This is true now, but it might not be true in the future.
In the output video device (that was sent by André but not yet upstream) for instance, only have a single
source pad (which I suppose the index will be 0), and this macro won't be true.
Maybe we could check pad flags in sd->entity->pads[index].flags ?
I think this change should be done in André's patch?
thanks,
