  • Installation en mode ferme

    4 février 2011, par

    Le 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 (...)

  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • How to embed subtitles to .mp4 movie using ffmpeg

    25 novembre 2016, par hudac

    I’m trying to embed subtitles I wrote to a movie I created.
    I’m using FFmpeg version : ffmpeg-20150418-git-edbb9b5-win64-static with the command :
    ffmpeg -i in.mp4 -f srt -i subs.srt -c:v copy -c:a copy -c:s mov_text out.mp4 I saw here.

    But I get errors during the process, and when the process is done there’s an output file out.mp4 without subtitles embedded.
    When I play the in.mp4 in some player such as media player classic with the subtitles separately, the subtitles are sync and everything is fine.

    The subtitles are subrip encoded in UTF8.

    I tried to look out for these errors but didn’t find anything useful. it seems something ridiculous.
    What am I doing wrong ?

    Errors such as :

    [mp4 @ 00000000003fe020] Codec for stream 0 does not use global headers but container format requires global headers
    
[mp4 @ 00000000003fe020] Codec for stream 1 does not use global headers but container format requires global headers

  • How can I start ffmpeg while playing a full screen game ?

    11 janvier 2021, par Muhamed Shair benshair

    This is a class of the ffmpeg :

    


    using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using System.Threading.Tasks;  
using System.IO;  
using System.Diagnostics;  
  
namespace Ffmpeg_App  
{  
    class Ffmpeg  
    {  
        Process process;  
  
        public void Start(string FileName, int Framerate)  
        {  
            process = new System.Diagnostics.Process();  
            process.StartInfo.FileName = @"D:\ffmpegx86\ffmpeg.exe"; // Change the directory where ffmpeg.exe is.  
            process.EnableRaisingEvents = false;  
            process.StartInfo.WorkingDirectory = @"D:\ffmpegx86"; // The output directory  
            process.StartInfo.Arguments = @"-f gdigrab -framerate " + Framerate + " -i desktop -preset ultrafast -                                                                     pix_fmt yuv420p " + FileName;  
            process.Start();  
            process.StartInfo.UseShellExecute = false;  
            process.StartInfo.CreateNoWindow = false;  
            Close();  
        }  
  
        public void Close()  
        {  
            process.Close();  
        }  
    }  
}  


    


    And in form1 :

    


    At the top :

    


    Ffmpeg fmpeg = new Ffmpeg();


    


    In a button click event :
To start :

    


    private void Start_Click(object sender, EventArgs e)  
        {  
            fmpeg.Start("test.mp4", 24);  
        }


    


    and to stop :

    


    private void Stop_Click(object sender, EventArgs e)  
        {  
            fmpeg.Close();  
        }


    


    The problem is when I'm in full screen game I don't have access to the form and the buttons they are hidden in the background.

    


    I need to make some global keys hook maybe ?
