Some MP4 won't play on my Xiaomi 13 Ultra

Unable to play MP4 files on your Xiaomi 13 Ultra? Your MP4 files probably contain video or audio codec that your device doesn’t support. If that’s the case, you will need to convert them first. This guide explains how to do this in detail.

“Hi, any ideas why my Xiaomi 13 Ultra doesn't play MP4 videos. I've copied several MP4 clips onto my SD card. It turns up in the media player app. But when I go to play it a popup message saying something like ‘this video cannot be played’. Strangely I earlier put an AVI video onto the same SD card. I can play this AVI video fine in the same video player app. MP4 should be playable on Xiaomi 13 Ultra. Why did this happen? Is there anything I can do to solve the issue? Thanks for any help.”
