I have a problem with Qt binding for Gstreamer. Im using procedure from README from QtGStreamer package but I get some error while executing cmake command.
Basic info:
Mac OS X v. 10.6.8
GStreamer v. 0.10.36 + dependencies (installed through MacPorts)
Cmake v. 2.8.10 + dependencies (installed through MacPorts)
Boost v. 1.52.0 + dependencies (installed through MacPorts)
Qt v 4.8 (installed through SDK installer)
Sugested build procedure:
$ mkdir build && cd build
$ cmake .. -DCMAKE_INSTALL_PREFIX=/path/to/installation/prefix
$ make
$ make install
Result of cmake:
$ cmake .. -DCMAKE_INSTALL_PREFIX=/tmp1/install

I need this binding to develop an app for playing MJPEG/ASF streams from CCTV cameras. I have tried libvlc already but there is no easy way to capture streams while they are already displayed... GStreamer is the only alternative because it's gonna be cross platform application
I'm fairly new to C++/Qt programming and whole build/compile magic is still little bit confusing for me...
I know there is no simple answer how to build QtGstreamer binding but I'm gonna be very grateful for any help
