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

Hi Mohamed Maher,

This is a very simple task with ffmpeg api. I don't know how to do it in matlab. You can download ffmpeg api from the following location https://www.ffmpeg.org/download.html and search for the commands. you can get lot of help.

(1) ffmpeg -i video.avi -i sound.mp3 video.avi
