MacOS | Gtuner IV doesn't properly request camera permissions

[misterpyrrhuloxia]

EDIT:
I've changed the title of this issue to report an actual bug with Gtuner IV, i.e. Gtuner doesn't properly request camera permissions from MacOS.

I've put my original issue in a quote block below. Following that is more detail on the Gtuner bug that led to my problem as well as my workaround for the meantime.

Forum post: https://www.consoletuner.com/forum/viewtopic.php?f=25&t=17393&p=108777#p108777

My setup:

Gtuner IV: 1.10.3.1
Titan Two: 1.10.3.1
MacBook Pro (Retina, 15-inch, Mid 2015)
MacOS 11.1 Big Sur
2.8 GHz Quad-Core Intel Core i7
16 GB ram

T2 > OUT > PC
T2 > PROG > Macbook Pro
PC GPU > HDMI 2.0 cable > AverMedia Live Gamer Ultra capture card > USB 3.1 C to A cable > MacBook Pro
PC GPU > DisplayPort cable > gaming monitor

I am trying to set up my MacBook Pro to do Gtuner CV capture. In Windows, the capture card is recognized as a second display. I can duplicate my display and I can extend it. While it's set to extended, I even set the capture card to output in 1920x1080@60Hz. Regardless of whether Windows is set to duplicate display or extend it, and regardless of what resolution I set Windows to output the capture card to while it's in extended mode, Gtuner completely crashes the moment I click on 'Detect Devices' in the Gtuner CV video input config options. It should be noted that no matter which configuration I set Windows to, OBS on my Macbook can detect and use the capture card perfectly.

@J2Kbr found in a Gtuner crashlog file that I sent him that Gtuner doesn't properly request camera permissions from the OS, which leads to MacOS terminating Gtuner when you try to hit Detect Devices in CV. In the meantime, I'm using a hackjob workaround to at least get Gtuner temporary camera permissions. I do this by launching Gtuner from the terminal with this command:

/Applications/GtunerIV.app/Contents/MacOS/Gtuner

Then when I hit Detect Devices, Gtuner properly requested camera permissions- except it was the terminal requesting the permissions from the OS, not Gtuner. But after granting the permissions, my capture card is detected. The annoying thing is that I have to run Gtuner from the terminal every single time. In addition to that, I have to hit Detect Devices again each time I run Gtuner.

Please update Gtuner to properly request camera permissions from MacOS.

I've updated this issue description and title to reflect the bug that needs to be addressed to fix the underlying problem I was experiencing.

Feature implemented, to be released on next Gtuner IV update. Thanks.
