 Summary of the bug:
 Value returned from dnxhd_decode_frame() is wrong. It only returns half of
 the buffer consumed.


 The problem is that buf_size is not decremented in 2nd field iteration.
 The solution would be to move line:
 {{{
   buf_size -= ctx->cid_table->coding_unit_size;
 }}}
 two lines up (before if() ).
