So I've been monkeying around with Postman and Companion. The basic functionality is straightforward but I'm having some issues with some of the finer elements of control.
Right now I can use PUT to configure any setting directly to the value chosen. For several parameters this is fine, anything that only has a handful of variables like frame rate, LUT, ISO, compression.
The issue arises when trying to control more granular functionality, WB, aperture, focus, color correction, etc., I can set the WB to 5600 but I can't figure out a way to increment it to say 5700 without directly entering 5700. The Red RCPV2 API has some useful functions which allow increment/decrement and set relative functions. It seems like the SDI/Bluetooth protocol Operation Type 1: offset/toggle value achieves the same function. Is there anything similar in the rest API?
I'm experimenting with variables in companion combining GET/PUT commands but I can't GET clean data. GET url/video/gain returns the JSON { "gain": 6 }. If I could return 6 clean then I could create an expression that queried the current value and added whatever increment seems appropriate. Any smart guys have some advice?
Edit: Using Postman I can extract just the value and avoid the extraneous syntax using Java but I can't figure it out using the Companion Generic HTTP Module.
Good Luck
