Research direction

First, review the JiaoZiVideoPlayer source code to understand how it manages screen on wakelock settings. Look for any logic that prevents the screen from turning off after video playback completes, especially if a custom lock screen timeout is set. Compare with YouTube's behavior, which likely releases the wakelock upon video end. Check if there is an existing issue or PR addressing this. Also, comment on the issue to ask the user for device details and exact steps to reproduce, as the problem may be device specific.
