I just found the solution to this problem myself:
astats=metadata=1:reset=1,adrawgraph=m1=lavfi.astats.1.RMS_level
The underline character is missing in the documentation, where the
option is called "RMS level dB". Same problem for most other options
too.
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?
Can not reproduce.
Please provide input files.
www.astro-electronic.de/P479_1s.mov
This is a one second segment of my video (and is produces the same
warnings as above), made with
ffmpeg -i P1000479.mov -c:v copy -c:a copy -t 1 -y P479_1s.mov
It's normal that the content is mostly black (with a few stars) and
audio is only background noise.
Still can not reproduce it. Make sure you use latest ffmpeg version.
I just downloaded it again, now it's a version from today. But the
problem is the same as before.
