Hello Xu Ji,

Is this problem still present? I would recommend looking at the default kernel configuration files as sometimes there are additional dependencies to the drivers.

If you modified the media driver then check with the manufacturer if there are additional dependencies and make sure that the required libraries are also installed.

I hope this helps.

Regards,
