Hmmm. That message looks suspicious because it should not include the single
quotes. I wonder if the issue is shell quoting? Perhaps you should try
replacing single quotes (') with double (") or none at all. I am ignorant of

I try
ffmpeg -y -i "/storage/emulated/0/Download/(M4A_128K).m4a"
compand=0|0:1|1:-90/-900|-70/-70|-30/-9|0/-3:6:0:0:0
"/storage/emulated/0/Download/(M4A_128K)_1.m4a"
for dynamic range compression, but it call back: invalid argument

ffmpeg -y -i "/storage/emulated/0/Download/(M4A_128K).m4
I am using the following command to concatenate a PNG image to a MP4 video.
Both are of 920 × 256 resolution.
ffmpeg -loop 1 -vsync 2 -t '20ms' -i '/path/to/image' -t '20ms' -f lavfi -i

Thanks for your clear response, I see the problem.
I'm wondering if there is any way to somehow lower the threshold for dark
green areas in order to reduce/suppress shadows in the foreground stream?
For example to somehow preprocess the foreground to reduce the contrast of
the green content?
