same machine plays all of them.
The line in PHP that starts the conversion is as follows :
exec("/usr/local/bin/ffmpeg '-i' '" . $file_in . "' '-qscale' '4' '-y' '-threads' '1' '-acodec' 'libvo_aacenc' '-vcodec' 'h264' '" . $file_out . "' 2>&1", $buffer, $success);This should produce correct files, and this is indeed the first time a file has issues.

Maybe I’m missing something obvious, but I couldn’t find anything wrong with it, what do I need to change in order to produce a file that will work natively in Firefox ?
Also, this is my first question on SO, so if you see anything that I can improve, please let me know :-)
