Well, Finally worked, :)
here is my recipe for others to try

var recipe = {
    transcriptionHooks: {
        "imBackHome": {
            pattern: "I am back home",
            command: "playVideo"
        }
    },

    commands: {
        "playVideo": {
            shellExec: {
            exec: "vlc --play-and-exit -f /path_to_file/modules/recipe/video1.mp4",
                // This command will play the video using VLC.
            }
        }
    }
};

exports.recipe = recipe;

If you want the vlc to just play the video without exiting, just remove " --play-and-exit".

Happy mirroring,
