Delay acumulation with gstreamer and opencv

[DaneLLL]

Hi,
We have seen performance issues if there are heavy operations in prob functions. A similar topic:

Hi, Too many operations in prob function may slow down the whole pipeline. You may check if you can use gstreamer plugins tee and queue to implement the usecase.

Is it possible to link to appsink plugin and use OpenCV functions in it?
