http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html#Introduction
"Because ddrescue needs to read and write at random places, it only 
works on seekable (random access) input and output files."

http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html#Invoking-ddrescue
The format for running ddrescue is:
     ddrescue [options] infile outfile [logfile]

Dd and dd_rescue read the input file sequentially, and can therefore 
send the output to stdout. But ddrescue tries to rescue the good parts 
first and cannot produce a sequential output.


Best regards,
Antonio.
