  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • ffmpeg fails to convert an uploaded video file whose size greater than 14mb when executed through c#.net

    10 novembre 2017, par Harun

    I am converting videos to flv using ffmpeg.exe through c# and the process gets stuck and the conversion fails if the file size exceeds 14mb. I’ve tried to run ffmpeg directly through command prompt and it works fine regardless of size.

    My conversion code is as follows :

    OutputFile = SavePath + "SWF\\" + WithOutExt + ".flv";
    
FilArgs = string.Format("-i {0} -ar 22050 -qscale 1 {1}",InputFile,OutputFile);
    

    
Process proc;
    
proc = new Process();
    

    
try
    
{
    
     proc.StartInfo.FileName = spath + "\\ffmpeg\\ffmpeg.exe";
    
     proc.StartInfo.Arguments = FilArgs;
    
     proc.StartInfo.UseShellExecute = false;
    
     proc.StartInfo.CreateNoWindow = false;
    
     proc.StartInfo.RedirectStandardOutput = true;
    
     proc.StartInfo.RedirectStandardError = true;
    
     proc.Start();
    

    
     string StdOutVideo = proc.StandardOutput.ReadToEnd();
    
     string StdErrVideo = proc.StandardError.ReadToEnd();
    
 }
    
 finally
    
 {

  • 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"
