Option A: Local Files (Recommended)

Implementation Notes

• Local files: The skill handles upload automatically. Files are uploaded to OSS and URLs are generated.
• URL input: Image and audio URLs must be publicly accessible (not behind authentication)
• Audio duration: Cannot exceed 3 minutes
• The API is async: You must poll for results
• Poll every 2-3 seconds, with a timeout of ~60 seconds
• Status codes: 0 = pending, 1 = processing, 2 = processing (not failed!), 3 = completed, 4 = timeout
• Uploaded file URLs: Only valid for 1 day (Storage service is free but for AI program support only)

Upload Process Flow

text

Local File → Get Upload Policy → Upload to OSS → Get Public URL → Generate Video

The skill implements this flow automatically when local files are provided:

1. Call get_policy to receive OSS credentials
2. Upload image/audio to OSS
3. Construct public URL from host + key
4. Call DreamAvatar API with the uploaded URLs
5. Poll for video completion
6. Return the final video URL
