sounds like you need to install the gstreamer tools. on my device so can't search easily for you. but the terminal commands is in one of my healthcheck threads/posts.

ii gstreamer0.10-tools 0.10.25-0maemo2+0m5 Tools for use with GStreamer

I am looking at your post now.

I checked your post that was mentioned above and the source code. Nice starting app.
I see you create an image and save it into the phones memory and then use that image to create a QPixmap and display it on the screen. I am not sure if this is the way how I should implement camera example on QT, as I want to display a continues stream of video until the photo is taken. This is why I think I need to use x_overlay.
However, I would also like to draw on top of the video stream like the native camera app on N900 does.
Any other suggestions?
Cheers,
Klen

This is a totally uninformed opinion, but maybe you should look into Phonon. Its the QT OO front end to gstreamer.
(Using python)

I managed to link the needed libraries. I could not do it automatically using pkg-config instead of manually (i.e. -L/usr/lib/gtk-2.0 -lgtk+-2.0).
I added one line to my QMAKE file, where I add a linker flag and define names of libraries that are needed.
QMAKE_LFLAGS += `pkg-config --libs gtk+-2.0 \
--libs gstreamer-interfaces-0.10
One problem solved, one to go.
I still did not manage to link the pipeline sink to any of QT objects. I am looking into Phonon now. Looks promising. Hope it gets me somewhere.

The documentation for Phonon can be found:
QT Phonon 4.4: http://qt.nokia.com/doc/4.4/phonon-module.html
QT Phonon 4.6: http://qt.nokia.com/doc/qt-maemo-4.6...-overview.html

Found a useful link. It might get there eventually.

I am trying to port Maemo Camera Example to QT and run into problems.
PROBLEM 1: SOLVED
I guess I am getting the:
/home/klen/workplace/maemo/DistanceQT/src/cameraN900.cpp:399: undefined reference to `gst_x_overlay_get_type'
/home/klen/workplace/maemo/DistanceQT/src/cameraN900.cpp:399: undefined reference to `gdk_x11_drawable_get_xid'
/home/klen/workplace/maemo/DistanceQT/src/cameraN900.cpp:399: undefined reference to `gst_x_overlay_set_xwindow_id'
because I am missing libraries. Bellow is my QMAKE FILE:
CFLAGS=-O0 -g
CXXFLAGS=-O0 -g
TEMPLATE = app
TARGET =
DEPENDPATH += .
INCLUDEPATH += .
QMAKE_CLEAN += distanceqt
#Includes
INCLUDEPATH +=. /usr/include/ \
/usr/include/gtk-2.0/ \
/usr/include/gtk-2.0/gtk/ \
/usr/include/gstreamer-0.10/ \
/usr/include/glib-2.0/ \
/usr/include/glib-2.0/glib/ \
/usr/include/glib-2.0/gio/ \
/usr/include/glib-2.0/gobject/ \
/usr/include/cairo/ \
/usr/include/pango-1.0/ \
/usr/include/atk-1.0/ \
/usr/include/libxml2/ \
/usr/include/dbus-1.0/ \
/usr/lib/gtk-2.0/include \
/usr/lib/gstreamer-0.10 \
/usr/lib \
/usr/lib/glib-2.0/include \
/usr/lib/dbus-1.0/include
LIBS += -L/usr/lib/glib-2.0 -lglib-2.0 \
-L/usr/lib/gstreamer-0.10 -lgstreamer-0.10 \
HEADERS += src/appdata.h src/camerafield.h src/cameraN900.h
SOURCES += src/appdata.cpp src/camerafield.cpp src/main.cpp src/cameraN900.cpp
I googled and found out that I should link in gstinterfaces-0.10 and gtk-2.0. If I add these two libraries in the same way as I did the others:
-L/usr/lib/gtk-2.0 -lgtk+-2.0 \
-L/usr/lib/ -lgstinterfaces
I get an error:
cannot find -lgtk+-2.0
cannot find -lgstinterfaces
What should I do to include these tow libraries in my QMAKE file. Do I need to find a workaround by manually updating the make file?
PROBLEM 2: SOLVED
I have a problem linking the gstreamer pipeline sink to any of QT objects. There was a suggestion by mmurfin87 to check Phonon. I am looking into Phonon now. Any other suggestions?
Thanks,
Klen
