 Hi,

 Could you please implement a case when the filter (fieldhint) creates a
 frame using only one field.
 Example of a file containing hints (relative mode):
 {{{
 0,0 - # first frame
 1,0 - # second frame
 1,0 - # third frame
 1,0 -
 0,0 -
 0,0 -
 1,0 -
 ,0 -
 1,0 -
 0,0 -
 0,0 -
 1, -
 1,0 -
 1,0 -
 0,0 -
 }}}
 Some lines contain only one figure - that means 'use only one field to
 create this frame'.
 Sometimes interlaced videos contain errors like missing frame  between two
 adjacent frames. In this case, you can only use one field to create a
 frame.

 Thank you.
