The documented minimum GStreamer version for Qt Multimedia is 0.10.24, however, the camerabin plugin actually required 0.10.32 to compile successfully. The reason is mainly due to the GstEncodingProfiles API, which is used to implement the audio and video encoding settings controls. There's no hard requirement for that API anymore and the aforementioned controls simply don't do anything when the GStreamer version used to compile is older than 0.10.32. A few other GStreamer calls had to be ifdef'd or replaced in order to compile with 0.10.24. Note that this patch only makes sure it compiles with older versions, running the camerabin plugin with GStreamer < 0.10.32 is currently untested and it might not work as expected.
