概述 UVC USB video class又称为USB video device class or UVC就是USB device class视频产品在不需要安装任何的驱动程序下即插即用包括摄像头、数字摄影机、模拟视频转换器、电视卡及静态视频相机。
测试代码 Camera cam Camera.open(CAMERA_ID);Camera.Parameters param cam.getParameters();ListCamera.Size sizes param.getSupportedPreviewSizes();打印出来后显示支持的预览分辨率如下
D startPreview support preview 640x360
D startPreview support preview 640x480
D startPreview support preview 960x540
D startPreview support preview 800x600
D startPreview support preview 1280x720
D startPreview support preview 1280x960
D startPreview support preview 1920x1080
D startPreview support preview 1600x1200然而把摄像头接入到PC上不管是LINUX还是WINDOWS会发现实际支持的最大预览分辨率是3840x2160 缺少的分辨率哪去了
分析 摄像头部分的架构比较复杂整理几个相关的源码目录 # SDK 接口frameworks/base/core/java/android/hardware/Camera.javaframeworks/base/core/jni/android_hardware_Camera.cpp# 上层 Camera 服务frameworks/av/camera/# HAL层hardware/rockchip/camerahardware/interfaces/camera/# 配置文件对应USB和CSI之类的摄像头配置
# 包含了支持分辨率闪光灯等等的一些特性。device/rockchip/common/external_camera_config.xmlhardware/rockchip/camera/etc/camera/烧录到主板后相关的一些文件目录 rk3568_r:/ # ll /vendor/etc/camera/
