when you encounter MP4 embedding video tag, the video will be played normally, but the video will change color
code as follows:
<video id="video" loop="loop" controls="controls" preload="auto" poster="upload/mp4/videobg.jpg">
<source src="upload/mp4/index.mp4" type="video/mp4" />
</video>
Video discoloration some computers can and some don"t. It feels like there should be a problem with the mp4 source file. This problem will not occur because other mp4 files have been replaced.
the effect is shown in figure
