Combining (Sound File with a video file) and (reading certain interval of a sound file)

Hello, I have two questions:

1- How can I combine an existing sound and video files together in my matlab code eg: Video.avi + Sound.mp3 = video.avi but has the audio of 'Sound.mp3'

2-I want to read a specific time interval from a sound file eg: Sound.mp3 [10,40] --> This will read sound file from second 10 to second 40

Thanks in advance
