[RFC] [Android] setting custom capture options for Camera2 API #15369
Description
For more specialized use cases, it is sometimes necessary to set custom capture options, particularly since the Camera2 API allows quite a number of different settings. Recent example, where I just directly edited JavaCamera2View.java:
try {
mPreviewRequestBuilder.set(CaptureRequest.CONTROL_AF_MODE,
- CaptureRequest.CONTROL_AF_MODE_CONTINUOUS_PICTURE);
+ CaptureRequest.CONTROL_AF_MODE_OFF);
mPreviewRequestBuilder.set(CaptureRequest.CONTROL_AE_MODE,
CaptureRequest.CONTROL_AE_MODE_ON_AUTO_FLASH);
+ mPreviewRequestBuilder.set(CaptureRequest.LENS_FOCUS_DISTANCE, 0.0f);
+ mPreviewRequestBuilder.set(CaptureRequest.LENS_OPTICAL_STABILIZATION_MODE,
+ CameraMetadata.LENS_OPTICAL_STABILIZATION_MODE_OFF); Unfortunately, I don't really have a good idea how to solve this in a generic way, i.e. expose the RequestBuilder object to the app. Suggestions?
