Web Page (Chromium, Windows)

Web Page (Chromium, Windows) input properties for Script Engine. Renders a live web page as a video and audio source using a Windows-native Chromium-based browser (CefSharp). Point it at any HTTP/HTTPS URL — graphics overlays, scoreboards, dashboards, social-media feeds, or any other browser-renderable content — and Composer captures the page as a layer it can mix with the rest of the project. Includes auto-start on load, automatic reload on error, configurable resolution, scroll-bar control, and optional forwarding of the page's JavaScript console output to the log. Captures both video and audio from the page. Windows-only; for Linux or other platforms, use the cross-platform Web Page input instead.

Property	Type	Access	Description
`ShowAdvancedOptions`	`bool`	`get/set`	Show or hide the input's advanced settings in the editor UI. [default=false].
`WebPageRendererUrl`	`string`	`get/set`	HTTP or HTTPS URL of the web page to render. Set to any standard web URL. Changing this from a script lets you swap the rendered page at runtime — handy for cycling through dashboards, scoreboards, or status pages. Set to an empty string to clear the page.
`ReloadCommand`	`Command`	`get`	Reload the current page.
`BrowserLoadState`	`BrowserLoadState`	`get`	Current browser state (read-only). Reflects whether the browser is idle, loading, or actively rendering. Driven indirectly by `StartCommand`, `StopCommand`, `ReloadCommand`, and the `AutoStart` behaviour at load time. Read this from a script to decide whether the page is live.
`Width`	`int`	`get/set`	Width of the rendered page, in pixels. [min=32, max=4096, default=1024]. Acts like the browser's viewport width. Pages adapt their layout to this size, so set it to match how you want the page to render.
`Height`	`int`	`get/set`	Height of the rendered page, in pixels. [min=32, max=4096, default=360]. Acts like the browser's viewport height. Pages adapt their layout to this size, so set it to match how you want the page to render.
`ScrollBarXPos`	`int`	`get/set`	Horizontal scroll position of the page, in pixels. [min=0, max=50000, default=0]. Scrolls the rendered page left or right to a specific position. Useful for showing part of a wide page that wouldn't otherwise fit. Setting this calls `window.scrollTo` inside the page.
`ScrollBarYPos`	`int`	`get/set`	Vertical scroll position of the page, in pixels. [min=0, max=50000, default=0]. Scrolls the rendered page up or down to a specific position. Useful for revealing content lower on the page or for animating a scroll over time from a script. Setting this calls `window.scrollTo` inside the page.
`StartCommand`	`Command`	`get`	Start loading the URL and rendering the page.
`StopCommand`	`Command`	`get`	Stop rendering the page.
`AutoStart`	`bool`	`get/set`	Whether the input starts rendering as soon as the project loads. [default=false]. When true, the input invokes its start logic immediately on load (equivalent to running `StartCommand`). Disable to require an explicit start, useful when the page should only come live on operator action or via a script trigger.
`AutoReloadPageOnError`	`bool`	`get/set`	Whether the page is automatically reloaded after a load error. [default=false]. When true, a failed load is retried automatically. Useful when the source server may be temporarily unavailable. Disable for one-shot loads that should not retry.
`EnableConsoleLogging`	`bool`	`get/set`	Whether messages logged by the page's JavaScript are written to Composer's log. [default=false]. Useful for debugging custom HTML overlays — `console.log` calls from the page show up alongside Composer's other log messages.
`NumReloadsPerformed`	`int`	`get`	Total number of times the page has been reloaded since the input was started (read-only, debug). Driven by both manual `ReloadCommand` invocations and automatic reloads triggered by `AutoReloadPageOnError`.
`LastCefCallbackMessageType`	`CefCallbackMessageType`	`get`	Result of the most recent page load finalizer callback (read-only, debug). Internal diagnostic value reflecting how the most recent page load ended.
`VideoQueueSize`	`int`	`get`	Number of rendered frames currently buffered ahead of playback (read-only, debug). Should sit close to zero on a healthy system. A growing queue means the rest of the pipeline is consuming frames more slowly than the browser is producing them.
`PageRenderPerformance`	`string`	`get`	Recent per-frame rendering time, formatted as a millisecond string (read-only). Useful while monitoring how heavy the page is to render. Pages with complex animations or video elements take longer to render than static pages.
`RenderStart`	`DateTime`	`get`	Local timestamp of when the input most recently started rendering (read-only, debug).
`FramesRendered`	`long`	`get`	Total number of frames rendered from the page since the input was started (read-only, debug). Should grow steadily during healthy rendering. A counter that stops moving while the browser is running indicates the page itself has stalled.
`Fps`	`int`	`get`	Recent rendering frame rate, in frames per second (read-only, debug). Reflects how often the browser is producing new frames. Pages that don't animate may report a low or zero frame rate even while loaded successfully.
`AudioFramesReceived`	`int`	`get`	Total number of audio frames received from the page since the input was started (read-only, debug). Increments only when the page actually produces audio. Useful for confirming an expected audio source is delivering audio.
`AudioSamplesInQueue`	`int`	`get`	Number of audio samples currently buffered ahead of playback (read-only, debug). A small steady value is normal during continuous audio. A growing buffer suggests audio is arriving faster than Composer is consuming it.
