Ensure the rendering pipeline writes to a back-buffer while the viewerframe reads from a front-buffer. Excessive Buffer Queue

Video streaming demands a continuous, uninterrupted flow of data. If you are viewing a high-definition IP camera over a weak Wi-Fi connection, packet loss occurs. When the viewerframe misses critical structural data (like video keyframes), it cannot render the subsequent frames, triggering an automatic refresh cycle to find the next available keyframe. 2. Browser Cache and Memory Leaks

Now go forth and refresh with confidence!

The viewerframe holds a queue (usually 1 to 30 frames). A refresh issues a flush() command to this queue. This erases any corrupt, partial, or delayed frames. If a frame was halfway through decoding when the refresh hit, that process is terminated.

You might wonder: why can’t the viewerframe just instantly switch modes without a dedicated refresh operation? The answer lies in the complexity of modern media pipelines.
