Feature: Incremental camera control values

[NoahCallaway]

Firstly, thanks for the camera control implementation.

I'm looking to increment some of the values rather than define a fixed value e.g. increasing/decreasing the camera gain. I've attempted to use variable expressions as described here but it looks like the module doesn't support that yet?

I'm not sure that using expressions is the ideal solution anyway as it could result in values above or below the allowed range at which point the below error occurs:

warn Instance/Wrapper/atem Error executing action: The value of "value" is out of range. It must be >= -128 and <= 127. Received 130

How would you feel about a separate action (or expanding the existing ones) to increment the values up/down?

I've been experimenting on a fork and initially would look to replicate across:

• Video Gain
• Video Exposure
• Lens Iris

Any feedback, suggestions and ideas are welcome!

I'm trying just now to do something simiilar. It seems that value is a stirng, and not a number, so, just as example assume that the value of the variable il "2", the expression ?(atem:camera_1_gain) returns "2" and adding the string "10" set the new value to "210" and not the number 12. Isn't that? In case, is there a way to convert the returned value "2", convert it to the number 2, add avalue and then convert it again to a string to pass as to the method to set a new value?

I've got it working with a dedicated action now: https://github.com/bitfocus/companion-module-bmd-atem/assets/24882928/cd9dbea8-bd3e-440b-afbd-da0e355b2791

Will raise a PR to implement this and some other actions.

I'm looking for a way to increment the IRIS value, but as far as I know, at the moment there is no way to do that. Am I wrong?

[NoahCallaway]

@vbMizio - there is no way to do that at the moment. I've included the functionality in my PR #293. Just waiting for a review/feedback.

[vbMizio]

@NoahCallaway Thank you Noah, we have to wait.

This will be in the betas shortly

[vbMizio]

Thank you @Julusian

[NoahCallaway]

@vbMizio - I found some issues with the initial implementation which you'll probably hit too. Have resolved them in #297

@NoahCallaway Thank you Noah
