 Empathy supports audio+video calls on XMPP. I successfully tested between
 two gmail accounts connected with two Empathy 2.28 clients, and was able
 to have working audio+video.

 However, if Empathy tries to initiate such a call with Pidgin 2.6.2,
 Pidgin simply freezes. Not sure it's the same problems as other bugs I
 have seen when searching in this bug tracker.

Comment:

 Is pidgin consuming CPU when frozen or not?

 When pidgin freezes, please attach gdb to the process (something like "{{{
 gdb -p $(pidof pidgin) }}}" ) and get a backtrace when it's frozen.

 If pidgin ''is'' consuming CPU, also attach strace for a few seconds
 (something like "{{{ strace -p $(pidof pidgin) 2> strace.log }}}" )

Comment:

 No, it is not consuming CPU, and strace only gives 2 lines:
 Process 9148 attached - interrupt to quit
 futex(0x8eff40c, FUTEX_WAIT_PRIVATE, 2, NULL <unfinished ...>

 So anyway, I ran gdb and entered "bt full", I got a trace. Attaching it to
 this bug report..

Comment(by kiddo):

 Note that the computer where pidgin is running does not actually have a
 "webcam" per se, it is a TV tuner that is seen by v4l2 automatically (from
 what I can see in gstreamer-properties). Empathy doesn't seem to have a
 problem with it.

Comment(by kiddo):

 Setting gstreamer-properties to use the "test pattern" instead of v4l2 as
 an input video device allows the call to work. I guess we pinpointed the
 problem :)

Comment(by Zajec):

 Hm, I've installed

 zypper in gstreamer-0_10-plugins-good-extra gstreamer-0_10-schroedinger
 gstreamer-utils

 and it seems to somehow fix my issues. So I guess this freeze happens when
 handling some lack of some tool/library/sth.
