关于sub sensor的角度 问题

[DESCRIPTION]
关于mainsensor和subsensor的角度问题
[SOLUTION]
1.mediatek/custom/common/hal/CAMERA/camera/cfg_tuning_MT6573.h
或者mediatek/custom/common/hal/camera/camera/MT6577/cfg_setting_imgsensor.h
getSensorOrientation()里修改：
u4Degree_0表示main//通常横装的是90度
u4Degree_1表示sub//subsensor竖装是0都，横装的90/270度
2.xxxyuv_Sensor.c
xxx_Preview()和xxx_Capture()
必须调用xxxSetMirror(sensor_config_data->SensorImageMirror);
也必须正确的实现xxxSetMirror()函数
3.另外注意：
xxxGetResolution()里previw的Width/Height都必须小于capture的，这样才能区别preview和capture,参考下面的修改：

1. pSensorResolution->SensorFullWidth=xxx_IMAGE_SENSOR_WIDTH_DRV;
   
2. pSensorResolution->SensorFullHeight=xxx_IMAGE_SENSOR_HEIGHT_DRV;
   
3. pSensorResolution->SensorPreviewWidth=xxx_IMAGE_SENSOR_WIDTH_DRV-2;
   
4. pSensorResolution->SensorPreviewHeight=xxx_IMAGE_SENSOR_HEIGHT_DRV-2;

复制代码

4.xxxControl()也得把preview和capture分开，请参考例子（之前有些driver只用了一路）

1. switch(ScenarioId)
   
2. {
   
3. caseMSDK_SCENARIO_ID_CAMERA_PREVIEW:
   
4. casEMSDK_SCENARIO_ID_VIDEO_PREVIEW:
   
5. caseMSDK_SCENARIO_ID_VIDEO_CAPTURE_MPEG4:
   
6. xxx_Preview(pImageWindow,pSensorConfigData);
   
7. break;
   
8. caseMSDK_SCENARIO_ID_CAMERA_CAPTURE_JPEG:
   
9. caseMSDK_SCENARIO_ID_CAMERA_CAPTURE_MEM:
   
10. xxx_Capture(pImageWindow,pSensorConfigData);
    
11. break;
    
12. default:
    
13. returnERROR_INVALID_SCENARIO_ID;
    
14. }
