     "InputClippingSettings": {
      "InputTimecodeSource": "enum",
      "StartTimecode": {
       "Timecode": "string"
      },

      }
     },
     "UrlPath": ["string", ...]
    }
   }

 }
}

切换到固定启动时间的实时输入的示例

此请求示例将在固定启动时间切换到实时输入。切换操作称为 studio-feed，它会切换到连接到名为 live-studio-feed 的输入附件的输入。它会在指定的 UTC 时间切换到此输入。

{
  "ChannelId": "999999",
  "Creates": {
    "ScheduleActions": [
      {
       "ScheduleActionStartSettings": {
          "FixedModeScheduleActionStartSettings": {
            "Time": "2018-05-21T20:42:19.000Z"
           }
          },
      "ActionName": "studio-feed",
      "ScheduleActionSettings": {
        "InputSwitchSettings": {
          "InputAttachmentNameReference": "live-studio-feed" 
     }
    }
   }
  ]
 }
}

静态文件切换为跟随的示例

此请求示例是切换到静态文件输入以跟随前一个输入的结束。切换操作称为 action-ad-003，它会切换到连接到名为 zel-cafe 的输入附件的输入。当名为 action-ad-002 的操作结束时，它会切换到此输入。此操作的文件会被剪辑，使其在 30 秒零 11 帧后结束：

{
  "ChannelId": "999999",
  "Creates": {
      "ScheduleActions": [
          {
            "ScheduleActionStartSettings": {
              "FollowModeScheduleActionStartSettings": {
                "FollowPoint": "END",
                "ReferenceActionName": "action-ad-002"
              }
            },
            "ActionName": "action-ad-003",
              "ScheduleActionSettings": {
                 "InputSwitchSettings": {
                    "InputAttachmentNameReference": "zel-cafe",
                      "InputClippingSettings": {
                          "InputTimecodeSource": "ZEROBASED",
               "StopTimecode":{
                 "Timecode": "00:00:30:11",
                 "LastFrameClippingBehavior": "INCLUDE_LAST_FRAME"
       }
      }
     }
    }
   }
  ]
 }
}

切换到具有即时启动时间的动态输入的示例

此请求示例是立即切换到动态文件输入。切换操作称为 action-unscheduled-standby，它会切换到连接到名为 dynamic-unscheduled-standby 的输入附件的输入。对于这种用于动态输入的用法，要使用的文件是 oceanwaves.mp4。

{
  "ChannelId": "999999",
  "Creates": {
    "ScheduleActions": [
      {
        "ScheduleActionStartSettings": 
          {
          "ImmediateModeScheduleActionStartSettings": {
          }
         },
       "ActionName": "action-unscheduled-slate",
        "ScheduleActionSettings": {
          "InputSwitchSettings": {
            "InputAttachmentNameReference": "slate",
            "UrlPath":[
              "main/oceanwaves.mp4",
              "redundant/oceanwaves.mp4"]
     }
    }
   }
  ]
 }
}
