MATLAB: Error using VideoReader/initReader (line 729)

centosdeploytoollinuxMATLABvideoreader

I'm using MATLAB 2019a. (Linux)
I use deploytool to convert my mcode to executable file (on ubuntu 16.04).
The file "run_SigFunc.sh" is working well on ubuntu 16.04.
And then I move these file to anaother computer which has CentOS7.6 (No GUI).
When I running this, it has something wrong.
The error information:
Error using VideoReader/initReader (line 729)
Could not read file due to an unexpected error. Reason: Unable to initialize the video properties
Error in audiovideo.internal.IVideoReader (line 148)
Error in VideoReader (line 98)
Error in SigFunc (line 27)
MATLAB:audiovideo:ViedeoReader:Unexpected
Could you please give me some advices for this problem? Thank you all.

I've found the reason.
Lack of audio/video system decoder.

rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm
yum -y install epel-release
