Question

How does the ckplayer video player plug-in turn on and off the light? Asking all the gods for help

Answer 1

ckplayer’s compatibility is too poor

Answer 2

I haven’t used it before. Generally, the special effects of turning on and off the lights are written separately. How could someone else write a video plug-in and also include a web page to turn on and off the lights. . .
Simply try writing a black layer mask. When the light is turned off, the layer will be displayed. You just need to ensure that the z-index of the video is above the layer
