Comment (by jamal):

 The video decodes fine with ffvp9 is i use 2pass mode instead of 1pass to
 create it.

 {{{
 ./ffmpeg -t 5 -i test-720p.mpg -c:v libvpx-vp9 -cpu-used 1 -crf 10 -b:v 0
 -an -lag-in-frames 16 -frame-parallel 1 -pass 1 -f webm /dev/null && \
 ./ffmpeg -t 5 -i test-720p.mpg -c:v libvpx-vp9 -cpu-used 1 -crf 10 -b:v 0
 -an -lag-in-frames 16 -frame-parallel 1 -pass 2 test_vp9.webm
 }}}
