Comment:

 ffmpeg will always demux/decode frames forward in time. `-sseof 0` would
 seek to EOF and, by definition, there are no frames at or beyond EOF. The
 last frames is one frame duration earlier than EOF.

 The typical way to export only this last frame to image is to make use of
 the update option of the image muxer.
