ffmpeg -loglevel info -y \
      -re -i a.mp4 \
      -re -i b.mp4 \
      -filter_complex "[0:a][1:a] astreamselect=inputs=2:map=1 [out_a]"   \
      -map "[out_a]"  -vn   \
      -f framemd5 -

a.mp4 and b.mp4 are available on these direct links:
(they are 500k each)

with my patch it works good.
