Error in configure step

Hi,

Thanks for developing the tool! I'm getting an issue in the configure step while running on the JS16 dataset

14:51:48 -I- Reading video information from file
14:52:02 -I- opening video file JS16/videos//1_6/JS16_1.mp4
Index exceeds the number of array elements (1).

Could you please help me with this?

Hey, thanks for trying anTraX!

It seems you have some issue with ffmpeg. Can you give me some information on your operating system version?

If you happen to run on Linux, a common issue is a version mismatch in the libstdc++.so.6 library between matlab and ffmpeg. Try preloading the system library before calling anTraX, in the following way:

export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6
antrax <antrax command>

If it works, I'll show you how to permanently fix the issue.

Awesome, that worked! Yes, please let me know how to fix this permanently.

Great!

To permanently resolve the issue, just remove the matlab version of the library.

For MCR:

sudo mv /usr/local/MATLAB/MATLAB_Runtime/v96/sys/os/glnxa64/libstdc++.so.6 /usr/local/MATLAB/MATLAB_Runtime/v96/sys/os/glnxa64/libstdc++.so.6.orig

For licensed matlab:

sudo mv /usr/local/MATLAB/R2019a/sys/os/glnxa64/libstdc++.so.6 /usr/local/MATLAB/R2019a/sys/os/glnxa64/libstdc++.so.6.orig

Alternatively, if you don't want to mess with matlab's files, define an alias in your bash profile:

alias antrax="LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 antrax"

Super, thanks for the tips!
