How to use pitch shifting module in Libvlc version 3.0.4 ?

Hi everybody.
I use the Libvlc3.0 library for my music player, I developed it on C # .net.
All the functions I expect have finished and run very well. But I need to add "pitch shift module" to use it. But I did not find any functionality in libvlc to do that.
Can someone guide me?
I think in libvlc3.0 did not update this function. But the Vlc Player application has been updated and used.
please help me, can the Development Team update this functionality in the next release?
Thanks everyone!

What wrapper are you using?
Have you tried passing the CLI arguments?
https://wiki.videolan.org/VLC_command-line_help/
Code: Select all
--pitch-shift=<float [-12.000000 .. 12.000000]>
Pitch Shift

Thanks you!
I'm using this Wrapp: "
https://github.com/higankanshi/Meta.Vlc"
I tried it and it does not work. I think the vlc command used for vlc.exe
But my player only wrap Libvlc.dll and libvlccore.dll
Is there any other way?

Don't know about Meta.Vlc much. This is what I'd do.
1. Figure out the command and arguments you need to achieve the result you want using the CLI and plain vlc.exe (no wrapper).
2. Then, use a maintained wrapper like Vlc.DotNet and pass the same arguments.
Good luck

Code: Select all
procedure TForm1.Button3Click(Sender: TObject);

VLCPlugin21.audio.channel := 4; //audio channel
end;
procedure TForm1.Button4Click(Sender: TObject);
begin
VLCPlugin21.input.rate := tmpo - 0.50; //for speed
end;

You cannot with the VLCPlugin21, no. You must use libVLC for this.

Hi,
I'm having the same problem, I tried with libvlc, but I still can't get it work , --pitch-shift.
Only with ffMpeg I can Adjust Pitch, Has anybody find a solution for libVLC, in Delphi or .Net ...?
I also try to figure it out in cmd line, but I can't find a solution.
Thanks,
Mihai
