How to add watermark while recording video using ffmpeg

I am recording square video using the following ffmpeg library. The square video was recorded successfully with audio, but now I want to add a watermark to the video, but my app crashed and got an error. Please help me how to add watermark while recording video.

Gradle dependency

compile(group: 'org.bytedeco', name: 'javacv-platform', version: '1.3') {
    exclude group: 'org.bytedeco.javacpp-presets'
}
compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '3.2.1-1.3'
compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '3.2.1-1.3', classifier: 'android-arm'

      

        
        
        
      

    

I am using the following code to add a watermark while recording a video

     // add water mark
            String imgPath = audioPath + "jodelicon.png";
            String watermark = "movie=" + imgPath + " [logo];[in][logo]overlay=0:0:1:format=rgb [out]";
            filters.add(watermark);
