Skip Music Intro

Feature Introduction

Skip music intro capability can automatically identify the time point when the intro ends (singing starts) based on the user's input original music

API Description

Request Method: POST (HTTP)

Request URL: https://api.mediax.tencent.com/job

Request Header: Content-Type: application/json

Request Flow: The API includes 'Create Task' and 'Query Task'. After creating a task, users can actively query the task to know the result, or input a callback address when creating the task, and the task will automatically callback to that address after completion

Get Task Information

There are two ways to get information: active query and passive callback.

Active query has two types of query interfaces based on id category: one is to query based on user-defined id, since the platform cannot guarantee the uniqueness of this id, it returns a Job array (see 1); the other is to query by the id in the response after creating the task (see 2)
Passive callback requires filling in the callback field when creating the task, the platform will send the Job structure to the address specified by callback after the task enters the completion state (COMPLETED/ERROR) (see 3), the platform recommends using passive callback to get task results.

In the skip music intro capability, if the queried task is successful (state=3), the task's Output will carry a smartContentResult structure, in which the skipMusicIntro field stores the end time of the intro in the original music, in seconds.

1. Active Query, Based on User-Defined customId Passed When Creating Task Request Example:

{
  "action": "ListJobs",
  "secretId": "{secretId}",
  "secretKey": "{secretKey}",
  "listJobsRequest": {
    "customId": "{customId}"
  }
}

Response Example:

{
  "requestId": "c9845a99-34e3-4b0f-80f5-f0a2a0ee8896",
  "listJobsResponse": {
    "jobs": [
      {
        "id": "a95e9d74-6602-4405-a3fc-6408a76bcc98",
        "state": 3,
        "customId": "{customId}",
        "callback": "{callback}",
        "timing": {
          "createdAt": "1610513575000",
          "startedAt": "1610513575000",
          "completedAt": "1610513618000"
        },
        "inputs": [{ "url": "{url}" }],
        "outputs": [
          {
            "inputSelectors": [0],
            "smartContentDescriptor": {
              "skipMusicIntro": 2
            },
            "smartContentResult": {
              "skipMusicIntro": "15.3"
            }
          }
        ]
      }
    ],
    "total": 1
  }
}

2. Active Query, Based on id in Response After Creating Task Request Example:

{
  "action": "GetJob",
  "secretId": "{secretId}",
  "secretKey": "{secretKey}",
  "getJobRequest": {
    "id": "{id}"
  }
}

Response Example:

{
  "requestId": "c9845a99-34e3-4b0f-80f5-f0a2a0ee8896",
  "getJobResponse": {
    "job": {
      "id": "a95e9d74-6602-4405-a3fc-6408a76bcc98",
      "state": 3,
      "customId": "{customId}",
      "callback": "{callback}",
      "timing": {
        "createdAt": "1610513575000",
        "startedAt": "1610513575000",
        "completedAt": "1610513618000"
      },
      "inputs": [{ "url": "{url}" }],
      "outputs": [
        {
          "inputSelectors": [0],
          "smartContentDescriptor": {
            "skipMusicIntro": 2
          },
          "smartContentResult": {
            "skipMusicIntro": "15.3"
          }
        }
      ]
    }
  }
}

3. Passive Callback

The entire Job structure of the task that enters the completion state (COMPLETED/ERROR) will be sent to the address corresponding to the callback field specified by the user when creating the task. See the active query example (under getJobResponse) for the Job structure
