Run FFMPEG command with commas and single quotes

Question

I am using FFMPEG-Kit for iOS BUT this issue applies to all releases of FFMPEG-Kit... within my command I run [1:v]format=argb,geq=r='r(X,Y)':a='0.5*alpha(X,Y)'[withOpacitySet] but it does not work, if I run the command without that it runs fine...

Is it the commas? The quotation marks?

Answer 1

with not much information, I am assuming you are missing double quotes in your filter try

[1:v]format=argb,"geq=r='r(X,Y)'":"a='0.75*alpha(X,Y)'[withOpacitySet];"

if that's not the case please share your input and/or other information.
