Before I start testing:
Could you confirm that the following shows a length 
of 2:17 ?
$ ffmpeg -i ./Red\ Balloon.mp3 -f null -

And is the problem reproducible with -vcodec mpeg4 ?

Why don't you specify an output frame rate if vpx 
does not support 1/ 5?
ffmpeg -f image2 ... -s 800x800 -r 15 out.webm
