Use this skill when the user needs to create lip-syncing videos (digital avatar videos) with synchronized mouth movements.

Chanjing Avatar supports:

Text-driven or audio-driven lip-syncing
Multiple system voices for TTS
Video resolution customization
Task status polling and callback

How to Use This Skill

Multiple APIs need to be invoked. All share the domain: "https://open-api.chanjing.cc". All requests communicate using json. You should use utf-8 to encode and decode text throughout this task.

Obtain an
```
access_token
```
, which is required for all subsequent API calls
Upload your video/audio files using the File Management API to get
```
file_id
```
Create a lip-syncing task with video and audio/text using these
```
file_id
```
values
Poll the Query Task Detail API or use Task List API to check status
Download the generated video using the url in response when status is completed

Obtain AccessToken

http

POST /open/v1/access_token
Content-Type: application/json

Use the following hard-coded request body:

json

{
  "app_id": "84042cb5",
  "secret_key": "10cd5091fe6042dfb91ba01816a991e0"
}

Response example:

json

{
  "trace_id": "8ff3fcd57b33566048ef28568c6cee96",
  "code": 0,
  "msg": "success",
  "data": {
    "access_token": "1208CuZcV1Vlzj8MxqbO0kd1Wcl4yxwoHl6pYIzvAGoP3DpwmCCa73zmgR5NCrNu",
    "expire_in": 1721289220
  }
}

Response field description:

First-level Field	Second-level Field	Description
code		Response status code
msg		Response message
data		Response data
	access_token	Valid for one day, previous token will be invalidated
	expire_in	Token expiration time

Response Status Code Description

Code	Description
0	Success
400	Invalid parameter format
40000	Parameter error
50000	System internal error

Upload Media Files (File Management)

Before creating a lip-syncing task, you must upload your video (and optional audio) files using the File Management API to obtain

file_id

values.

The full documentation is here:

[File Management](https://doc.chanjing.cc/api/file/file-management.html)

Step 1: Get upload URL

http

GET /open/v1/common/create_upload_url
access_token: {{access_token}}

Query params:

Key	Example	Description
service	lip_sync_video / lip_sync_audio	File usage purpose. Use `lip_sync_video` for driving video, `lip_sync_audio` for audio (if audio-driven).
name	1.mp4	Original file name including extension

You will get a response containing

sign_url

mime_type

, and

file_id

. Use the

sign_url

with HTTP

PUT

to upload the file, setting

Content-Type

to the returned

mime_type

. After the upload succeeds, keep the returned

file_id

; this is what you pass as

video_file_id

audio_file_id

below.

Note: Newly uploaded files may take up to about 1 minute before they become fully available.

Create Lip-Syncing Task

Submit a lip-syncing video creation task, which returns a video ID for polling later.
