Viewerframe Mode Refresh Updated |link|
Different environments handle the viewerframe refresh cycle in distinct ways. Here is how to approach updates across popular ecosystems: Web & UI Frameworks (React, Vue, Web Components)
The term is most widely known today as part of a common search string— inurl:"ViewerFrame? Mode=Refresh"
Ensure that your custom editor scripts have ExecuteAlways or ExecuteInEditMode enabled. Without this, the viewerframe will only refresh during active gameplay loops, remaining static while editing.
Today, streaming video is delivered via complex protocols like HLS or WebRTC. In contrast, the Refresh mode of these early cameras used a much simpler mechanism. When a browser requested a URL with Mode=Refresh , the camera's server would respond with a standard HTML page. Embedded within that page was a standard <IMG> tag, the HTML element used to display images. viewerframe mode refresh updated
A high-performance canvas (often WebGL, WebGPU, or Canvas2D) dedicated entirely to drawing shapes, models, or data points.
For scenarios where a slight latency (1 to 3 seconds) is acceptable, Low-Latency HLS breaks the video stream into tiny, sequential file segments. This allows standard media players to handle the refresh logic natively, leveraging hardware acceleration for a much smoother user experience.

A typical transaction resulting in this string of events looks like this:
The old frame buffer was not cleared properly. You are seeing a "ghost" of the previous mode superimposed on the new mode. Solution: Toggle full-screen mode off and on (Alt+Enter). This forces a hard reset of the viewerframe pipeline.
function updateViewerFrame() const frame = document.getElementById('liveViewerFrame'); const timestamp = new Date().getTime(); // Append the updated timestamp to force a true network refresh frame.src = `/live/viewerframe?mode=refresh&updated=$timestamp`; setInterval(updateViewerFrame, 40); // Refreshes approximately 25 times per second Use code with caution. 3. Inspect Network Protocols and CORS Settings When a browser requested a URL with Mode=Refresh
function onModeChange(newMode) viewerFrame.mode = newMode; if (newMode === 'preview') refreshViewerFrame(); // Re-fetch latest saved content
Where the live video feed is contained in a ViewerFrame .
Viewerframe mode refers to a specific operational state within an application or embedded system where a dedicated frame or canvas is allocated strictly for rendering live visual data. This mode is commonly found in:
The recent updates to ViewerFrame Mode, often referred to as a , focus on mitigating common issues found in older rendering mechanisms. These improvements are critical for several reasons: 1. Enhanced Real-Time Accuracy
