和你一起终身学习，这里是程序员Android

经典好文推荐，通过阅读本文，您将收获以下知识点:

一、高通相关网址
二、高通平台调试手段

一、高通相关网址

Createpoint:
https://createpoint.qti.qualcomm.com（可下载文档，Release Note，Case，文档，工具等等）
Chipcode:
https://chipcode.qti.qualcomm.com（下载私有代码）
开源代码:
https://www.codeaurora.org/xwiki/bin/QAEP/release（下载开源代码）
Case:
https://support-qualcomm.force.com/（高通Case）
高通网站 image 转换工具：

二、高通平台调试手段

调试平台信息：【SDM845/670】

以下为参考用例，具体请以 sdm845_caf\vendor\qcom\proprietary\camx\src\core\camxsettings.xml 为准！！！

Camx 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

或


adb shell "echo autoImageDumpMask=6>>/vendor/etc/camera/camxoverridesettings.txt"
adb shell "echo offlineImageDumpOnly=TRUE>>/vendor/etc/camera/camxoverridesettings.txt"
adb shell "echo reprocessDump=TRUE >>/vendor/etc/camera/camxoverridesettings.txt"
adb shell "echo autoImageDump=TRUE>>/vendor/etc/camera/camxoverridesettings.txt"
...

生成路径：++data/misc/camera/++ 或 ++data/vendor/camera/++

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> 
CAMX_NAMESPACE_BEGIN
@@ -99,6 +100,28 @@ VOID ImageDump::Dump(
OsUtils::SNPrintF(suffix, sizeof(suffix), "ERROR"); 
break; 
}
+// add format mask 
+ char value[100] = "\0"; 
+ static int nFirstTime = 1; + static int nDumpMask = 0; 
+ if(nFirstTime) 
+ { 
+ 　　property_get("persist.camera.dump.formatmask", value, "0"); 
+ 　　nFirstTime = 0; 
+ 　　nDumpMask=atoi(value);
+ } 
+ if(nDumpMask > 0) 
+ { 
+ 　if(static_cast<INT32>(pDumpInfo->pFormat->format) != nDumpMask) 
+ 　{ 
+ 　　　CAMX_LOG_ERROR(CamxLogGroupUtils, "stop dump format: %d, only dump format: %d\n", pDumpInfo->pFormat->format, nDumpMask);
+ 　　　return; 
+ 　} 
+ } 
+  
+//

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\）


adb shell "echo tuningDumpDataSizeIFE=5000 >> /vendor/etc/camera/camxoverridesettings.txt"
adb shell "echo tuningDumpDataSizeBPS=20000 >> /vendor/etc/camera/camxoverridesettings.txt"
adb shell "echo tuningDumpDataSizeIPE=150000 >> /vendor/etc/camera/camxoverridesettings.txt
