+Format negotiation
==================
The query_formats method should set, for each input and each output links,
channel layout, sample format and sample packing.
The lists are not just lists, they are references to shared objects. When
- the negociation mechanism computes the intersection of the formats
+ the negotiation mechanism computes the intersection of the formats

eventually chosen for a link amongst the remaining list, again, all
