详细说明： wen_ov5640_r16_20161114_1744后插入UVC可以打开ov5640和USB摄像头.7z 20161114全志R16配置为前ov5640后UVC的双摄像头 1、 Z:\home\wwt\uvc_r16_project\android\device\softwinner\astar-evb20\configs\camera.cfg 修改： number_of_camera = 1 为： number_of_camera = 2 如果不改这里，兄弟，你在camera这个APP里面是绝对看不到前后摄 像头的切换选项的！！！！^_ 修改ov5640的分辨率： used_preview_size = 1 key_support_preview_size = 640x480 key_default_preview_size = 640x480 used_picture_size = 1 key_support_picture_size = 640x480 key_default_picture_size = 640x480 为（根据你驱动里面的摄像头的寄存器配置分辨率而实际修改）： used_preview_size = 1 key_support_preview_size = 2592x1936, 2048x1536, 1600x1200, 1280x960, 1280x960, 1024x768, 1920x1080 ,1280x720, 800x600, 640x480 key_default_preview_size = 640x480 used_picture_size = 1 key_support_picture_size = 2592x1936, 2048x1536, 1600x1200, 1280x960, 1280x960, 1024x768, 1920x1080 ,1280x720, 800x600, 640x480 key_default_picture_size = 640x480 2、 Z:\home\wwt\uvc_r16_project\android\device\softwinner\astar-evb20\astar_evb20.mk #include device/softwinner/polaris-common/prebuild/google/products/gms_minimal.mk 注释掉这里干掉Google Play。可以不改。 3、这里讲UVC配置为模块了，请注意UVC所需要的模块的加载顺序。 Z:\home\wwt\uvc_r16_project\android\device\softwinner\astar-evb20\init.sun8i.rc 默认为： #csi module insmod /system/vendor/modules/videobuf-core.ko insmod /system/vendor/modules/videobuf-dma-contig.ko
