In the cases where it was useful to check this parameter, it was the plane 
height, yes. Dunno if the OMX spec says that it always is that, but if 
nSliceHeight > frame_height, I guess one should regard it as plane height.

And indeed it's odd to add the parameter without using it in the same 
patch. This was since the patch currently using it, #9, is a hack that 
isn't intended to be permanent.
