Elements with multiple inputs should pull the same amount of data from
each pad. That's why buffer-frames is there, as a 'contract' that each
pull gives that many frames, and if there are less it means an event

There is the special case buffer-frames=0, which means the element
doesn't care. This is typically the case for single-in, single-out
elements like audioconvert. Ladspa in general does care, though, so it
has to have a nonzero buffer-frames.
