一.查看是否存在camera外设,设备节点

ls /dev/video*

二.adb 查看camera 详细信息

2.1.adb shell dumpsys media.camera

2.2.adb 查看camera 过滤信息

查看某一项参数,使用过滤命令grep(linux), windows下可使用findstr来过滤

dumpsys media.camera |grep picture-size

//Camera preview 相关信息

picture-size-values: 640x480,1920x1080,1600x1080,1280x720,640x360,352x288,176x144,160x120,848x480,320x240

2.3.adb 保存camera信息

adb shell dumpsys media.camera > C:\Users\Administrator\Desktop\camera.txt
