I'm using system() to run ffmpeg, my problem is that I can't get to pass the arguments from outside this function. This is the code:

function videoFunction(videoFile)
vid = VideoReader(videoFile);
system('ffmpeg -i vid -vn audio.mp3');
disp('Audio extraído')
end

If I put the path to the video in -i video.avi instead of -i vid it would work but I need to pass it like I mentioned. Any ideas?

If your video file name is in variable videoFile, how about

strCommandLine = sprintf('ffmpeg -i %s -vn audio.mp3', videoFile);
system(strCommandLine);

Can you officially "Accept" it then? Thanks in advance.
