Why can’t I play MP4 files on my Xiaomi Redmi Note 12R?

Came upon incompatibility problems playing MP4 videos on Xiaomi Redmi Note 12R? Due to codec issues, some MP4 files will not play on Xiaomi Redmi Note 12R. To be able to play these MP4 files, you will need to convert them first.

“Hi, any ideas why my Xiaomi Redmi Note 12R 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 Redmi Note 12R. Why did this happen? Is there anything I can do to solve the issue? Thanks for any help.”
