[FFmpeg-user] c implementation of a basic ffmpeg command

[Patrick]

I have successfully created an xcode project with ffmpeg. I am just learning c and would like to carry out some basic ffmpeg command line equivalents , such as:

ffmpeg -y -ss 00:00:30.00 -t 59 -i songIn -ab 24k songOut

How would this line be implemented in objective c, and is there any tutorials out there that would explain it. I have searched and found that all examples and tutorials are directed to video only. Thanks for your help.
