No. By "ffmpeg" I meant libavcodec+libavformat which are compiled in to
MPlayer.

You can't use older version, since there is no way to tell it
what names the png files should get.
You could maybe use image2pipe, then you'd get a stream with
one png concatenated with the next, but I doubt avoiding to get
a newer mencoder is worth dealing with that.
