请求正文
请求正文中包含结构如下的数据：
| JSON 表示法 |
{
"expression": {
object (Expression)
},
"description": string,
"videoOptions": {
object (VideoOptions)
},
"fileExportOptions": {
object (VideoFileExportOptions)
},
"requestId": string,
"workloadTag": string,
"priority": integer
} |
| 字段 |
expression |
object (Expression)
一个表达式，其求值为要计算和导出的视频，表示为图片集合。
|
description |
string
任务的直观易懂的名称。
|
videoOptions |
object (VideoOptions)
用于描述要生成的视频的基本选项。
|
fileExportOptions |
object (VideoFileExportOptions)
用于选择视频的导出位置和格式的选项。
|
requestId |
string
用于检测重复请求的唯一字符串。如果同一用户发出多个包含相同非空 requestId 的请求，则其中只有一个请求可以成功启动长时间运行的操作。requestId 可以包含字符 a..z、A..Z、0-9 或“-”。requestId 的长度不得超过 60 个字符。
|
workloadTag |
string
用户提供的用于跟踪此计算的标签。
|
priority |
integer
可选。项目中导出任务的优先级。系统会更早地安排优先级较高的任务。必须是介于 0 到 9999 之间的整数。如果未设置，则默认为 100。
