Hi want to create a android app in which user can capture video. While capturing the video, a watermark should be shown in each frame, such that when the video is played afterwards it has an embedded watermark.
Has anyone worked on this before?

While questioning do not explicitly ask for code, First tell the community what you have done and then share the error you have faced. – Jeru Luke Jan 14 '17 at 11:44

To embed a watermark, you need to have an image with 4 channels namely: Red, Blue, Green and Alpha (transparency). All you have to do is extract this alpha channel and overlay it on top of the frames in the video.
How do you overlay an image?
