Question

在编译时从服务器获取rtmp的问题我得到了这4个错误： * NewClass.as，Line 30 1120：访问未定义的属性nc。 * NewClass.as，Line 31 1120：访问未定义的属性nc。 * NewClass.as，Line 32 1120：访问未定义的属性nc。 * NewClass.as，Line 33 1120：访问未定义的属性nc。 * NewClass.as，第41行1120：访问未定义的属性nc

我被困了没有想法该怎么做

relationship = data.height / data.width;

//Aspect ratio calculated here..

_aspectH = (_stageH - _videoH) / 2;

vid.x = 0;
vid.y = _aspectH;
vid.width = _videoW;
vid.height = _videoH;
}
    }
}
