Description

I dived shortly into this and detected JavaFXFrameConverter.convert(Frame) to Image is rather slow. Fortunately I found a much faster conversion alternative which uses kind of PixelBuffer of JavaFx. I am no expert in this but it looks like it is an extreme enhancement:

Contributor guide

Research direction
