How to apply watermark on video in Android​

If you want to apply watermark on video, you should pass WatermarkInfo into the videoOutput.start method.

Drawable watermarkDrawable = ContextCompat.getDrawable(this, R.drawable.my_watermark_resource);
int watermarkWidth = 101;
int watermarkHeight = 24;
float aspectRatio = watermarkWidth / watermarkHeight;
SizeProvider sizeProvider = viewportSize -> {
    int targetWidth = (int) (viewportSize.getWidth() * 0.5f);
    int targetHeight = (int) (targetWidth / aspectRatio);
    return new Size(targetWidth, targetHeight);
};
PositionProvider positionProvider = new GravityPositionProviderAdapter(sizeProvider, Gravity.BOTTOM | Gravity.RIGHT);
WatermarkInfo watermarkInfo = new WatermarkInfo(watermarkDrawable, sizeProvider, positionProvider, watermarkWidth, watermarkHeight, true);
videoOutput.start(..., watermarkInfo);
