• Using FFMPEG in C#

  26 juin 2012, par k_1404

  I am trying to strip audio from a video file using FFMPEG in C#. I know what the code is for doing such an operation (as far as I know) but I am not 100% sure where I need to keep the ffmpe.exe file in my project and how to access it.
  My code so far is as follows :

  public void stripAudioTest(string videoFilename, ExportProgressWindow callback, string destinationAudioFile)
  
      {
  
          string FFMPEG_PATH = "*************"; //not sure what to put here??????
  
  
  
  
  
  
  
          string strParam = " -i " + videoFileName + " -ab 160k -ar 44100 -f wav -vn " +   destinationAudioFile;
  
          process(FFMPEG_PATH, strParam);
  
          callback.Increment(100);
  
  
  
  
  
      }
  
  
  
      public void process(string Path_FFMPEG, string strParam)
  
      {
  
          try
  
          {
  
              Process ffmpeg = new Process();
  
  
  
              ffmpeg.StartInfo.UseShellExecute = false;
  
              ffmpeg.StartInfo.RedirectStandardOutput = true;
  
              ffmpeg.StartInfo.FileName = Path_FFMPEG;
  
              ffmpeg.StartInfo.Arguments = strParam;
  
  
  
              ffmpeg.Start();
  
  
  
              ffmpeg.WaitForExit();
  
  
  
          }
  
          catch (Exception ex)
  
          {
  
              MessageBox.Show(ex.Message);
  
          }
  
      }`

  If anyone has any ideas please let me know. Anything helps !

• Android : How to record the mobile screen without using USB cable ?

  21 juin 2012, par Rajesh

  I want to build an application which would record my screen activities and would store them in a video file.

  1) I need to take the screenshots of my screen movements at periodic intervals and store them on the SD card.

  2) How can I create the video from the images which are already available on my SD card. I have tried with the FFMPEG. But I have encountered a few problems I don't know how to solve. The truth is I don't know the program to convert them.

  3 ) Is it possible to show the picture in my camera ?? That means if a user opens the camera from my app, it should show the pictures which are available on the SD card. If so, please advice me.

  EDIT : I have made a sample which can capable of taking 7 screen shots per second.

  Thanks,
  Rajesh .
