android - 使用 Camera2 设置记录提示

Question

什么是setRecordingHint的Camera2等价物？

Answer 1

使用请求模板TEMPLATE_RECORD。

Answer 2

它应该和 previewRequest.set(CaptureRequest.CONTROL_CAPTURE_INTENT, CameraMetadata.CONTROL_CAPTURE_INTENT_VIDEO_RECORD);

例如

     CaptureRequest.Builder previewRequest = camera.createCaptureRequest(CameraDevice.TEMPLATE_RECORD);
     previewRequest.addTarget(previewSurface);
     previewRequest.set(CaptureRequest.CONTROL_CAPTURE_INTENT, CameraMetadata.CONTROL_CAPTURE_INTENT_VIDEO_RECORD);
     session.setRepeatingRequest(previewRequest.build(), null, null);
