MTK camera CTS 调试遇到的问题及处理方法
一、CTS camera帧率测试不过
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:

问题：拍照速度不够
处理：
