# 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.
