/* this benchmark recursively builds a pipeline and meassures the time to go
* from ready to paused.
* The graph size and type can be controlled with a few commandline args:
* -d depth: is the depth of the tree
* -c children: is the number of branches on each level
* -f <flavour>: can be a=udio/v=ideo and is conttrolling the kind of elements
* that are used.
