Android 7.0 GMS测试 Camera模块CTS fail项分析
2024-05-14 23:16:53
在上一篇博客中我们提到Camera模块fail项，本篇博客我们单独讲解Camera模块的。
GMS中涉及Camera的有：
1、CTS部分的CtsCameraTestCases模块
2、CTS VERIFY测试的Camera模块，其中verify部分还包括Camera FOV角的计算
3、其他问题
这里面CTS 的CtsCameraTestCases模块fail项又分为Camera Sensor 部分和HAL层的分辨率配置两大块。
一、Camera Sensor模块的fail项
首先我们截取一部分关键log去分析：Camera-JNI: release camera

01-11 08:23:41.707 7670 26697 I TestRunner: ----- end exception -----从上述log中我们大概可以看到摄像头帧率范围是7-30（MIN~MAX）帧，当前配置的是浮动帧率，报错的时候帧率只有5帧，报错后摄像头直接打不开，可想而知这个模块剩下的测试项将是全部fail。
既然是帧率的问题，我们要搞懂它的原理然后再去配置。一般在做客制需求时客户都会要求摄像头芯片厂 FAE去调摄像头的效果。在我与这些FAE的打交道中了解到，摄像头的帧有一定的范围，比如最大是30帧，根据客户要调的效果，FAE一般会调成浮动帧率，这样摄像头的拍照效果很更好。但是CTS的要求更为严格，CTS对于帧率的测试，是允许有一定量的误差值，但测量出的帧率与目标范围相差过大时，就会fail，且现在预览帧率都为AE自动调整，当测试环境不同时，结果也可能不同，如上log 中实际帧率只有5帧就会fail。使用平台默认的浮动帧率配置，前后摄会有几组不同的帧率范围，如测试环境复杂时，就会容易fail。所以解决方案是：过CTS的时候出现帧率fail就将摄像头效果调成固定帧率。
第一步：从FAE那里拿到摄像头模组调成固定帧率的效果文件。比如在当前项目中他给我调的前后摄都是25帧
第二步：同步修改SprdCamera3Setting.cpp文件里面的kavailable_fps_ranges_back和kavailable_fps_ranges_front数组。
vendor/sprd/modules/libcamera/hal3/SprdCamera3Setting.cpp 里面
const int32_t kavailable_fps_ranges_back[] = {5, 25, 25, 25};//后摄修改之后帧率
//{5, 20, 8, 20, 10, 20, 5, 25, 10, 25, 5, 30, 10, 30};//后摄修改之前帧率
const int32_t kavailable_fps_ranges_front[] = {5, 25, 25, 25};//前摄修改之后帧率
//{5, 15, 5, 20, 10, 20, 5, 25, 10, 25, 5, 30, 10, 30};//前摄修改之前帧率这里面简单介绍下这两个数组的作用。这个数组是控制录像的时候视频的帧率范围。MIN,MAX两两为一组。比如修改之后我的帧率范围有两组分别是5-25 和25-25。因此在录像的时候我们不能出现这个范围之外的帧率，否则录像功能就不能正常的使用下面就要进行我们的第三步。
第三步：修改sc7731g_n/device/sprd\scx35/sp7731g_1h10目录下面的media_profiles.xml文件。这里面media_profiles.xml文件的路径每个平台都不同，不能死记路径，我们可以通过代码查找。
find device/sprd/ -name "media_profiles.xml"
device/sprd/scx35/common/rootdir/system/etc/media_profiles.xml
device/sprd/scx35/sp7731g_1h10/media_profiles.xml这里有两个可能的media_profiles.xml文件，我们需要判断哪个才是代码里面引用的
```
在代码device目录下查找
grep -rn "media_profiles.xml" device/sprd/scx35
device/sprd/scx35/sp7731g_1h10/sp7731g_1h10_common.mk:35:PRODUCT_COPY_FILES += $(BOARDDIR)/media_profiles.xml:system/etc/media_profiles.xml我们打开对应的Makefile文件
TARGET_PLATFORM := sc8830
TARGET_HARDWARE := sp7731g
TARGET_BOARD := sp7731g_1h10
PLATDIR := device/sprd/scx35
PLATCOMM := $(PLATDIR)/common
BOARDDIR := $(PLATDIR)/$(TARGET_BOARD)
ROOTDIR := $(BOARDDIR)/rootdir
ROOTCOMM := $(PLATCOMM)/rootdirBOARD_KERNEL_PAGESIZE := 2048
BOARD_KERNEL_SEPARATED_DT := true#use sprd's four(wifi bt gps fm) integrated one chip
USE_SPRD_WCN := true# copy media_profiles.xml before calling device.mk,
# because we want to use our file, not the common one
PRODUCT_COPY_FILES += $(BOARDDIR)/media_profiles.xml:system/etc/media_profiles.xml
PRODUCT_COPY_FILES += $(BOARDDIR)/media_codecs.xml:system/etc/media_codecs.xml这里面执行copy动作是将sp7731g_1h10目录下的media_profiles.xml文件复制出来，所以代码里面引用的是第二个路径下的文件。
我们打开media_profiles.xml文件，下面贴出部分代码
<CamcorderProfiles cameraId="0"><EncoderProfile quality="low" fileFormat="mp4" duration="60"><Video codec="h264"bitRate="256000"width="176"height="144"frameRate="15" /><Audio codec="amrnb"bitRate="12200"sampleRate="8000"channels="1" /></EncoderProfile>这里面h264编解码格式的视频尺寸大小为176x144,帧率为15帧，这里面虽然15帧在配置的范围内，但是为了测试顺利，我们将这个文件里面的所有frameRate都改为25帧。同时视频尺寸的宽高也要在我们支持的分辨率里面，下面的分辨率部分将会讲解到。按照上述三步修改，就基本可以解决帧率的fail项。
二、Camera分辨率部分的fail项
从报告的截图中我们可以看到提示说
junit.framework.AssertionFailedError: Required HD size not found for format 100 for: ID 1 : No elements from [,720x480640x480480x640352x288320x240176x144] in [, 1280x720]
在1280x720里面没有找到没有找到720x480 640x480 480x640 352x288 320x240 176x144这些分辨率，下面的同理。
1、配置BroadConfig.mk文件里面的前后摄大小，比如当前项目配置的是gc030a+gc5025前30w 后500w像素的模组
device/sprd/scx35/sp7731g_1h10/BoardConfig.mk
# select camera 2M,3M,5M,8M
CAMERA_SUPPORT_SIZE := 5M
FRONT_CAMERA_SUPPORT_SIZE := 0P3M2、配置vendor/sprd/modules/libcamera/hal3/SprdCamera3Setting.h里面前后摄的最大拍照尺寸
#elif CONFIG_CAMERA_SUPPORT_5M
#define BACK_SENSOR_ORIG_WIDTH 2592
#define BACK_SENSOR_ORIG_HEIGHT 1944
#else
#define BACK_SENSOR_ORIG_WIDTH 1600
#define BACK_SENSOR_ORIG_HEIGHT 1200
#endif#elif CONFIG_FRONT_CAMERA_SUPPORT_2M
#define FRONT_SENSOR_ORIG_WIDTH 1600 //select according to max jpg resolution
#define FRONT_SENSOR_ORIG_HEIGHT 1200
#elif CONFIG_FRONT_CAMERA_SUPPORT_0P3M
#define FRONT_SENSOR_ORIG_WIDTH 640 //select according to max jpg resolution
#define FRONT_SENSOR_ORIG_HEIGHT 480
#else这里面标准的500万像素照片大小是：2592x1944 (2592/1944=4:3) 2592x1944 =5038848
标准30万像素照片大小是 ：640x480 （640/480=4:3）640x480=307200
3、配置vendor/sprd/modules/libcamera/hal3/SprdCamera3Setting.cpp文件里面的分辨率
hal 层的SprdCamera3Setting.cpp文件之前我们有提到过，Camera 底层的分辨率也是在这里面配置的。

};
我贴出来的是其中的一个kavailable_back_stream_configurations数组，以这个为例，我们先看这个数组的代码。
这里有四种格式的数据：
HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED //预览尺寸
{HAL_PIXEL_FORMAT_YV12 //
{HAL_PIXEL_FORMAT_YCbCr_420_888 //录像尺寸
HAL_PIXEL_FORMAT_BLOB //拍照尺寸
这四中格式下面每种格式都有很多分辨率的，而且这个里面有很多if ，else的宏定义需要一点C/C++的知识，并且耐心看代码。
先看后摄500W的HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED数据，类似上面的数据中定义到的500W的尺寸有：
{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 2592, 1944, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},
{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 1600, 1200, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 1280, 960, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 1280, 720, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 960, 720, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 864, 480, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 720, 480, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 640, 480, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 480, 640, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 352, 288, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 320, 240, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 240, 320, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},{HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED, 176, 144, ANDROID_SCALER_AVAILABLE_STREAM_CONFIGURATIONS_OUTPUT},这里面总共有13组数据，2592x1944 - - 176x144。
同样的这个数组里面的其他剩余的3中格式的数据，500W定义的也要是这13组分辨率，要保持一致，不能一组分辨率在这个格式里面有，在另外一个格式里面没有按照这样的原则去配置。其实继续看这个SprdCamera3Setting.cpp里面的代码，我们可以发现前后摄对应的都有三个相同的数组。
后摄：kavailable_back_stream_configurationskavailable_back_min_frame_durationskavailable_back_stall_durations前摄：kavailable_front_stream_configurations kavailable_front_min_frame_durations kavailable_front_stall_durations
这三个数组都按照前面的方法配齐，这样既可以保证不会分辨率的fail 项了。三、其他问题
这里面有一个android.hardware.camera2.cts.AllocationTest#testAllocationFromCameraFlexibleYuv
fail
junit.framework.AssertionFailedError: Input allocation data was not updated
testAllocationFromCameraFlexibleYuv要求callback数据不能为全黑数据，否则case会失败，
使用如下宏打开该规避方案：
TARGET_FORCE_PASS_FLEXIBLEYUV_IN_DARK := true
该宏在Boardconfig.mk定义 同时修改libcamera 下oemv20目录下 cmr_priview.c文件，
cmr_int prev_pop_zsl_buffer(struct prev_handle *handle, cmr_u32 camera_id, struct frm_info *data, cmr_u32 is_to_hal)
{ CMR_LOGD("valid_num %ld", valid_num); if (prev_cxt->cap_zsl_frm[0].addr_phy.addr_y == data->yaddr && valid_num > 0) { frame_type.y_phy_addr = prev_cxt->cap_zsl_phys_addr_array[0]; frame_type.y_vir_addr = prev_cxt->cap_zsl_virt_addr_array[0];
++ frame_type.width = prev_cxt->prev_param.picture_size.width;
++ frame_type.height = prev_cxt->prev_param.picture_size.height; frame_type.type = PREVIEW_ZSL_CANCELED_FRAME; }
最后我们来总结一下，通篇博客的内容其实很简单。关于CTS Camera 模块的配置就是一句话：固定帧率，对齐分辨率
如果你对这个分辨率的配置还是不太明白，请下载Android 7.0 GMS CtsCameraTestCases模块配置分辨率文档仔细阅读，应该是很容易明白的。
也可以参考我的SprdCamera3Setting.cpp代码去看里面的30w和500w的像素分辨率是怎么配置的。（很尴尬···为什么上传的资源一定要选择积分才能下载，我只能选一个最小的两个积分了···）
