How to get sample buffer to vision handler?
Hi, I have two questions regarding the ActionAndVision sample application. After setting up the live AVSession how exactly and in which function is the sample buffer given to a visonhandler to perform a vision request. (for e.g. the getLastThrowType request) When and how is the captureOutput(...) func in the CameraViewController called? (line 268 ff) I appreciate any help, thank you very much.

VNDetectTrajectoriesRequest: Minimum and maximum size
Hi, in which measurement unit are the diameters expected by the VNDetectTrajectoriesRequest when specifying a minimum and maximum size? For example: A soccer ball has a diameter of roughly 22 cm. Is the expected size then (if its meters?): request.minimumObjectSize = 0.17 / videoWidth request.maximumObjectSize = 0.27 / videoWidth ? Thanks for your help!

ActiveFormat tells my that my iPhone 12 Pro Max only supports 30 frames per second
Hi, I've set up a captureSession and am now trying to set the framerate to 60. I am using an iPhone 12 Pro Max. I am trying to set the frame rate with: videoDevice?.activeVideoMinFrameDuration = CMTimeMake(value: 1, timescale: 60), but printing my .activeFormat tells me my iPhone only supports 30 fps. What am I doing wrong? Thanks
