Strange the example
avconv -i in.mp4 -i in.png -filter_complex
'overlay=x=10:y=main_h-overlay_h-10' /tmp/out.mkv
Works exactly as supposed to and chaining two overlays
avconv -i in.mp4 -i in1.png -i in2.png -filter_complex
overlay=x=10:y=H-h-10,overlay=x=W-w-10:y=H-h-10' /tmp/out.mp4
Work just fine as well.

I'm doing that with the current version of libav (11), and the online
documentation refers to master, maybe you are using the new syntax on
the old version.
