Anton Khirnov 6d592fbd0d avconv: split creating and (re-)configuring complex filtergraphs 
The current code is less than straightforward due to the fact that
output streams can be created based on filtergraph definitions. This
change should make the code simpler and more readable. It will also be
useful in the future commits.
