[Libav-user] Convert mkv to mp4 programmatically

[Gohar Hovhannisyan]

Hi Dear Team,

I've high definition mkv file and would like to convert it to smaller resolution mp4 file.
I know how to do it in command line (ffmpeg -i hd-movie.mkv -c:v libx264 -s:v 854x480 -c:a copy out.mp4)
  and would like to do it programmatically within iOS app.
Could you please assist me how I can do it (which headers I need, the functions, etc.)?

|Regards,
Gohar|
