Wan 2.7 image-to-video

Submit an asynchronous Ali wan2.7-i2v generation task.

This capability uses the top-level media array to represent the upstream input.media protocol.

Implemented official media.type values are first_frame, last_frame, driving_audio, and first_clip.

Supported media combinations in the current project implementation:

• first_frame
• first_frame + driving_audio
• first_frame + last_frame
• first_frame + last_frame + driving_audio
• first_clip
• first_clip + last_frame

prompt is optional for this capability. size supports only 720P and 1080P. seconds supports integer strings from 2 to 15. Official fields negative_prompt, prompt_extend, watermark, and seed are also supported.
