Error using VideoReader/initReader (line 729)

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.

first,

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

then

yum -y --enablerepo=nux-dextop install gstreamer-ffmpeg vlc gstreamer-plugins-ugly gstreamer-plugins-bad gstreamer-plugins-ugly ffmpeg libvdpau mpg123 mplayer mplayer-gui gstreamer-plugins-bad-nonfree gstreamer1-libav gstreamer1-plugins-bad-freeworld gstreamer1-plugins-ugly
