Description Nicolas da Luz Duque 2008-01-17 15:16:09 UTC

I used it for testing purposes, launching telepathy-stream-engine with these lines:

iceman@Rakuen:~ $ export FS_VIDEO_SRC="videotestsrc" //because I don't have a webcam
iceman@Rakuen:~ $ export STREAM_ENGINE_PERSIST=1
iceman@Rakuen:~ $ gdb telepathy-stream-engine

Then, I launched:

iceman@Rakuen:~ $ GABBLE_DEBUG=all /usr/lib/telepathy/telepathy-gabble 

And finally: 

python /usr/share/doc/python-telepathy/examples/call.py /home/iceman/gabble-account <my friend's jabber address>

He picked up the conversation, and after a short while, stream-engine crashed:

Voilà! I sould also report that, before it crashed, I was hearing my friend just fine, while he couldn't comprehend a single word of what I was telling him, but I guess that's another bug.

Comment 1 Nicolas da Luz Duque 2008-01-17 15:26:18 UTC

Ok I forgot to tell I'm using version  

* 0.12.5 of gstreamer0.10-plugins-farsight
* 0.1.25 of libfarsight
* 0.7.0  of telepathy-gabble
* 0.4.0  of telepathy-stream-engine

If you need more info, feel free to ask.

Comment 2 Olivier Crête 2008-01-17 15:26:30 UTC

From the log, it seems that the call was ended by the connection manager (that means either by you or by the remote end). The crash is in the teardown procedure, but without debugging symbols, its impossible to know whats going on.
