FFMPEG script

I'd like to create a script that does the following:

FFMPEG script
I give the script path to a folder with videos
Script will scan all directories and subdirectories to find all video files

I give the script path where output videos will be copied
Script will mirror folder structure when copying files

Script will do
“ffmpeg -i input.mp4 -map 0 -c copy -movflags +faststart output.mp4”

Exemple :
I tell the script that output path is : D:\Output

video to be processed path:
C:\Part1\Breaking bad\VOSTFR\Episode1.mp4

Script will apply “ffmpeg -i input.mp4 -map 0 -c copy -movflags +faststart output.mp4” to “Episode1.mp4” and copy it to D:\Output\Part1\Breaking bad\VOSTFR\Episode1.mp4

PS : script is for WINDOWS
