Protocol

Gradio endpoint

• API name: /process_single
• Audio input parameter: audio_file
• Video input parameter: video_file
• Output component: single gr.Video

The function returns a video object compatible with Gradio client responses:

{
  "video": "D:/path/to/result.mp4",
  "subtitles": null
}

Notes

The upstream desktop app reads result["video"] from scripts/digital_human_process.py, so this service intentionally exposes one video output instead of multiple outputs. Adding extra Gradio outputs would change client.predict into a tuple and break compatibility.
