<div dir="ltr">The GST_DEBUG shows me that the states are changing but I still do not see the messages. Also None of my queries seem to work. (Duration, Position) It seems like there is an issue with the gmainloop or something.

Does anyone know why this is? </div></div>You should probably provide a testcase (or at a minimum show the code you're talking about) if you want help with this sort of thing. Alternatively, run with GST_DEBUG and see what might be going wrong.
