All,is there any way to create regular C-Callbacks from within GST? I need some magic which provides a function pointer (to a block or method) which I can pass to a C func as callback.As far as I can see the underlying libffi supports this using ffi_prep_closure_loc(). Is this already available in GST?
No, but callbacks are available without using libffi. You use functions in the vm_proxy, see the GLUT bindings in the opengl branch of my repository for a simple example.
