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

  24 mars 2017, 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 :

  2017-03-24T11:06:00.705 Function started (Id=df082f54-719a-415f-b7f1-b10548a213be)

  2017-03-24T11:11:00.758 Microsoft.Azure.WebJobs.Host: Timeout value of 00:05:00 was exceeded by function: Functions.ManualTriggerCSharp1.

  When I try to execute this same command on KUDU console or my own PC it only take 1.5 mins and I get a file of the desired duration

  Could anyone please help me with this ? What I might be missing ?
