Did you find any example. I'm interested in record just the audio between 2 videoconference participants?
Answer a bit late but for those who stumbled upon this later.
There is this excellent description
With a link to a working demo
For which the source code is also provided.
We just developed such an application. You can see it at
The main difference from sample application is:
1. Conference: multiple videos/users
2. Server-less: does not need a server for peerid exchange
3. Smart bandwidth usage: There can be hundreds of users in a conference (aka room) and your bandwidth utilization is only as many videos as you are watching.
4. Single Upload Video Stream: If 100 people are watching you,you only transmit video once (sample application does not do this, if 100 people are watching your video, you need to upload it 100 times)
Currently it is targeted at consumers and hence does not have file sharing and whiteboard in it yet. Of course it can be added if needed. If you are interested, send me an email at firstname.lastname@example.org
