• Call to Process works fine with Debug, but it doesn't work in the installed application

  6 février 2019, par Santi

  I am developing a Windows Form program that has callings to ffmpeg library through the class Process.

  It works fine when I run it with the Debug in Visual Studio 2013. But when I install the program and I invoke the operation that call to the ffmpeg Process, it doesn’t work. The cmd screen appears an disappears and nothing happens.

  I have tried to know what can be happening getting a log file with the output of ffmpeg, in case it was a problem in the ffmpeg libraries. However, after executing it the log is empty, what means that the ffmpeg command has not been executed.

  Can someone help me, please ?

  The code is this :

  ProcessStartInfo startInfo = new ProcessStartInfo();
  
  startInfo.FileName = "cmd.exe";
  
  startInfo.Arguments = "/c " + ffmpegPath + " " + commandArguments;
  
  using (Process processTemp = new Process())
  
  {
  
      processTemp.StartInfo = startInfo;
  
      processTemp.EnableRaisingEvents = true;
  
      processTemp.Start();
  
      processTemp.WaitForExit();
  
  }

  I am invoking to cmd.exe (not directly ffmpeg.exe) because in the arguments sometimes there can be a pipe (that is why the command starts with "/c").

• Ffmpeg throws File Not Found Error in Python but works fine in terminal

  6 avril 2022, par Abhishek Bhadola

  I am trying to concatenate audio and video in my pc through ffmpeg, wrote a code for that

  


  input_video=str("E:\\Downloaded\\temp\\2 Types of knapsack.mp4")
input_audio=str("E:\\Downloaded\\temp\\2 Types of knapsack.mp3")

print(input_video)

subprocess.run([
            "./ffmpeg",
            "-i",
            f"{input_video}",
            "-i",
            f"{input_audio}",
            "-c",
            "copy",
            "E:\\Downloaded\\2 Types of knapsack.mp4"
        ])


  


  now when i try to run the code in python it crashes and throws me an error that the file,path is wrong,but the same ffmpeg command written in terminal works fine

  


  ffmpeg -i "E:\Downloaded\2 Types of knapsack.mp4\2 Types of knapsack.mp4" -i "E:\Downloaded\2 Types of knapsack.mp4\2 Types of knapsack.mp3" -c "E:\Downloaded\2 Types of knapsack.mp4"


  


  any fixes.?

  


• uwp app throw error when install from package but works fine in any mode when run directly launching from visual studio

  30 septembre 2020, par Abhishek Sharma

  I have created an app wrapping FFmpeg in uwp now for the requirement
I have all the major dll of FFmpeg and then set to content and copy always in property
now when I launch the app installed from the visual studio in any mode weather release, debug, x86,x64 it works fine but as I created a package and then install the app and run it, it throws an error where it says that dll not found not directly but says file not found which is because of dll because I face that problem in debug mode before and it's because of dll not available to uwp
