You can try with --postprocessor-args, but if you want to have full control, it's much easier and faster to callffmpeg as a separate process.
Hello,
I miss an option to specify that ffmpeg uses libfdk_aac to encode the aac audio output. When using ffprobe, it says, that audio files are encoded with Lavf58.29.100. I wish to use libfdk instead.
