Use Chanjing Avatar API for lip-syncing video generation (upload audio/video, create tasks, poll results).
npx skills add chanjing-ai/chan-skills --skill chanjing-avatar
调用蝉镜 Avatar Open API：上传音视频素材、创建对口型任务、轮询与获取结果链接。脚本为 Python HTTP/上传客户端，不依赖 ffmpeg/ffprobe。
scripts/*.pymanifest.yaml（environment 段）及本文permissions、clientPermissions、agentPolicy：manifest.yamlclawhub run chanjing-avatarpython skills/chanjing-avatar/scripts/create_task.py …（流程见正文 How to Use）主凭据、上传/下载边界、浏览器引导等：以 manifest.yaml 为准。本篇 How to Use 起为 API 步骤说明。
Use this skill when the user needs to create lip-syncing videos (digital avatar videos) with synchronized mouth movements.
Chanjing Avatar supports:
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。凭据与审稿对表见 manifest.yaml。
详见 manifest.yaml 中 credentials 与 clientPermissions（含本地上传、结果 URL、浏览器行为；合规见顶层 permissions）。
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.
access_token, which is required for all subsequent API callsfile_idfile_id values从 ~/.chanjing/credentials.json 读取 app_id 和 secret_key，若无有效 Token 则调用：
请求体（使用本地配置的 app_id、secret_key）：

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

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。
| 脚本 | 说明 |
|---|---|
get_upload_url.py | 获取上传链接，输出 sign_url、mime_type、file_id |
upload_file.py | 上传本地文件，轮询 file_detail 直到就绪后输出 file_id |
create_task.py | 创建对口型任务（TTS 或音频驱动），输出视频任务 id |
poll_task.py | 轮询任务直到完成，输出 video_url |
示例（在项目根或 skill 目录下执行）：
音频驱动时：先上传音频得到 audio_file_id，再 create_task.py --video-file-id <id> --audio-file-id <audio_file_id>。
| Code | Description |
