iOS camera focus control (or auto-focus)

Open vanoak opened this issue 3 years ago • 5 comments

Hello,

First of all this is not an issue, the plugin works as expected. I have a doubt though. Is it possible to change the camera focus ? Or enable auto-focus? Thank you.

Noticed this [p_device setFocusMode:AVCaptureFocusModeLocked]; in plugins/camera/camera_ios.mm (line 75). Could it be the case of changing to continuousAutoFocus?

It's possible to use AVCaptureFocusModeContinuousAutoFocus instead of AVCaptureFocusModeLocked, but it would change the way plugin works for everyone, since Godot's CameraFeed doesn't support any way to setup focus modes.

Alright, I think that can work for the project I'm working at the moment. I will try it tomorrow.

Hi again,

It works (just the continuous autofocus). I recompiled the xcframework (debug and the release) and duplicated the previous configuration.

Thank you @naithar.

@vanoak that's great news :) I think plugin should provide the way to setup some parameters like focus, but I can't think of any way to add this configuration except for extending Godot's CameraFeed
