# 参数获取

视频输出提供参数获取特性，该特性通过对外接口GetParam进行获取。

#### VIDEO_GET_ENCODER_PARAM

通过指定module为DATA_VIDEO，cmd为VIDEO_GET_ENCODER_PARAM，data传入EncodeParams类型数据，可进行编码参数获取。示例如下：

```
VmiDataType module = DATA_VIDEO;
VmiCmd cmd = VIDEO_GET_ENCODER_PARAM;
EncodeParams encodeParams;
uint8_t* param = &encodeParams;
GetParam(module, cmd, param, sizeof(EncodeParams));
```
