本文针对cameraCTSfailed问题，提供了一套详细的解决方案。包括如何判断是前摄还是后摄问题，以及具体的解决步骤，如调整摄像头配置文件和内核参数等。

注意事项：在解决camera CTS failed 时要首先确认是哪一颗摄像头（前摄或后摄）引起的。

判断方法:单独运行报错的cts包(command: run cts -c android.hardware.camera2.cts.ExtendedCameraCharacteristicsTest -m testAvailableStreamConfigs --skip-preconditions --force -abi 32 for example)，如果测试的机器进入了前摄（过程为先测后摄再前摄）才报错，即报错是前摄引起的。

1.android.hardware.camera2.cts.ExtendedCameraCharacteristicsTest--testAvailableStreamConfigs

junit.framework.AssertionFailedError: Required FULLHD size not found for format 100 for: ID 1 : No elements from [,320x240640x4801280x7681280x9601600x912...] in [, 1920x10801920x1088] at junit.framework.Assert.fail(Assert.java:50)

solution:根据FAQ17749

Case 9: CTS测试android.hardware.camera2.cts.ExtendedCameraCharacteristicsTest#testAvailableStreamConfigs fail

junit.framework.AssertionFailedError: Required HD size not found

-> 这条测试项会fail的原因在于: 如果最大的Pic Size超过(或者等于)HD(1280x720), 就必须包含HD的size. 同理，还有其他：

    private static final Size FULLHD = new Size(1920, 1080);
    private static final Size FULLHD_ALT = new Size(1920, 1088);
    private static final Size HD = new Size(1280, 720);
    private static final Size VGA = new Size(640, 480);
    private static final Size QVGA = new Size(320, 240);

所以，我们增加相应的Pic Size.

在对应的摄像头config.ftbl文件中修改如下代码（红色字体为add代码）：

#if 1
// Picture Size
FTABLE_CONFIG_AS_TYPE_OF_DEFAULT_VALUES(
KEY_AS_(MtkCameraParameters::KEY_PICTURE_SIZE),
SCENE_AS_DEFAULT_SCENE(
ITEM_AS_DEFAULT_("640x480"),
ITEM_AS_VALUES_(
"320x240",    //QVGA
  "640x480", //VGA
  "1280x720", "1280x768", //1M
"1280x960", "1600x912", //1.3M
    "1600x1200", "2048x1152", "1920x1088", //2M
)
),
)
#endif

2.android.hardware.camera2.cts.RecordingTest--testBasicRecording和---- testRecordingFromPersistentSurface

junit.framework.AssertionFailedError: Frame rate range [20, 20] (for profile ID 2) must be one of the camera device available FPS range! at junit.framework.Assert.fail(Assert.java:50)

Solution:根据提示看出，是指frame rate range [20 20] 必须要有。在对应的config.ftbl文件中做如下修改：

#if 1
// Preview Frame Rate Range
FTABLE_CONFIG_AS_TYPE_OF_USER(
KEY_AS_(MtkCameraParameters::KEY_PREVIEW_FPS_RANGE),
SCENE_AS_DEFAULT_SCENE(
ITEM_AS_DEFAULT_("30000,30000"),
ITEM_AS_USER_LIST_(
"(15000,15000)",
"(20000,20000)",
"(30000,30000)",
)
),
)
#endif

3.android.hardware.camera2.cts.FlashlightTest-- testCameraDeviceOpenAfterTorchOn/-- testSetTorchModeOnOff/

-- testTorchCallback/-- testTorchModeExceptions

java.lang.IllegalArgumentException: Bad argument passed to camera service at android.hardware.camera2.utils.CameraBinderDecorator.throwOnError(CameraBinderDecorator.java:114)

或

junit.framework.AssertionFailedError: not expecting IllegalArgumentException at junit.framework.Assert.fail(Assert.java:50)

Solution: 如果摄像头有闪光灯效果，在config_static_metadata.project.flashlight.××.h中

STATIC_METADATA2_BEGIN(DEVICE, FLASHLIGHT, SENSOR_DRVNAME_GC0310_MIPI_YUV)
CONFIG_METADATA_BEGIN(MTK_FLASH_INFO_AVAILABLE)
CONFIG_ENTRY_VALUE(MTK_FLASH_INFO_AVAILABLE_TRUE, MUINT8)
CONFIG_METADATA_END()

CONFIG_METADATA_BEGIN(MTK_FLASH_INFO_CHARGE_DURATION)
CONFIG_ENTRY_VALUE(0, MINT64)
CONFIG_METADATA_END()
STATIC_METADATA_END()

反之亦然。
