The main purpose of the Shutdown Decoders feature is to reduce CPU/GPU & memory usage, and it does so by suspending the video element's video decoder when the video element is in background tabs or is invisible even in the foreground tab. The mechanism is that, when a video element is invisible, the original video decoder is replaced with a blank video decoder which only produces white frames that have the right resolution and time information. The original video decoder is released and the | The main purpose of the Shutdown Decoders feature is to reduce CPU/GPU & memory usage, and it does so by suspending the video element's video decoder when the video element is in background tabs or is invisible even in the foreground tab.
