              String cmd[] = new String[]{"ffmpeg", "-i", "/storage/emulated/0/Videos/dheere.mp4", "-c:v", "libx264", "/storage/emulated/0/Videos/dheere2.3gp"};

    private void execute(String cmd[]) {
  
  
  
  
  
      try {
  
          // to execute "ffmpeg -version" command you just need to pass "-version"
  
          FFMpegApp.getFfmpeg().execute(cmd, new ExecuteBinaryResponseHandler() {
  
  
  
              @Override
  
              public void onStart() {
  
                  Log.e("gc", "Command Started");
  
              }
  
  
  
              @Override
  
              public void onProgress(String message) {
  
                  Log.e("gc", "onProgress" + message);

              public void onFailure(String message) {
  
                  Log.e("gc", "onFailure command" + message);
  
              }
  
  
  
              @Override
  
              public void onSuccess(String message) {
  
                  Log.e("gc", "onSuccess command" + message);
  
              }

              }
  
          });
  
      } catch (FFmpegCommandAlreadyRunningException e) {
  
          // Handle if FFmpeg is already running
  
          e.printStackTrace();

• ffmpeg pipe input and output in Python

  4 juin 2021, par MinasCham

  I want to use ffmpeg to read an RTSP stream, extract frames via a pipe, do some processing on them with Python and afterwards combine the processed frames via another pipe with the original audio. I'm using the subprocess module in Python to execute the ffmpeg command as well as read and write the frames from and to ffmpeg.

  


  Questions :

  


  

  1. Is it possible to pipe both stdin and stdout so as to extract the frames and then feed them back in after the processing ?

  


  2. Do i also have to pipe the audio separately and feed it with the processed frames or can i simply copy the audio stream when mapping the output ?
