Isa taking control on focus of Logitech Brio 4K?

Bennnid

Hi everyone,

I got a real time drawing cine concert to patch, sometimes the drawer needs to manipulate objects on the foreground, like 30 cm higher/ (nearer the cam) than the drawing,
the Logitech brio 4K works nicely but the focus of the cam can only be manage with their soft or even better with Mac OS app : Webcam Settings 18.17.32,
I would love to be able remote control (midi control or so), the focus and allow the drawer to change focus with preset or continuous controller,

Wouldn't it be great to have options inside izy to do that? I know the newbyness of my question might shock you @mark,
cos each builder has its own driver, but though... one can dream ;-)

One other snaky solution could be to script this change into Mac OS (automator or so) and let Isadora launch/manipulate the script?
is that possible?

THX so much for your brains ! Best regards !

@bennnid this is something I have come across a few times, I might try make something, at least I am curious if it is possible. Can you go to system report and then select cameras a send me a screenshot of what you see?

@bennnid only the operating system version is important.

This is the only solution I can think of:

In Isadora, use Data Array actor to edit a file with a line and value for each parameter you want to control.
In Isadora, have the Data Array actor save the file every time you edit it.
Have an Automator script monitoring the folder in which the file lives, triggering the script when the file has been updated.
When Automater sees the file has been updated, have it read the file.
Based on what Automater reads in the file, use Applescript to make the appropriate changes to the settings in Webcam Settings 18.17.32

@woland

Thanks a lot for thé Logic aspect, hope i ll manage Automator well enough... i m a bit afraid not to be able to access this app that only shows up in the systray...

@bennnid oh, I can't help, I have some patchy code for osc control that is half built already.

There is a standard api, called UVC which seams to be supported by the Brio (as well as most other USB Webcams).
For Linux there is a tool guvcview which supports the control of a lot of USB Webcams based on this API, including the Brio.
Would it be possible (affordable) to code an actor based on this api?
