Video from stream

Hello all,

im am trying to implement a computer vision library (opencv) into my vaadin project
basically i manipulate the video frame by frame and i would like to display the outcome real-time in a vaadin Video object.

The problem is that the video only seems to work with an external source from a url, since i dont have a file yet (as it is in the process of creation) .

Is it possible to render the video a frame at a time, lets say from a stream or build it on-the-go via BufferedImage ?

Thank you for the time
