RK Android11原始系统 USB摄像头默认只支持到1080P的分辨率，客户需要接1200W USB摄像头，需要拍照和预览都能达到1200W

首先修改配置文件device/rockchip/common/external_camera_config.xml：

     <!-- See ExternalCameraUtils.cpp for default values of Device configurations below--><Device><!-- Max JPEG buffer size in bytes--><MaxJpegBufferSize  bytes="6291456"/>  <!-- 3MB (~= 1080p YUV420) --><!-- Size of v4l2 buffer queue when streaming >= 30fps --><!-- Larger value: more request can be cached pipeline (less janky) --><!-- Smaller value: use less memory -->
