Can't use Double quotes

[alsiPanda]

I am trying to run the following Ffmpeg command in ffmpy '-vf "curves=psfile=/filepath/file.acv" -c:a copy -f mp4'. I keep getting the error exited with status 1. I noticed the command being printed in the error message and that the double quotes were missing. I have tried the different variations shown in the docs under complex commands. But can't seem to get the double quotes where I want. It either surrounds the whole command or the last part. Here is the code I use:

    ff = ffmpy.FFmpeg(
        inputs={input_path: None},
        outputs={output_path: fc}
    )
    ff.run()

fc is fetched from a dictionary.

Try escaping the quotes: '-vf \"curves=psfile=/filepath/file.acv\" -c:a copy -f mp4'

Hi @Ch00k , Tried escaping. But getting the same error:

Please try to swap the quotes: double outside, single inside, like this: "-vf 'curves=psfile=/filepath/file.acv' -c:a copy -f mp4"

Is there another fix, this one doesn't work for me :(

        outputs={output_file: "-c:v copy -filter_complex '[1]adelay={}|{}[aud];[0][aud]amix'".format(delay,delay)}

yields

ffmpeg -i first.mp4 -ss 00:00:00 -i HdJaMadziCgQuWSIh3_0.mp3 -c:v copy -filter_complex [1]adelay=0|0[aud];[0][aud]amix first.mp4.tmp.mp4
