I try to get away from well-known proprietary videoconference software
but have no luck... I'll detail my experience with Jitsi, and appreciate
The base situation could hardly be better: I'm a Free Software
developer, both machines (parents' place and me) run Debian Wheezy
(amd64) - slightly mixed package repositories, but both use the same
OpenJDK 7 (IcedTea7 2.1.7) from Wheezy and the latest jitsi package
(2.2.4603.961). The webcam is the same on both machines, a Logitech
C310, working fine in other applications. Both machines are behind NAT,
but I control the Asterisk SIP server in between (and also tried
third-party services like ippi.fr). At some point in the past, I got so
desperate that I even tried setting up an OpenVPN with IPv4 or IPv6,
just to exclude all NAT issues.
The Options - Video - Devices screen shows a good live image! With older
Jitsi versions, I didn't even get that far. Only, as soon as the call
starts, the JVM says goodbye on the receiving side:
# A fatal error has been detected by the Java Runtime Environment:
# SIGSEGV (0xb) at pc=0x00007fd4a13e7a91, pid=17825,

# Java VM: OpenJDK 64-Bit Server VM (22.0-b10 mixed mode linux-amd64

# Problematic frame:

I tried playing around with video codecs, or disabling encryption
support - but it's always the same result: sws_scale in libjnffmpeg.so.
I didn't see an open ticket. Is this a known bug?
Here's the log:
The core dump mentioned in the log did not show up in any file, though.
All the best,
