#### 说明

定义MJPEG编码通道VBR属性结构。暂不支持。


#### 定义

```
typedef struct {
hi_u32
stats_time; // RW; Range:[1, 60]; the rate statistic time, the unit is senconds(s)
hi_u32
src_frame_rate; // RW; Range:[1, 240]; the input frame rate of the venc channel
hi_u32
dst_frame_rate; // RW; Range:[1, 240]; the target frame rate of the venc channel,
// can not be larger than src_frame_rate
hi_u32
max_bit_rate; // RW; Range:[2, 614400];the max bitrate
}hi_venc_mjpeg_vbr;
