ROC-RK3588S-PC mp4 playing problem

Rustam

Hi! I am beginner in embedded.
I have ROC-RK3588S-PC. I have two questions:

1) I installed the official image ROC-RK3588S-PC-EXT_Ubuntu20.04-Gnome-r30028_v1.1.1b_230914 there.
After that, I play the file test.mp4 (from firefly@firefly:/usr/local$ ) using Parole Media Player and everything works well.
Next I do
sudo apt update
sudo apt upgrade
After this, mp4 files will not play.

P.S. the same behavior if I install the image ROC-RK3588S-PC_Ubuntu20.04-Gnome-r30028_v1.1.1b_230914

2) How are the two images (ROC-RK3588S-PC-EXT and ROC-RK3588S-PC) different?

Since it is a customized system, apt upgrade is not supported.
After executing apt upgrade, the system version software will be overwritten, causing the customized software to not work properly.
