Android 平台支持使用即插即用的 USB 摄像头(即网络摄像头),但前提是这些摄像头采用标准的 Android Camera2 API 和摄像头 HIDL 接口。网络摄像头通常支持 USB 视频类 (UVC) 驱动程序,并且在 Linux 上,系统采用标准的 Video4Linux (V4L) 驱动程序控制 UVC 摄像头。
如果系统支持网络摄像头,设备便可用于视频聊天和照片冲印机等轻量级用例。此功能不能替代 Android 手机上典型的内部相机 HAL,也不是为了协助执行涉及高分辨率和高速流式传输、AR 以及手动 ISP/传感器/摄像头控制且对性能要求很高的复杂任务。
USB 相机 HAL 进程是外接摄像头提供程序的一部分,该提供程序会监听 USB 设备可用性,并相应地枚举外接摄像头设备。该进程具有与内置相机 HAL 进程类似的权限和 SE 策略。直接与 USB 设备通信的第三方网络相机应用访问 UVC 设备时所需的相机权限与所有常规相机应用所需的权限相同。
