[jitsi-users] no webcam video from sender


#1

Hi,

I am Using jitsi 1.0-beta1-nightly.build.3820 on ubuntu 10.10/maverick.

Two jitsi clients connected to the same server. The jitsi client running on maverick does not show the webcam video, the other jitsi client running on natty does show the webcam video of the maverick-jitsi. For audio both clients work as it should. The webcam on both jitsis are working and recognised by jitsi. Only the jitsi/maverick has trouble showing the video imaged in jitsi. Using guvcview all works well in maverick.

What to add/update/change on ubuntu maverick to get video working?

on maverick i have
libstdc++6 -> 4.5.1-7ubuntu2
libstdc++6-4.4-dev -> 4.4.4-14ubuntu5

Jisti on maverick complains about som lib missing, i assume that is where the cause is:

Main loop terminated.
java.lang.UnsatisfiedLinkError: /usr/lib/jitsi/lib/native/libglobalshortcut.so: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by /usr/lib/jitsi/lib/native/libglobalshortcut.so)

Hi,
I want only to report my experience.

I've got the same problem with libglobalshortcut.so (using openSUSE 10.4). It appears that it was linked with a new version of libstdc++ (higher than 4.5.1) that is not available on every distribution. Maybe developers should think about compiling with an older libstdc++ version.

Anyway it seems that this problem doesn't interfere with the rest of Jitsi. In fact, I've been able to do (video)call in this situation.

Regards,
Daniel

libstdc++6-4.4-dev -> 4.4.4-14ubuntu5

Do you use SIP or XMPP for the video call ?
Can you send us your log as well (see http://jitsi.org/index.php/Documentation/FAQ#logs)

Jisti on maverick complains about som lib missing, i assume that is where the cause is:

As Daniel Zuchetto said, it is due to compilation with recent libstdc++. We will recompile this library with an older installation shortly.
