Yeah, if anybody has a clue how to implement the work function for
an atsc_trellis_encoder.cc - I'm stuck. The code compiles but
segfaults, very likely due to using a simple:

  for (int i = 0; i < noutput_items; i++){
    d_trellis_encoder.encode(&out[i], &in[i]);

Mainly, I have no idea how output.size is created from
setOutputSize(atsci_trellis_encoder::NCODERS);

Would that be 12 * sizeof_atsc_data_segment ?
(NCODERS = 12)
