Cisco Webex stores its video recordings as ARF files with extension
.arf. I wanted to play such recordings on Linux.
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.
$ cd nbr2_mp4 ./nbr2mp4 file.arf
This did not output any MP4 file.
$ ./nbr_play file.arf nbr_play: error while loading shared libraries: libgtk-x11-2.0.so.0: wrong ELF class: ELFCLASS64
