• Android ffmpeg : Use image for Watermark from drawable or assets folder

  17 septembre 2019, par Pratik Butani

  How to use image for watermark from drawable folder or assets folder in Android.

  I found many examples with command but all the examples are working with static image path of internal storage.

  I have done following code to make video with watermark.

      try {
  
          FFmpeg ffmpeg = FFmpeg.getInstance(mContext);
  
          // to execute "ffmpeg -version" command you just need to pass "-version"
  
  
  
          String mSelectedPath = PathUtils.getPathFromUri(mContext, selectedUri);
  
          String mFileName = PathUtils.getFileName(mSelectedPath);
  
          final String mDestinationPath = "/storage/emulated/0/" + mFileName;
  
  
  
          String[] array = new String[]{"-i", mSelectedPath , "-i", "/storage/emulated/0/logo.png", "-filter_complex", "[0:v][1:v]overlay=main_w-overlay_w-10:10", "-codec:a", "copy", mDestinationPath};
  
  
  
          ffmpeg.execute(array, new ExecuteBinaryResponseHandler() {
  
  
  
              @Override
  
              public void onStart() {
  
                  Log.d(TAG, "onStart: ");
  
                  Toast.makeText(mContext, "Preparing video...", Toast.LENGTH_SHORT).show();
  
              }
  
  
  
              @Override
  
              public void onProgress(String message) {
  
                  Log.d(TAG, "onProgress: " + message);
  
                  Toast.makeText(mContext, "Processing for compression...", Toast.LENGTH_SHORT).show();
  
              }
  
  
  
              @Override
  
              public void onFailure(String message) {
  
                  Log.d(TAG, "onFailure: " + message);
  
                  Toast.makeText(mContext, "Failed to upload, Try Again.", Toast.LENGTH_SHORT).show();
  
              }
  
  
  
              @Override
  
              public void onSuccess(String message) {
  
                  Log.d(TAG, "onSuccess: " + message);
  
                  Toast.makeText(mContext, "Uploading started", Toast.LENGTH_SHORT).show();
  
                  mFinalUploadUri = PathUtils.getUriFromPath(mContext, new File(mDestinationPath));
  
                  uploadVideo();
  
              }
  
  
  
              @Override
  
              public void onFinish() {
  
                  Log.d(TAG, "onFinish: ");
  
  
  
              }
  
          });
  
      } catch (FFmpegCommandAlreadyRunningException e) {
  
          // Handle if FFmpeg is already running
  
          e.printStackTrace();
  
      }

  Anyone know how to use image for watermark from drawable or assets folder ? Can anyone help ?

   psiProcInfo.CreateNoWindow = true;
  
  
  
   prcFFMPEG.StartInfo = psiProcInfo;
  
  
  
   prcFFMPEG.Start();

  There is no response that I push the start button that I tried to fix the code that I inserted the logo in the movie with Ffmpeg. Is that be okay if I don't choose the path of logo File. and Is there any something wrong that I did.
