I'm not sure about the -filter_complex switch but I'm able to use 
complex filters with avconv just using the -vf switch and passing the 
appropriate filtergraph parameters. The filtergraph documentation here 
really helped me figure it out:

https://libav.org/libavfilter.html#Filtergraph-description

I'd try passing your filter with just "-vf".
