In branch gstreamer/experimental

[sofian]

It seems to be linked to the gstreamer sdk. Before compiling I need to run /opt/gstreamer-sdk/bin/gst-sdk-shell. However once it's compiled, if I run while in the same shell, I have problems (only in multithreaded mode).

[sofian]

Actually those are two separate issues. There is a problem with the OpenGL video output in multithreading mode.
