Using Handlers

THIS ENTIRE SECTION NEEDS TO BE REWRITTED

When receiving a stream, pystreaming utilizes generators to hand computation between different stream handlers.

The collector handler is used to access frames decoded in the Decoder. If the handler was created with M-R enabled, it yields [arr, meta, idx]. If the handler was created with M-R disabled, it yields [arr, idx].

The collate handler is used to sort frames in chronological order. It expects the datatype (arr, meta, idx) and returns the same datatype. It is suggested to place this immediately after the decoder handler.

The display handler takes a frame and displays it in a OpenCV window.

Getters are used to handle different argument types between the handlers. A common example is using a getter for the display handler.

You can define a custom handler for your own usage (e.g, drawing boxes for object detection).
