ARF i.e Advanced Recording Format is a format recorded by NBR(Network Based Recording).For Ubuntu or other Linux versions currently no player is available which can play .arf files i.e WebEx(Player used to play and convert arf and wrf formats) is not supported on Linux based system or Ubuntu 10.04.That’s why to play arf file only one option is available and that is to convert the arf format to mp4 or swf or other simple formats.So you can use a converter tool “NBR2MP4” to generate mp4(That we can play Using VLC player) file from arf.

Where SOURCE means the name of the arf file which you want to convert and don’t forget to specify pathname if it is in the different directory.MP4-DIRECTORY stands for the output file i.e filename.mp4,it’s name will be same as arf file except the extension of .mp4(Use ./ to generate in the same directory as of input file).In FPS(Frame Per Second) field you can specify between 3 to 10(Default value is 5).The quality of the mp4 file(output file) is directly proportional to the FPS.

e.g rkjha@rkjha-desktop:~/extra_softwares/nbr2_mp4$ ./nbr2mp4 tutorial1.arf ./ 8
Converting /home/rkjha/extra_softwares/nbr2_mp4/tutorial1.arf to /home/rkjha/extra_softwares/nbr2_mp4/./tutorial1.mp4

  1. I untarred & installed nbr2mp4.tar on my Fedora 13 system. Converting ~ 55:00 .arf appeared to be successful. Unfortunately while playing the generated mp4, much of the beginning audio was missing, and the rest never synchronized to the original/real webex presentation.

    1. Confirmed.  I wasn’t getting any output at all on Ubuntu 11.10 (Oneiric).  I let it run for 6 hours, and then killed it.  If anyone can figure out how to get it running in recent Ubuntu, please post!

  2. Ubuntu 12.04.. Left the conversion process to run overnight.. No luck.. I can see that all 4 cores on my computer are still maxing out, meaning some number crunching is still going on, but no output file even after a whole night.. Any ideas anyone?

  3. I’ve been lucky; it was able to convert the arf on Ubuntu 13.04. Only problem is the resulting MP4 doesn’t seek properly (soundtrack seeks, video gets stuck).

    BUT if you don’t mind playing online, Webex IS supported on Firefox 4, and it’s not difficult to install an old version of Firefox for this…

    I’d just like to say a big Linus Torvalds-style ****-you to Cisco for their neglect of other OSs. Yes ****-you Cisco, may you rot in the proprietary crapware hell of your own creation!


  4. WebEx removed the Linux versions of everything. They have tightened their codec up, and are not allowing any OS other than Win/Mac access. The best option is to use RecordMyDesktop for Linux, which is in the Repos for Linux Mint v16, which I use. But, for viewing .arf files, I installed the WebEx viewers in my Windows7 VBox instance.

  5. it shows converting to x.mp4 but no file is generated in the mentioned path
