Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...) -
MediaSPIP en mode privé (Intranet)
17 septembre 2013, parÀ partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.
Ce système peut être particulièrement utile pour certaines utilisations comme : Atelier de travail avec des enfants dont le contenu ne doit pas (...)

Extract frames from a large video c#
21 janvier 2014, par lasI am developing a video editing software.
For that I need to first load a video for editing.
After loading the video I need to create a timeline of the video with its Thumbnail images which should take in every one seconds.I have tried many options for that but still have an issue with more 10 - 15 mins videos.
First I used ffmpeg.
There I tired two options.They ended up with following resultsOne is very slow
Another one is fast but thumbnails are not accurate
Next I used Aforge.Net
There I can save images to disk but cannot access after 2000-3000 thumbnails
(It gives out of memory exception)Please if you have good suggestion let me know for this task.
Any one like to see my tried code samples let me know , I will add it to this question.Following is the method for reading images which are in the Disk
void AddThumbnailImages(int i)
{
PictureBox pictureBox = new PictureBox();
pictureBox.Size = new System.Drawing.Size(100, 75);
pictureBox.Image = (Bitmap)new Bitmap("Snaps\\" + i + ".jpeg").Clone();
if (i == totalFrames)
{ pictureBox.Tag = totalTimeForFrames; }
else { pictureBox.Tag = (i / frameRate); }
pictureBox.MouseClick += new MouseEventHandler(ViewImageTag);
pictureBox.MouseDoubleClick += new MouseEventHandler(videoCuting);
pictureBox.MouseHover += new EventHandler(pictureBox_MouseHover);
pictureBox.SizeMode = PictureBoxSizeMode.Zoom;
pictureBox.BringToFront();
pictureBox.Location = new Point(pictureBoxlocationX + (100 * (i/frameRate)), pictureBoxlocationY);
panelTimeline.Controls.Add(pictureBox);

How to paint in Qt using hardware acceleration ?
19 octobre 2020, par FennecFixI need to do some quite intensive drawing processes in my appliation - I'm recording a camera and a desktop. I'm using
ffmpeg
to capture and encode/decode my videos. Those processes are quite fast and they working in a separate thread, but when it comes to render - perfomance drops drastically. I'm usingQLabel
to display captured frames viasetPixmap()
method and I see that Qt not using any GPU power even if a matrix operation, such as scaling an image to fit the window is clearly implied. Is there any way to paint images in Qt using hardware acceleration ? Or is there another ways to speed up painting process ?
