ffmpeg audio encoding help

[marcorocchini]

Hi,

please do you have patience with a cat ?

I have this commandline

V:\automazioneclip\core\ffmpeg64bit332.exe -threads 12 -y -i "V:\autogen\AutogenSuRazor.avi" -i "V:\autogen\AutogenSuRazor.avi" -c:v libx264 -profile:v high422 -level:v 4.1 -g 33 -bf 2 -crf 20 -flags +ildct+ilme -top 1 -pix_fmt yuv422p -map 0:v:0 -filter_complex "[1:a:0]asplit=2[aout0][aout1];[aout0]pan=stereo|FL<0.5FL+0.5FR|FR<0.5FR+0.5FL[a20c];[aout1]pan=stereo|FL<FL+0.0FR|FR<FR+0.0FL[a21c]" -map [a20c]:a:0 -c:a:0 aac -b:a:0 768k -map [a21c]:a:1 -c:a:1 aac -b:a:1 768k -aspect 16:9 v:\out.mp4

I need to regulate the the audio output level volume in the the audio 1 and 2 of the output, with a sort of:

-af volume=1.5

I wonder: where I can collocate it or how I can do?
