This command line works as expected:

c://ffmpeg/ffmpeg -i P1000479.mov -lavfi 
astats=metadata=1:reset=1,adrawgraph=m1=lavfi.astats.1.RMS_level:mode=line:slide=scroll:min=-90:max=0 
-pix_fmt yuv420p -t 5 -y test.mp4


However when I try to do exactly the same thing two times and combine 
the videos with vstack, then I get warnings "More than 1000 frames 
duplicated" "More than 10000 frames duplicated" and FFmpeg becomes 
extremely slow:

c://ffmpeg/ffmpeg -i P1000479.mov -lavfi 
[0]astats=metadata=1:reset=1,adrawgraph=m1=lavfi.astats.1.RMS_level:mode=line:slide=scroll:min=-90:max=0[1];[0]astats=metadata=1:reset=1,adrawgraph=m1=lavfi.astats.1.RMS_level:mode=line:slide=scroll:min=-90:max=0[2];[1][2]vstack 
-pix_fmt yuv420p -t 5 -y test.mp4

What's wrong with this command line?
Below is the console output.
