What is causing the error and what are the steps for corrective action? Error message:
MATLAB has a later version of libstdc++:
  • attempts to use the older libstdc++ version prevents MATLAB from starting
alias matlab='LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.21 /usr/local/MATLAB/R2018b/bin/matlab -desktop'
  • explicit MATLAB invocation (via alias below) with MATLAB's libstdc++ does not resolve error:
alias matlab='LD_PRELOAD=/usr/local/MATLAB/R2018b/sys/os/glnxa64/libstdc++.so.6.0.22 /usr/local/MATLAB/R2018b/bin/matlab -desktop'
R2018b is installed on Ubuntu 16.04. GStreamer install command:
apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools
GStreamer plays videos from command line:
gst-launch-1.0 playbin uri=file:////home/user/MATLAB_DATA/OverheadCamDetect/OverheadCam.mp4
MATLAB has the newer version of the libstdc++ versions available:
ls -l /usr/local/MATLAB/R2018b/sys/os/glnxa64/libstdc++.so.6.0.22 #V22: MATLAB
ls -l /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.21 #V21: Ubuntu_16.04
Because MATLAB is packaged with a later version of stdlibc++, explicitly call MATLAB packaged stdlibc++ (same error results)
alias matlab='LD_PRELOAD=/usr/local/MATLAB/R2018b/sys/os/glnxa64/libstdc++.so.6.0.22 /usr/local/MATLAB/R2018b/bin/matlab -desktop'
OTHER UNSUCCESSFUL APPROACHES
Redirecting the link to the older libstdc++ prevents MATLAB from starting:
cd /usr/local/MATLAB/R2018b/sys/os/glnxa64
sudo unlink /usr/local/MATLAB/R2018b/sys/os/glnxa64/libstdc++.so.6 #V22: MATLAB
sudo ln -s /usr/local/MATLAB/R2018b/sys/os/glnxa64/libstdc++.so.6.0.22 libstdc++.so.6
Attempts to rename libstdc++ per Mathworks instructions was NOT successful (MATLAB would not start):
cd /usr/local/MATLAB/R2018b/sys/os/glnxa64
ls -l libstdc++.*
sudo mv libstdc++.so.6 backuplibstdc++.so.6
sudo mv libstdc++.so.6.0.22 backuplibstdc++.so.6.0.22
ls -l ls -l backuplibstdc++.*
% MATLAB fails to boot so restore the files to original condition:
sudo mv backuplibstdc++.so.6.0.22 libstdc++.so.6.0.22
sudo mv backuplibstdc++.so.6 libstdc++.so.6

I have the same issue, i can read .avi without problem, but no .mp4. The output of videoReader.getFileFormats only show .avi and .mj2. with or without gstreamer1.0 (oficial)in Ubuntu 16.04.5 x64. Fresh instalation of Matlab R2018b

I have a solution that work for me in Ubuntu 16.04.5 LTS:
First Uninstall and purge gstreamer1.0 and gstreamer0.1
Compiling from source
  1. Download and compiling orc-0.4.28 (https://gstreamer.freedesktop.org/src/orc/)
  2. Decompress the .xy file. Inside the decompressed directory* $ ./configure* $ make* $ sudo make install
  3. Do the same in point 2 for https://gstreamer.freedesktop.org/src/:
gstreamer/gstreamer1.14.4
gst-plugins-base/gst-plugins-base-1.14.4/
gst-libav/gst-libav-1.14.4/
gst-plugins-good/gst-plugins-good-1.14.4
After this, run matlab from shell $ matlab ... et voila
Please, tellme if this solution work for you.

I've completed these steps, unfortunately the error persists.
Matlab: R2018b
OS: Ubuntu 16.04

I was getting the same gstreamer error on Matlab2018b in Ubuntu 16.04. The following solution worked for me: https://uk.mathworks.com/matlabcentral/answers/294258-hello-i-have-a-problem-with-videoreader-on-matlab-r2016a-with-ubtuntu-lts16-04
