Command for putting watermark on video

I tried to put watermark on one video but FFmpeg command won't execute and error code is 3037. I run the same code for trimming video and video is trimmed successfully so there is no issues with inputpath or outputpath also I have ic_watermark.png in assets folder. I tried with image from Drawable but same error code.

So here is the command which I tried to run and put watermark in right corner:

String[] cmd = new String[]{"-i", videoInputPath, "-i", imagePath, "-filter_complex", "overlay=main_w-overlay_w-5:main_h-overlay_h-5", videoOutPath };

and this is the whole method:

private void executeFFmepg(String inputPath, String outputPath, String customCommand){
final Command command = videoKit.createCommand()
        .overwriteOutput()
        .inputPath(inputPath)
        .outputPath(outputPath)
        .customCommand(customCommand)
        .experimentalFlag()
        .build();
 new AsyncCommandExecutor(command, this).execute(); 
 }

I used one library based on FFmpeg: https://github.com/inFullMobile/videokit-ffmpeg-android and description says that this is basically invoking FFmpeg main() with CLI arguments.

This is what I get from Log:

I tried many answers from similar questions but none of them worked.

Is possible that error is in quotes?

I don't have experience with FFmpeg so any help would be very appreciated. Thanks

If anyone has the issue in future with putting watermark on video here is how you can do it. This can be done using writingminds compiled FFmpeg library: http://writingminds.github.io/ffmpeg-android-java/

Follow the instructions how to setup FFmpeg into your project. After that by running this command I was able to put watermark on video:

        String commands[]={"-y","-i",videoInputPath,"-i", imagePath,"-filter_complex","[1:v]scale=200:200 [ovrl], [0:v][ovrl]overlay=main_w-overlay_w-5:main_h-overlay_h-5:enable='between(t,"+0+","+timeInSec+")'","-codec:a","copy","-strict","-2","-c:v","libx264","-preset","ultrafast",videoOutPath};

videoInputPath - is path of video

imagePath - is path of an image from external storage. I tried by using image from Drawable but didn't find that working (not saying it's not possible)

timeInSec - is length of video which you can get from MediaMetadataRetriever:

    File videoFile = new File(path);
    MediaMetadataRetriever retriever = new MediaMetadataRetriever();
    retriever.setDataSource(this, Uri.fromFile(videoFile));
    String time = retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
    long timeInMillisec = Long.parseLong(time );
    timeInSec = (int) (timeInMillisec /1000);

videoOutPath - path where video is going to be saved after putting watermark

Command above will also scale watermark on 200:200 you can adjust according to your needs and put it in bottom right side.
