Have a look at GstParamSpec in the api docs. There is
#define             GST_PARAM_MUTABLE_PAUSED
#define             GST_PARAM_MUTABLE_PLAYING
#define             GST_PARAM_MUTABLE_READY

be aware that its not widely used. So if you have a particular element where you
feel a parameter change is getting ignored under some condition, please file a
bug about it.
