一、CTS camera幀率測試不過

log：

Wanted *at least* 3 times: -> at android.hardware.camera2.cts.RobustnessTest.testOutputCombination(RobustnessTest.java:1500) But was 2 times: -> at java.lang.reflect.Method.invoke(Native Method) ) java.lang.Throwable(Test failed for camera 0: Output combination { [PRIV, PREVIEW] [YUV, PREVIEW] [JPEG, MAXIMUM] } failed due to: captureCallback.onCaptureCompleted( android.hardware.camera2.impl.CameraCaptureSessionImpl@fddb6bb, android.hardware.camera2.CaptureRequest@34673ec7, isA(android.hardware.camera2.TotalCaptureResult) ); Wanted *at least* 3 times: -> at android.hardware.camera2.cts.RobustnessTest.testOutputCombination(RobustnessTest.java:1500) But was 2 times: -> at java.lang.reflect.Method.invoke(Native Method) )

問題：拍照速度不夠

處理：

1、修改iic通訊速率：

3、插值解析度：
