uvc_get_gain
你用的是get方法，当然设置没效果了，要用set方法。。。。。。。。

我这边能自己去设置增益度吗?  如果可以的话我是直接赋值还是?

int gainvalue = 3;
int bc = 4;
  int ret= mpu.getmConnection().UVCControl(
                  BVPU_ExtCamControlParam.uvc_set_gain, gainvalue );
         ret = mpu.getmConnection().UVCControl(
                  BVPU_ExtCamControlParam.uvc_set_backlight_compensation, bc );
if(ret>=0){
//success
}

如果这个代码无效  麻烦提供下新的设置增益度的代码

哦，估计是修改代码冲掉了，再认证一下即可。
