I restarted my iPad mini and it runs OK now.
Thank you very much for all of your help.

RE: Expected __Structure instance instead of __Structure
Thank you very much for checking my code.
@JonB Pythonista 3.2 on iPad mini 5. This code says:
Pythonista version 3.2 (320000) running Python 3.6.1 on iOS 12.3.1 on a 64-bit iPad11,1 with a screen size of (1024 x 768) * 2
.encoding is:
>>> _device.setActiveVideoMinFrameDuration_.encoding b'v40@0:8{?=qiIq}16'
@cvp I assume 3/30 = 10 FPS. It gave the same error without the line
dur.value *= 3
.This error may be specific on iPad mini. -
RE: Expected __Structure instance instead of __Structure
Thank you very much for all of your advices. I still have no luck.
I ran the following code:
from ctypes import * from objc_util import * class CMTime(Structure): _fields_ = [('value', c_int64), ('timescale', c_int32), ('flags', c_uint32), ('epoch', c_int64)] AVCaptureDevice = ObjCClass('AVCaptureDevice') _device = AVCaptureDevice.defaultDeviceWithDeviceType_mediaType_position_( 'AVCaptureDeviceTypeBuiltInWideAngleCamera', 'vide', 1) dur = _device.activeVideoMinFrameDuration(restype=CMTime, argtypes=[]) dur.value *= 3 _device.lockForConfiguration_(None) _device.setActiveVideoMinFrameDuration_(dur, restype=None, argtypes=[CMTime]) _device.unlockForConfiguration()
And I got error:
Traceback (most recent call last): File "/private/var/mobile/Containers/Shared/AppGroup/94D43082-190D-4454-9A0E-256D7C4B8046/Pythonista3/Documents/test.py", line 15, in <module> _device.setActiveVideoMinFrameDuration_(dur, restype=None, argtypes=[CMTime]) File "/var/containers/Bundle/Application/F1D3A05F-66E7-4AD5-8569-D61994DF7737/Pythonista3.app/Frameworks/Py3Kit.framework/pylib/site-packages/objc_util.py", line 897, in __call__ res = objc_msgSend(obj.ptr, sel(self.sel_name), *args) ctypes.ArgumentError: argument 3: <class 'TypeError'>: expected __Structure instance instead of CMTime
activeVideoMinFrameDuration
is a property. Is there any way to specify argument types of a setter? -
Expected __Structure instance instead of __Structure
Hello forum members. Will you tell me how to set activeVideoMinFrameDuration?
I tried the following code:
from objc_util import * AVCaptureDevice = ObjCClass('AVCaptureDevice') _device = AVCaptureDevice.defaultDeviceWithDeviceType_mediaType_position_( 'AVCaptureDeviceTypeBuiltInWideAngleCamera', 'vide', 1) dur = _device.activeVideoMinFrameDuration() dur.a *= 3 _device.setActiveVideoMinFrameDuration(dur)
I got error:

I have read the following topic: https://forum.omz-software.com/topic/2031/videos, but I have had no success so far.
