[Libav-user] image + song = video and still search

I managed to put together a png and an m4a into an
mp4, with

    ffmpeg -i IMG -i SONG OUT

but when I play it in mplayer it "works" only I can't
go back and forward (and the OSD is broke as well).

The files I use are, according to file(1):

    ISO Media, Apple iTunes AAC-LC (.M4A) Audio
    PNG image data, 1280 x 720, 8-bit/color RGB, non-interlaced

(Apple?! That was a surprise.)

What is the correct and optimal command for making an
mp4 out of that?
