  • using ffmpeg in Azure function to cut files using c#

    22 janvier 2019, par abhishekmoondra1989

    I have written an Azure function in C# which will cut a big mp4 files into some small duration. I have copied everything that is required (ffmpeg executeable, video file) in home directory via KUDU console. But when I run the the function it runs for more than 5 minutes and it doesn’t give any files in the home directory.

    Function :

    using System;
    
using System.Diagnostics;
    

    
public static void Run(string input, TraceWriter log)
    
{
    
    log.Info("Executing");
    
    using (var process = new Process())
    
    {
    
        process.StartInfo.FileName = @"D:\home\ffmpeg.exe";
    
        process.StartInfo.Arguments = @"-i D:\home\AmnestyInternational.mp4 -ss 00:00:03 -t 00:00:08 -async 1 D:\home\cut.mp4";
    
        process.StartInfo.UseShellExecute = false;
    
        process.StartInfo.RedirectStandardOutput = true;
    
        process.StartInfo.RedirectStandardError = true;
    
        log.Info(Directory.GetCurrentDirectory());
    
        log.Info("Cutting starts:"+DateTime.Now.ToString("h:mm:ss tt"));
    
        process.Start();
    
        string output = process.StandardOutput.ReadToEnd();
    
        process.WaitForExit();
    
        log.Info("Cutting ends :"+DateTime.Now.ToString("h:mm:ss tt"));
    
        log.Info(output);
    
    }
    
}

    Output seen on Azure function Console :
