SGLang Diffusion Realtime WebUI

Standalone browser demo for /v1/realtime_video/generate.

Open index.html directly in a browser, point it at an SGLang Diffusion server, and generate. The app sends msgpack init / event messages and renders lossless raw RGB frame batches on a canvas.

The first version is intentionally static: no npm install, no build step, and no server-side dependencies. Presets are UI-side templates for prompt, LingBot example images, album artwork references, and session parameters. The default preset preloads a reference image so the demo can be tested without a file upload.

By default, Continuous session is enabled for long-running camera control. Keyboard and pointer controls send state transitions instead of scripted preset actions. The telemetry Chunk wait measures request-to-chunk arrival time, not client-side RGB decode time. Continuous playback adapts to the measured chunk production rate so the canvas does not play a chunk at target FPS and then sit on the last frame while waiting for the next chunk.

The interface shape follows camera-control-first video playgrounds such as Reactor LingBot: reference image, scene prompt, enhancement, clip controls, move/look camera controls, recordings history, and model telemetry.
