Video not running

i am using lubuntu 21.04 version everything is running fine except video.
In vlc only audio is playing. i have tried with many codec commands but still did not found any solution. kindly do the needful.

Can you maybe tell us a bit more about what kind of video file you’re trying to play? What have you tried exactly? We can’t help unless we know what you’re working with.
