  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Possibilité de déploiement en ferme

    12 avril 2011, par

    MediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
    Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

  • Video file not trimming and copying using FFMpeg in C#

    15 mai 2019, par chapperzuk

    I am trying to clip a video using C# in Visual Studios with FFMpeg. I run the code below and it doesn’t come back with any errors, except it doesn’t create a new video file.

    I’ve looked around here to make sure I’m using the correct code, but after multiple attempts it still won’t copy.

    string videoFile = @"C:\Users\dave\Documents\video 1.mp4";
    
string outputFile = @"C:\Users\dave\Documents\video 2.mp4";
    

    
Process process = new Process();
    
process.StartInfo.RedirectStandardOutput = true;
    
process.StartInfo.RedirectStandardError = true;
    
process.StartInfo.FileName = @"C:\Users\dave\Documents\ffmpeg.exe";
    
process.StartInfo.Arguments = "ffmpeg -i " + videoFile + " -ss 00:30:00 -t 00:00:10 -c copy " + outputFile;
    
process.StartInfo.UseShellExecute = false;
    
process.StartInfo.CreateNoWindow = true;
    
process.Start();

    I was expecting to get a video cut from the original video, starting at the 30 second mark and lasting 10 seconds, but nothing is created.

    I am using the latest FFMpeg from https://ffmpeg.zeranoe.com/builds/

    UPDATE If I run the code in command prompt - The file comes out corrupt though

    ffmpeg -i "C:\\Users\\dave\\Documents\\video 1.mp4" -ss 00:30:00 -t 00:00:10 -c copy "C:\\Users\\dave\\Documents\\video 2.mp4"

  • How to extract anamorphic video frame correctly using ffmpeg ?

    12 mai 2019, par user10246830

    I can extract the frames using below ffmpeg but it comes out 720x576 square pixel instead of anamorphic non-square 1024x576. How do I output 720x576 rectangle pixel as shown on TV ?

    How do i deinterlace the frames as output is interlaced ?

    ffmpeg -i Midnight.vob -vf fps=1,setdar=16:9 -q:v 2 Midnight%06d.jpg

    How do i deal with this below in ffmpeg.

    [swscaler @ 0000000002a8ec40] deprecated pixel format used, make sure
    you did set range correctly. Video : mjpeg, yuvj420p(pc).

    Am I to understand that the video colour format is out of date and that (pc) is the range 0-255 for colours ?

    Settled on for large jpg to render then shrink to 1024x576. If deinterlace remove yadif=1.

    ffmpeg -i input.vob -vf yadif=1,scale=4096x2304,setdar=16:9 -qmin 1 -q:v 1 output%06d.jpg

    Jpg is original size 1024x576 square pixel.

    ffmpeg -i input.vob -vf yadif=1,fps=1,scale=iw*sar:ih,setsar=1 -qmin 1 -q:v 1 output%06d.jpg

    Png gives better quality over jpg.

    Thanks for your contributions.
