You might possibly also find the inter{audio,video}sink elements useful (in combination with an inter{audios,video}src in another pipeline. <div class="im"> > Also, out of interest, is there any reason why I can't link a pad > embedded in several layers of bins to another outside of these?

You can supply your own sink element, or a bin containing other elements and ending in a sink (then you need to create a ghost pad for the bin that points to the first element in the chain inside it). But just adding ghostpads won't achieve anything. No common ancestore usually either means you're trying to link an element that's not inside a pipeline/bin yet, or they're not at the same level inside the bin/pipeline hierarchy (the reasons ghostpads exist, so you can expose pads from inside a bin at the one-up bin level).
