Problem

Cisco Webex stores its video recordings as ARF files with extension .arf. I wanted to play such recordings on Linux.

Solution

No solution is working right now

There is a converter to MP4 provided by Webex here. I downloaded the nbr2mp4.tar file and unpacked it.

• I ran the nbr2mp4.sh script to unzip the files.

$ cd nbr2_mp4
./nbr2mp4 file.arf

This did not output any MP4 file.

• The NBR player too did not work:

$ ./nbr_play file.arf
nbr_play: error while loading shared libraries: libgtk-x11-2.0.so.0: wrong ELF class: ELFCLASS64
