.mp4 does not support memory mapping

Thank you for providing such a convenient tool. After I finished installing all the required environments and tried to run the script ./bin/FeatureExtraction -verbose -f "../samples/default.wmv", the following error occurred:
Attempting to read from file:../samples/default.wmv
../samples/default.wmv does not support memory mapping
Failed to open the video file at location: ../samples/default.wmv

My linux is Centos.
