Comment (by dhelsley):

 There are differences. In #4141, according to the comments the stream in
 question has field_seq_flag=1 but pic_struct=3, which is improper syntax,
 and the reference decoder does the same thing as FFMPEG (output half-
 height frames).

 With this particular elementary stream, field_seq_flag=1 and pic_struct=1
 or 2 depending on which field it is, which is valid interlaced syntax. The
 reference decoder produces proper the interlaced output frames with this
 test vector.
