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.

Usually, when you run apt upgrade, the system version software will be erased. The custom tools won't work right.
