call application libjingle, user automatically removed from roster. why?

Question

Okay, Tried running the compiled "call" program in libjingle-0.6.14, on 2 laptops with ubuntu 11.10,

When i log in from the first laptop, and logged in again (with different account) from the other lappy.. The user coming online is immediately removed from roster and im left with no one to call...

Here is the Output..

Removing from roster: smithtejesh@gmail.com/callAB04C4D8

smithtejesh@gmail.com is REMOVED from roster..automatically... what could be wrong here?

Answer 1

It is likely that the arguments for calling the "call" example are incomplete. The example, without modification, that ships with the libjingle source does not capture video/audio from the computer's hardware. It will play rtp dump files that contain audio/video. The source files do come with sample rtp dump files that can be used to play audio/video to a browser client, or can be "transfered" to another "call" example client and saved locally to a rtcp dump file on the second client.

The proper way to use the call example program is along the lines of (if on linux):

./call --videoinput ./test.rtpdump --voiceinput ./voice.rtpdump --videooutput ./vidoutput.rtpdump --voiceoutput ./voioutput.rtpdump

There are a few issues on the libjingle Google code website that talk about this, I am struggling to find them at the moment. If I do, I will edit this post or add a comment with the links.
