Powershell: MP4 to MP3, using FFMPEG

Using your favorite website, to download a YouTube vid, as an MP4 video…
Such as:

https://www.youtube.com/watch?v=NTvcNm1ksRg

https://y2mate.com/youtube/NTvcNm1ksRg

Then using ‘FFMPEG’, to grab the audio, from that MP4… As an MP3 audio file.

This script opens a file select dialog, where you can select the MP4 file…
And then proceeds make the MP3, as a new file – In the source folder.
Then opens up the location of the MP3, wit that file selected.

Notice that there is a flag that will allow the selection of multiple files – It is intentionally called, and set to ‘Multiselect = $false’, because otherwise, every MP3 file, is gonna have the same name, with subsequent files showing numeric iterations parenthetically.

Change the ‘$fileName’ – That MP4 you downloaded has a crappy file name…
Change the path of the ‘ffmpeg.exe’.

# Could also do this... The file name, via a $fileName = Read-Host $fileName = "Billy Squier - Everybody Wants You" #just the name - MP3 is added in below $fileName = $fileName+".mp3" Add-Type -AssemblyName System.Windows.Forms $FileBrowser = New-Object System.Windows.Forms.OpenFileDialog -Property @{     InitialDirectory = "C:\Users\Rich\Downloads"     Multiselect = $false # Multiple files can be chosen     Filter = 'Video (*.MP4)|*.mp4' # Specified file types     Title = "Select file..."     } [void]$FileBrowser.ShowDialog() $file = $FileBrowser.FileName If($FileBrowser.FileNames -like "*\*") { $Path_to_File = $FileBrowser.FileName $Path_to_File } else {     Write-Host "Cancelled by user"     break } $OutputFolder = "C:\Users\Rich\Music\" $Output = $OutputFolder+$fileName & "C:\Users\Rich\Extracted Applications\ffmpeg\ffmpegWin64\bin\ffmpeg.exe" -i $Path_to_File $Output # Open the folder the MP3 was saved to,,, explorer.exe /select,$Output
