1. 我们先看看问题背景

   可以看到是单机必现问题

   1：【操作步骤】外屏打开相机视频照片人像来回切换-观察

   2：【实际结果】相机页面卡死，点击没反应

   3：【出现次数/测试次数】【Occurrence Times/Test Times】必现
   4：【恢复方式】【Recovery Method】无法恢复

2. 我们看下kernel日志

   单机必现问题，我们优先看下kernel日志是否报错

   1：imgsensor 4-0010: [imx709_mipi_raw_22023][get_min_shutter_by_scenario] error: invalid、imgisp7s 15000000.

   2：imgsys_fw: mtk_imgsys_worker_power_on: [ERROR] reg is err or null

   3：可以看到kernel日志存在报错，怀疑硬件存在问题

3. 检测工模情况

   1：然后检查工模，发现各个摄像头模组均正常工作

   2：排除硬件问题

4. 继续分析用户态日志

5. 基于日志分析相机流程是否正常

   1：open camera相机流程正常

   2：配流configureSession发现cameraserver createStream了很多个，且很多是重复的。

   3：cameraserver fwk层就已经报错了：createStream: Camera 3: Surface already has a stream created for it (ID 7)

   4：接着camera app报错：Failed to create capture session; configuration failed

   5：发现配流configureSession并没有调用camera hal接口

6. 基于上述分析的结论

   1：配流configureSession失败和camera hal无关

   2：配流configureSession失败由camera app下发导致，需camera app分析。

   3：因此需camera app来分析根因
