==The plan==
{{:KTp/Header}}
 
* The current code is wrong by design, needs to be replaced.
 
* Build a simple Qt library that exports the whole call application logic with a QML-izable interface, using QtGStreamer/farsight/farsight utils/telepathy-qt4.
 
* Build a GUI that possibly consists of a standard KXmlGuiWindow that embeds a QDeclarativeView, which implements the call GUI.
 
===Blockers===
 
* Needs telepathy-qt4 to export interfaces for the Call spec.
** tp-qt4-yell exports them now. will soon be merged to tp-qt4.
* Needs a QML video widget in QtGStreamer.
** this is work in progress.
** we need it if and only if we build the interface using QML.

telepathy-qt-yell provides the Tpy::CallChannel class, which wraps the Channel.Type.Call d-bus object. From this object, we create a TfChannel (provided by tp-farstream) and we wrap it in a QTf::Channel object (provided by libqtf inside the call-ui repository; this is qt-gstreamer based bindings for tp-farstream). This TfChannel object does all the internal communication with the CM and constructs some GStreamer bin (using farsight2/farstream internally) that will do all the streaming. On this bin, we connect our GStreamer sources and sinks using the QtGStreamer API.
== Other Troubleshooting ==
 
If you have farsight installed, it won't work. Remove it.
 
Farstream has to be installed to a location detectable by gstreamer (in my case /usr/)
 
Start the call-ui manually with --debug --persist to get helpful info.

Other Troubleshooting

If you have farsight installed, it won't work. Remove it.

Farstream has to be installed to a location detectable by gstreamer (in my case /usr/)

Start the call-ui manually with --debug --persist to get helpful info.
