About

Upstream upgraded from Farsight 0.1 to Farsight 0.2

Farsight is a library that manages codec negotiation in telepathy calls.

Farsight 0.1 is built against GStreamer0.10 Farsight 0.2 is built against GStreamer1.0

Farsight 0.1 is old and broken.

In order for us to use Farsight 0.2 we need GStreamer1.0 which means we need QtGStreamer 1.0.

QtGStreamer 1.0 had the annoying problem of not existing. Diane has ported it \o/

Building

You will need at least Qt Gstreamer 1.2. If it's not available for your distribution you can obtain it from http://cgit.freedesktop.org/gstreamer/qt-gstreamer/ If you need to build it you probably should use the example cmake command line below.

You need at least farstream 0.2.3, telepathy-farstream 0.6 and telepathy-qt 0.9.5 

git clone http://cgit.freedesktop.org/gstreamer/qt-gstreamer
cd qt-gstreamer
mkdir build
cd build
cmake -DQTGSTREAMER_CODEGEN=ON -DQTGSTREAMER_TESTS=ON ..
make

As of 2015 Mar 18, ktp-call-ui (normal KDE repo) master contains the KDE4 version. A Plasma 5 version one should be done soon.

Checking you've done it right

Run 

ldd /opt/kde4/lib/kde4/libexec/ktp-call-ui | grep -i gstre

and make sure everything is at 1.0.

If you see a 0.10 version of gstreamer anywhere, something went wrong.

Runtime Dependencies

The set of available codecs depends on what gstreamer 1.0+ components you have installed. gstreamer1.0-plugins-good should give you enough for audio.

However if you want to do video chats with Jitsi you'll need H.264 support, that is probably available in gstreamer-1.0 libav.

Troubleshooting

SIP and Jingle are complex protocols and the software stack involved in making this work is fairly complex, so things are likely to go wrong.

ktp-call-ui is interacting with telepathy and farstream. Farstream is a set of plugins for gstreamer that provides support for RTP channels and codec negotiation. Somehow it calls libnice to do the NAT traversal.

You can watch ktp-call-ui interact with telepathy and the SIP or XMPP connection manager using ktp-debugger.

I've found you can do 

export GST_DEBUG=fsrtpconference_disco:5,fsrtpconference_nego:5
${KDELIB}kde4/libexec//ktp-call-ui --persist

To see some of the underlying negotiation being done by farstream. (5 is DEBUG level).

There can also be issues trying to negotiate with SIP servers, to debug your SIP connection, turn off your sip accounts in the KDE telepathy account list, and then do the following in a terminal 

export TPORT_LOG=1
export TPORT_DUMP=/tmp/sip.log
export RAKIA_DEBUG=all
 /usr/lib/telepathy/telepathy-rakia

Once you reactivate the SIP account, the SIP protocol messages should be then written to /tmp/sip.log.
