Command for putting watermark on video

Question

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

Answer 1

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.
