Comment (by robert_s):

 Is it possible that the H.265/HEVC decoder in ffmpeg cannot handle
 interlaced content yet? I do not see the progressive_source_flag,
 interlaced_source_flag or frame_only_constraint flag being evaluated
 anywhere in the source code...

 The "pic_height_in_luma_samples" being 544 seems to be right, as according
 to page 8 of ITU-T H.265/AVC:

 "NOTE – A picture may be either a frame or a field."

 So a 1080i stream, encoded in H.265/HEVC as 1088i, a field = picture would
 indeed have a height of 544 luma samples.
