[FFmpeg-user] Problem with astats and adrawgraph

Hello all,
I'd like to draw a curve of the RMS audio level with the following
command line. The problem is that the output is a black video and no
curve is visible.
c://ffmpeg/ffmpeg -i P1000479.mov -lavfi astats,adrawgraph=
m1="lavfi.astats.RMS level
dB":mode=line:slide=scroll:min=-100:max=100:size=1920
x270:fg1=0xffffffff:bg=0x000000ff -pix_fmt yuv420p -t 10 -y test.mp4
However when I replace
astats,adrawgraph=m1="lavfi.astats.RMS level dB"
for example by
signalstats,drawgraph=m1="lavfi.signalstats.YAVG"
then a curve is shown as expected.
What's wrong in this part?
astats,adrawgraph=m1="lavfi.astats.RMS level dB"
Below is the console output.
Thanks,
Michael
