#### 说明

定义H.264 Slice码流的参考类型，预留，暂不支持。


#### 定义

```
typedef enum {
HI_VENC_H264_REF_SLICE_FOR_1X = 1, // Reference slice for H264E_REF_MODE_1X
HI_VENC_H264_REF_SLICE_FOR_2X = 2, // Reference slice for H264E_REF_MODE_2X
HI_VENC_H264_REF_SLICE_FOR_4X = 5, // Reference slice for H264E_REF_MODE_4X
HI_VENC_H264_REF_SLICE_FOR_BUTT // slice not for reference
} hi_venc_h264_ref_slice_type;
```
