rk3399 usbcamera.apk

新买的开发板RK3399外接USB摄像头，查看了下，RK3399 Android系统rom是支持底层UVC驱动的，将一些测试结果和测试demo记录下来，以免他人踩坑，如果有帮到你，请点个关注和start，谢谢

文章目录

一、USB摄像头连接信息打印

1. Camera启动USB摄像头

  • 当打开不存在相机时warn错误警告，监听该异常处理即可。几个错误问题：

    • 相机分辨率不支持问题，打开报错（系统相机默认打开的640*480），需要从HAL层进行修改
    • USB拔插地址问题，RK3399外接USB摄像头，默认时从/dev/video0地址，通过V4L2去打开。但是不确定时硬件USB接口问题还是驱动问题，导致偶尔拔插会出现Video1识别，导致打开失败的问题

  • 获取Camera支持的分辨率列表，当USB摄像头不在列表之内，系统相机打开崩溃，当然自己软件调用相机没有问题

      打开不存在相机时warn错误警告，监听该异常处理即可
