[gst-devel] spider not choses audioconvert

[in7y118 at public.uni-hamburg.de]

That is indeed correct behaviour from spider.
It takes the highest ranked element that can connect both elements (sink and 
source padtemplate caps match those of the connected element). This element 
happens to be volume.

Now whoever decided that volume is a good element for autoplugging and then 
gave it a rank, I don't know though.

Someone should reduces volumes rank to below audioconvert's to fix this. If 
you want to be sure this happens, file a bug. Or bug people in #gstreamer 
yourself.
