Save depth and colour stream at 24fps

Hi Guys,

I’m working on the iOS viewer app using the latest SDK (0.11.2) and sensor mark 2.
I would like to save the depth and colour stream at 24fps as a sequence of images inside the file app.
Any hints how I could achieve that?

I have this config key kSTCaptureSessionOptionColorMaxFPSKey: @(30.0f)
Can I just use any value? Or does it need some other configuration to have it in 24fps

Thank you for your help
