• How can I apply custom font on watermark that created by FFmpeg

  7 août 2019, par Dens

  I am creating a video with FFmpeg library. I want access fonts from Android assets folder and overlay on my video as watermark.

  What is the path for Android assets folder to access and apply custom font on FFmpeg ?
  I can overlay watermark on video but when I try to apply custom font on it, it gives error related to not exist, etc.

  What I found till now :

  The alternative solution that I found is the create an image file and write text on it and overlay image on video. problem is text and image being stretch output. I need a solution for it.

  String[] execute = {"-y",  "-i",  videoPath, "-i", image, "-filter_complex",
  
               "[1:v]scale=" + width + ":" + height + "[ovrl],[0:v][ovrl]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2"
  
               ,"-strict" , "experimental", "-vcodec", "libx264" , "-preset",  "ultrafast" , "-crf",  "20", "-acodec",  "aac",  "-ar",
  
               "44100",  "-ac",  "2",  "-b:v",  "36000k",   outputPath.getPath()};

  I thought itz output will be good but it stretching my text and image.

  I want some perfect solution to apply assets font on FFmpeg.

  Thank you in Advance.

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

  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();
  
      }

• How can i add a watermark on videos ? [duplicate]

  This question already has an answer here :

  • How to add transparent watermark in center of a video with ffmpeg ?

  This is my code that i’m using to merge videos .

   var_dump(shell_exec( "C:/ffmpeg/bin/ffmpeg.exe -f concat -safe 0 -i   D:/xampp/htdocs/test/file.txt -c copy D:/xampp/htdocs/test/phpconcatenated.mp4 2>&1"));

  But this code is working only when all videos is with same number of frames/second . and if frames per second are different for each other then it merge videos with only sounds with pause screen .
