How to produce() for FrameDisplayStage
Hi,
I'd like to visualise images outputted by a custom stage. To do that, I'm inheriting from BaseStage and now need to call produce(xxx) appropriately. I saw that the class FrameDisplayStage tries to cast the input to FrameData in the function set_consuming_callback (line 77 of frame_display_stage.h) and a FrameData is a std::pair<timestamp, FramePtr> (and a FramePtr is a SharedObjectPool<cv::Mat>::ptr_type). But calling produce(std::pair<double, cv::Mat>) is not working. What is the correct way then, to produce data for a FrameDisplayStage?
What might be helpful would be to share the implementation for frame_generation_stage.cpp, since this should contain all the details (perhaps as part of the tutorial).
Many thanks!
