Log信息相关
--AF相关LOG控制--
例： setprop persist.vendor.camera.logInfoMask 0x8000000 //AF info level log
setprop persist.vendor.camera.logVerboseMask 0x8000000 //AF verbose level log
adb shell "echo logInfoMask=0x8000000 >> /vendor/etc/camera/camxoverridesettings.txt"
adb shell "echo logVerboseMask=0x8000000 >> /vendor/etc/camera/camxoverridesettings.txt"
Mask值对应如下：(1 << 27)=0x8000000 即对应AF模块

使用Chromatix 工具查看：
① *.RAWMIPI → rename to *.RAW, *.YUV420NV21 → Rename to *.YUV
② RAW → BPP 10, pack: mipi pattern: RGGB YUV → BPP 8, Sub-sample: Ycbcr420, Format: Semi-Planar
开启dump后预览会比较卡，可以修改dump部分代码(/src/utils/camximagedump.cpp b/src/utils/camximagedump.cpp)，过滤特定格式缓解卡顿：
#include "camximagedump.h"
#include "camximagebuffer.h"
#include "camximageformatutils.h"
#include <cutils/properties.h>

+// 然后可以参考 “camxformats.h”中的掩码定义dump指定的图像格式：
adb shell setprop persist.camera.dump.formatmask 15 // dump YUV420NV12TP10（2）将 TP10 转换成 YUV 10bit 格式
dump到大量TP10格式的YUV文件后，模拟器不能直接支持TP10格式，需要使用Chromatix 7将其转换为Yuv420_10bit的格式，转换步骤如下：
1.打开chromatix 7并打开您的项目。
2.选择视频场景（ video Scenario）。
3.打开TF界面，检查宽度和高度。TF界面中显示的宽度和高度应与文件名中的宽度和高度完全相同。(xxxx[WW]_[HH]xxxx.YUV420NV12TP10）如果不相同，请先更正。
3.1 你需要关闭Chromatix7. 然后进入Chromatix7 工程目录。
3.2 打开并修改 sensorData.txt 中的宽和高。（C7project\Scenario.Default\Sensor.0\Usecase.Video\sensorData.txt，路径取决于您使用的场景）
3.3 修改以下两行并保存，然后再执行第3步。
2036, /* raw image width */
1144, /* raw image height */ 4. 点击 “TP10 to Planar” 并选择重命名的yuv文件，您只需要选择xxx_0.yuv，工具就可以找到剩余的文件，然后选择输出文件夹。
5. 等几秒钟，您就可以得到输出名如 xxx_pln_0.YUV, xxx_pln_1.YUV … 的文件，所有的tp10文件都被转换了。
（3） Get Meta
步骤： ① 设备开启meta
② 拍照获得jpeg
③ 通过C7获取meta （QualcommSpectraSim280.exe - metaparsetest.jpg -》 C7\Simulator\Spectra280\）
