  Core framework and AV1 only for now.

  a module outside libavcodec.

• 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.?
