I am talking about AVCaptureVideoDataOutput.recommendedVideoSettings.
I found sometimes it return nil, there is my test result.
hevc .mov with activeColorSpace sRGB
60FPS -> ok
120FPS -> ok
hevc .mov with activeColorSpace displayP3_HLG
60FPS -> nil
120FPS -> nil
h264 .mov
30FPS -> ok
60FPS -> nil
120FPS -> nil
so, if you don't give a recommend setting, and you don't give a document, how does developer to use it?
