AN75779等代码输出的格式默认都是yuy2，可以修改为rgb565等格式，如下：
/* GUID, globally unique identifier used to identify streaming-encoding format: YUY2 */ //0x32595559, 0x0000, 0x0010, 0x80, 0x00, 0x00, 0xaa, 0x00, 0x38, 0x9b, 0x71) #if 0 //yuy2 /*MEDIASUBTYPE_YUY2 GUID: 32595559-0000-0010-8000-00AA00389B71 */ 0x59, 0x55, 0x59, 0x32, 0x00, 0x00, 0x10, 0x00, 0x80, 0x00, 0x00, 0xAA, 0x00, 0x38, 0x9B, 0x71, #else // 0xe436eb7b, 0x524f, 0x11ce, 0x9f, 0x53, 0x00, 0x20, 0xaf, 0x0b, 0xa7, 0x70, //rgb565 0x7b,0xeb,0x36,0xe4, 0x4f,0x52, 0xce,0x11, 0x9f, 0x53, 0x00, 0x20, 0xaf, 0x0b, 0xa7, 0x70, #endif具体的uuid类型可以在uuids.h中查看，也可参考下面的网页: http://blog.okbase.net/zaboli/archive/394.html
