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、MTK Camera 预览流程
二、MTK Camera Trace 启动流程拆解

一、MTK Camera 预览流程

1.1 MTK camera app 预览大致流程

  1. Camera app 开始准备Open Camera call到Camera Service的 connect call 开始链接底层
  2. Camera FWK 响应 camera app 下发的open 动作
  3. Camera HAL 开始响应 下发的 open session
  4. open阶段为了启动速度，开始CPU提频进入perf模式
  5. Camera hal 层开始响应startOpenDevice attachOpenDeviceLocked
  6. Camera HAL 初始化 pipline 一些静态信息，调用Sensor HalDeviceAdapter 开始power on createInstance --> initSensor -->setSensorMclk 上电流程
  7. Camera HAL 初始化闪光灯
  8. Camera APP 检查open state 状态 CAMERA_OPENING，并匹配最合适的预览size，拍照size、缩略图size
  9. Camera app 创建会话请求后开始配流请求，
  10. Camera app 创建会话 开启配流
  11. 配置并申请 buffer
  12. OTP lsc校准数据获取
  13. 3A Hal、ISP Hal、 Sensor power on流程结束，开始向上callback 通知poweron 流程结束
  14. 预览场景需要走的Feature feature combination: MTK_CAMERA_SCENARIO_STREAMING_NORMAL
  15. 解析配流size ，parseStreamSize_4Cell select size 尺寸，选择sensormode
  16. 决策 P1 IMGO && RRZO 配置影响功耗
  17. 决策预览size ，FD size，sensor 出图size
  18. 开始配流
  19. 开始build P1 stream流信息
  20. pipeline context dump 预览流、拍照流、流经的node
  21. AppStreamMgr 配3路流 预览： 1280x720 ；拍照：4080x2296 ； 缩略图：160x96
  22. Camera app 创建会话结束 配流结束
  23. OTP 数据获取
  24. 配流结束，Camera APP 用于在CameraCaptureSession中设置预览请求，以实现连续的相机预览或视频录制等功能
  25. Camera HAL 开始准备第一帧预览请求 [submitRequest] <4Cell/0> requestNo:0
  26. Camera FWK 第一帧请求ok
  27. Camera HAL 出图并callback result 到上层 Frame timer: 预览出图 frame end updateResult callback 预览帧到上层

1.2 MTK camera app 预览 流程 log如下：

二、MTK Camera Trace 启动流程拆解

1.MTK Camera app 启动阶段拆解表格

启动阶段模块trace 关键字
S0系统deliverInputEvent(AppLaunch_dispatchPtr:Up桌面相机图标点击事件处理 ) ⇒ activityStart或Camera APP 进程创建
S1Camera APPactivityStart或Camera APP 进程创建 ⇒ connectDevice
S2Camera HALconnectDevice
S3Camera APPconnectDevice end ⇒ CameraHal::configureStreams start
S4Camera HALCameraHal::configureStreams
S5Camera APPCameraHal::configureStreams end ⇒ setRepeatingRequest start
S6Camera HALsetRepeatingRequest start ⇒ first full buffer
S7Camera APP、SFfirst full buffer ⇒ 第一帧显示(onPreviewOk)

2 MTK Camera 预览流程trace 拆解

2.1 S0：AppLaunch_dispatchPtr:Up /deliverInputEvent (桌面相机图标点击事件处理) --> APP 进程创建

和你一起终身学习，这里是程序员Android

点击事件 Trace TAG：
AppLaunch_dispatchPtr:Up
deliverInputEvent

2.2 S1： activityStart或Camera APP 进程创建 ⇒ connectDevice

从Touch UP 到 ActivityStart 阶段，系统创建App进程耗时：

和你一起终身学习，这里是程序员Android

Camera APP 进程创建trace TAG
PostFork
ZygoteInit
ActivityThreadMain
bindApplication
activityStart
Activity.onCreate
activityResume

  • 1.PostFork 耗时需要排查 Zygote.java 代码

Zygote.java frameworks\base\core\java\com\android\internal\os

    1. ZygoteInit 耗时需要排查ZygoteInit.java 代码

ZygoteInit.java frameworks\base\core\java\com\android\internal\os

  • 3.ActivityThreadMain耗时需要排查ActivityThread.java代码

ActivityThread.java frameworks\base\core\java\android\app

    1. bindApplication 耗时需要排查ActivityThread.java代码,同上
    1. 从 ActivityStart 到 App 层 OpenCamera 耗时

Camera App 开始执行 MainActivity 一系列 onCreate，onStart，onResume，openCamera等操作

和你一起终身学习，这里是程序员Android

5.1. activityStart 耗时需要排查 LaunchActivityItem.java 代码
LaunchActivityItem.java frameworks\base\core\java\android\app\servertransaction
5.2. ResumeActivityItem耗时需要排查 ResumeActivityItem.java 代码
ResumeActivityItem.java frameworks\base\core\java\android\app\servertransaction
5.3. Choreographer#doFrame 耗时需要排查 Choreographer.java 代码
Choreographer.java frameworks\base\core\java\android\view

  • 6.Framework层 cameraserver 开始响应App getCameraCharacteristics 、connectDevice 等操作。
camera Server 在此期间的行为

open camera 前的Trace TAG
getCameraCharacteristics
connectDevice

2.3 S2: connectDevice

和你一起终身学习，这里是程序员Android

连接Camera 期间的Trace TAG：

connectDevice
CameraHal::openSession
mtkcam-devicemgr:finishOpenDevice

2.4 S3: connectDevice end ⇒ CameraHal::configureStreams start

Camera app 下发opensession后，底层开始对sensor 进行poweron上电处理

2.4.1 power on 上电 trace

Android Camera2-预览、拍照、录像流程
xiaowang_lj的博客

重复模式（Repeating）：指的是不断重复执行指定的 Capture 操作，当有其他模式的 Capture 提交时会暂停该模式，转而执行其他被模式的 Capture，当其他模式的 Capture 执行完毕后又会自动恢复继续执行该模式的 Capture，例如显示预览画面就是不断 Capture 获取每一帧画面。在 Camera2 上，你可以在规定的曝光时长范围内配置拍照的曝光时间，从而实现拍摄长曝光图片，你甚至可以延长每一帧预览画面的曝光时间让整个预览画面在暗环境下也能保证一定的亮度。

MTK-Camera Capture、Preview request解析
gfpsgo:gfpsgo
04-16
适用于Linux的gfpsgo 概述 gfpsgo是ps （ 1 ）（与AIX格式兼容）的Go库和工具，并扩展了各种描述符，这些描述符可用于显示与容器相关的数据。 与ps （ 1 ）工具一样，该库背后的想法是提供一种易于使用的提取与过程相关的数据的方法。 使用ps （ 1 ）的问题是ps输出是格式化的字符串，该字符串被空格分隔成几列，这使得输出极不可能自动解析。 这也增加了一些抖动，因为我们必须在容器中派生并执行ps ，或者随后对输出进行过滤，这进一步限制了可用性。 该工具和库旨在使事情变得更舒适，尤其是对于容器运行时。 API允许加入给定进程的mount名称空间，并将自动解析/proc和/dev/文件系统。 该API包含以下功能： gfpsgo.ProcessInfo(descriptors []string) ([][]string, error) ProcessInfo返回

如下图所示，我是直接过滤搜索 Stream configuration。从图片内容我们可以看到，当前占用相机的app,一共申请了2路流，分别是 0x22 1280 *720 和 0x21 1280 *720。我们可以通过dumpsys media.camera 命令，能获取到当前使用相机的情况，在保存的文件里面，过滤搜索 Stream configuration，就能找到我们想要的信息。如果只是抓logcat日志，我们可能没法从中获取到有效信息，毕竟一般出货的机器版本，基本已经把大部分相关日志都给关闭了。
