Hey list,

‘extended\_encoder’ currently ignores whatever ‘get\_output\_conversion’  
returns. If you use FEC’s extended encoder and you reimplement  
‘get\_output\_conversion’, it gets ignored. A quick look at the  
available encoders in gr-fec shows, that none of them actually uses  
that method. Though the docs state that  
\* If ‘packed\_bits’, the block produces packed bits and the  
\* wrapper should unpack these (using, for instance,  
\* gr::block::unpack\_k\_bits\_bb(8)).

Thus I created a little patch which would fix that.  
Also I just sent a pull request for that.
