Chanjing Avatar (Lip-Syncing)

When to Use This Skill

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

前置条件：执行本 Skill 前，必须先通过 chanjing-credentials-guard 完成 AK/SK 与 Token 校验。

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.

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

Obtain AccessToken

从 ~/.chanjing/credentials.json 读取 app_id 和 secret_key，若无有效 Token 则调用：

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

请求体（使用本地配置的 app_id、secret_key）：

{
  "app_id": "<从 credentials.json 读取>",
  "secret_key": "<从 credentials.json 读取>"
}

Response example:

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

Response Status Code Description

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

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

Query params:

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 PUT completes, poll the file detail API until the file is ready (do not assume a fixed wait). Keep the returned file_id for video_file_id / audio_file_id below.

Polling: Call GET /open/v1/common/file_detail?id={{file_id}} with access_token until the response data.status indicates success (e.g. status === 2). Only then use the file_id for the create task API.

Create Lip-Syncing Task

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

POST /open/v1/video_lip_sync/create
access_token: {{access_token}}
Content-Type: application/json

Request body example (TTS-driven):

{
  "video_file_id": "e284db4d95de4220afe78132158156b5",

Scripts

本 Skill 提供脚本（skills/chanjing-avatar/scripts/），与 chanjing-credentials-guard 使用同一配置文件（~/.chanjing/credentials.json）获取 Token。

示例（在项目根或 skill 目录下执行）：

# 1. 上传驱动视频，得到 video_file_id
VIDEO_FILE_ID=$(python skills/chanjing-avatar/scripts/upload_file --service lip_sync_video --file ./my_video.mp4)

# 2. 创建 TTS 对口型任务（需先通过 list_common_audio 获取 audio_man_id）
TASK_ID=$(python skills/chanjing-avatar/scripts/create_task \
  --video-file-id "$VIDEO_FILE_ID" \
  --text "君不见黄河之水天上来" \
  --audio-man-id "C-f2429d07554749839849497589199916")

# 3. 轮询直到完成，得到视频下载链接
python skills/chanjing-avatar/scripts/poll_task --id "$TASK_ID"

音频驱动时：先上传音频得到 audio_file_id，再 create_task --video-file-id <id> --audio-file-id <audio_file_id>。
