This relies on specific structure of interface{} being composed of two
gpointer's. The code expects something along the lines of:
```
/*
void cb_proxy(void* v, void* v2);
*/
import "C"
//export cb_proxy
func cb_proxy(v unsafe.Pointer, v2 unsafe.Pointer) {
println("in cb_proxy")
el := (*C.GstElement)(v)
cb := (*gst.Element)(v2)
mycall(el, cb)
}
func mycall(webrtc *C.GstElement, user_data *gst.Element) {
}
...
func main{
...
source.SetCallback("on-negotiation-needed", C.cb_proxy)
...
}
```

Not sure about this API. It may require some additional changes to make it easier to use, but it seems to work and does simplify some things. I updated the dynamicpipeline demo here: https://github.com/tomberek/gst-go-demo
Fixes #5
