Tutorial simple videoloop capture

Yes, we're rapidly developing and the API is evolving but we're happy to help out if you need anything :)

It sound like you need a separate process for streaming in the data and another for rendering the frames. We have a multiprocessing example that uses zmq: https://github.com/fastplotlib/fastplotlib/tree/main/examples/notebooks/multiprocessing_zmq

I have one thread for capture using vidgear, another for videowrite and in the main thread the GUI
But opencv is terrible for showing a simple video if you want high fps or same as real time

You can use fastplotlib to display frames received from another process, the zmq example I linked above shows how to do it. The CONFLATE option in zmq allows you to display only the most recent frame so that the rendering process doesn't create a backlog (you may receive frames faster than the refresh rate of your monitor).

fig = fpl.Figure()
      ^^^^^^^^^^

AttributeError: module 'fastplotlib' has no attribute 'Figure'

My installation was with pip. Should I install from the repository?
