The gstreamer blob has been split into four plugins: audiodecoder, camerabin, mediacapture, and mediaplayer. Note: camerabin is still disabled because it is untested camerabin2 implementation. A new qmake configuration use_gstreamer_camera has been introduced and is needed for the mediacapture plugin to expose the camera service. This configuration has been disabled by default. Shared functionality has been moved to the internal gsttools library. Change-Id: Ifb2604f440cfa97513d39f5d7978766c88eaec45 Reviewed-by: Michael Goddard <michael.goddard@nokia.com>
