Viewerframe Mode Refresh Updated

It allows browsers that do not natively support MJPEG (a common issue in older browsers) to view a live camera feed by rapidly refreshing individual JPEG images.

User switches from mode A to mode B, but the ViewerFrame shows mode A’s content for 2-3 seconds.

Solution: Implement a rendering lock or cancel previous animation frames using cancelAnimationFrame() before starting refreshUpdated() . viewerframe mode refresh updated

User Action / External Event ↓ Mode Validation (e.g., can we refresh in current mode?) ↓ Data Fetch / Recalculation ↓ Frame Buffer Preparation ↓ Refresh Execution (sync or async) ↓ Post-Refresh Hooks (e.g., stats logging, callback triggers) Solution: Implement a rendering lock or cancel previous

If you could provide more context or clarify the specific software or application you're referring to, I could offer a more targeted and detailed explanation.

Like iDRAC or ILO, which use frames to redirect a server’s console to your browser.
