'How to use ffmpeg on iOS?

I have to use the following command for ffmpeg

ffmpeg -i "Video.mp4" -map 0:1 "AudioWithVocalfromStreamOne.mp3" -map 0:2 "AudioWithoutVocalfromStreamTwo.mp3"

I have successfully installed ffmpeg on my mac. I tried using FFMPEGWrapper, but it doesn't seem to take any such parameters for using "map".

I need to know how to extract the streams from a video. I already have access to the streams, as server side is providing it to me using ffprobe at their end.
