Allow splitter component to process still images #184

Closed techyian closed 3 years ago

techyian commented 3 years ago

A new port needs creating which extends StillPort with a similar override to Configure so that a user can connect the splitter component to the camera's still port.

This appears to be working well, however if the user intends on outputting via image encoders then they must add a Resize/ISP component between the splitter output port and the image encoder input port. If the user doesn't do this, the splitter component only seems to allow 1 encoder component to be connected to any given splitter output port. Raw capture from the splitter works well too.

The default constructor for a splitter component will instantiate 4 SplitterVideoPort objects to be used for its output ports which are intended for video recording functionality. The user can override this when configuring the output port by using SplitterStillPort as a generic constraint.

I've added some documentation around this which should hopefully be clear on how to use the splitter component with the camera's still port.
