环境

某Android系统的POS机

AndroidSDK: 22 Android: 5.1.1

USB摄像头

intelRealSense

AliFacePayCamera

解决思路

根据网上的教程，先验证设备是否支持UVC。

将Android设备与开发机相连，并启用USB调试

adb shellshell@xxxx:/ $ ls -l /dev/v*crw-rw-rw- system   system    81,   9 2017-12-20 14:18 v4l-subdev0crw-rw-rw- system   system    81,  10 2017-12-20 14:18 v4l-subdev1crw-rw-rw- system   system    81,  19 2017-12-20 14:18 v4l-subdev10crw-rw-rw- system   system    81,  20 2017-12-20 14:18 v4l-subdev11crw-rw-rw- system   system    81,  11 2017-12-20 14:18 v4l-subdev2crw-rw-rw- system   system    81,  12 2017-12-20 14:18 v4l-subdev3crw-rw-rw- system   system    81,  13 2017-12-20 14:18 v4l-subdev4crw-rw-rw- system   system    81,  14 2017-12-20 14:18 v4l-subdev5crw-rw-rw- system   system    81,  15 2017-12-20 14:18 v4l-subdev6crw-rw-rw- system   system    81,  16 2017-12-20 14:18 v4l-subdev7crw-rw-rw- system   system    81,  17 2017-12-20 14:18 v4l-subdev8crw-rw-rw- system   system    81,  18 2017-12-20 14:18 v4l-subdev9crw-rw-rw- system   system    81,   0 2017-12-20 14:18 video0crw-rw-rw- system   system    81,   1 2017-12-20 14:18 video1crw-rw-rw- system   system    81,   2 2017-12-20 14:18 video2crw-rw-rw- system   system    81,   3 2017-12-20 14:18 video3crw-rw-rw- system   system    81,   4 2017-12-20 14:18 video4crw-rw-rw- system   system    81,   5 2017-12-20 14:18 video5crw-rw-rw- system   system    81,   6 2017-12-20 14:18 video6crw-rw-rw- system   system    81,   7 2017-12-20 14:18 video7crw-rw-rw- system   system    81,   8 2017-12-20 14:18 video8crw-rw-rw- system   system    10,  42 2017-12-20 14:18 vr

插拔USB设备，再来一次

没有任何变化，看来要不摄像头不支持UVC，要不就是没发现设备。

判断一个设备是否支持UVC协议

adb shellcd sys/bus/usb/driversls

如果存在uvcvedio文件夹则是支持协议

后来研究了下设备，目前排除AliFacePay摄像头，它采用的调用方式是OpenNI2,下面转入OpenNI2的研究。

android设备带宽不够
