Not only for legal reasons, it is because WebCore in WebKit needs to handle the
buffer ranges, etc. That's why the the pipeline is decoupled into two.

IMHO, the way to go is a message from the appsink because you can hook to it in
the mainloop or the element thread.

Anyway, for now we either go with this solution in WebKit or we just add a
probe in the sink pad of the appsink filtering those messages up to the bus.
