reliable p2p video-chat

Hi!

Saying p2p I mean direct (without some kind of account) chat between two workstations each with static IP and opened all needed ports. I have tried plenty pieces of software (linphone, qutecom, jitsi, ekiga, empathy, ...), but have not found acceptable one (direct sip call - like sip:name@1.2.3.4 - doesn't work at all, or segfaults, or memory leak, and so on).

Is anybody more lucky rather I am?

P.S. I don't mean it must be sip client - probably another p2p ways exists.

Re: reliable p2p video-chat

It has to be user friendly ?
If not, you can use the combinaison of: ssh, ncat, mplayer (and may be ffmpeg for screen sharing).
I can't find right now the link to how to do it. But if you are interested you can digg in this sense.

Re: reliable p2p video-chat

Most VoIP software uses UDP to prevent lag (dropped packets can be ignored). mplayer over netcat over ssh will probably lag on any reasonable connection.

Probably script-based way is also acceptable.

I have found this interesting package (it exists in AUR)

http://www.creytiv.com/baresip.html

but have not found any documentation for it yet (searching results in openwrt integration).

I can't help you with SIP things, 'cause they never worked for me, sorry.
I used my proposition (ssh .....) for audio chatting once (and yes there were lags).

Re: reliable p2p video-chat

UDP should work as long as the ISP(s) are not monkeying with traffic to/from "uncommon" ports and of course if port forwarding and firewalls are properly configured. Programs should also allow and respect custom fixed ports configuration.

Some ISPs seem to throttle traffic to/from "uncommon" ports, so much that at times it makes things impossible to work reliably. I guess some ISPs might also block some kinds of traffic altogether to sell their own (usually inferior) version of the same otherwise free service.

Crazy (or maybe not) idea, if you can create a vpn between the machines you want to use and force the chat programs to use that .... it might work ... as long as the ISPs do not throttle it, I have no clue if it will be faster or slower than using ssh (no experience with vpns).

It is possible inside LAN network and it is possible in WAN if you have Asterisk http://www.asterisk.org/ installed, so I have been told.


I know of a software which is does exactly that with audio only.

I Hear U Project http://ihu.sourceforge.net/
CLI and a QT3 interfaces are available.
