<DllImport("libvlc",CallingConvention:=CallinConvention.Cdecl)> _
Public Shared Function libvlc_audio_equalizer_set_amp_at_index( Byval equalizer as IntPtr, f_amp as Single, u_band as Integer) As Integer
Code: Select all
dim equal as Intptr = libvlc_audio_equalizer_new()
libvlc_audio_equalizer_set_amp_at_index(equal,10.2F,0)
libvlc_audio_equalizer_set_amp_at_index(equal,0F,1)
libvlc_audio_equalizer_set_amp_at_index(equal,-5.1F,2)
libvlc_audio_equalizer_set_amp_at_index(equal,10.0F,3)
libvlc_audio_equalizer_set_amp_at_index(equal,-10.2F,4)
libvlc_audio_equalizer_set_amp_at_index(equal,-20.0F,5)
libvlc_audio_equalizer_set_amp_at_index(equal,10.2F,6)
libvlc_audio_equalizer_set_amp_at_index(equal,10.2F,7)
libvlc_audio_equalizer_set_amp_at_index(equal,10.2F,8)
libvlc_audio_equalizer_set_amp_at_index(equal,10.2F,9)

note: i using 2.2.0 x64 and compiling my application as ANY CPU.
i'm tried to get amp after set amp
Code: Select all
libvlc_audio_equalizer_get_amp_at_index(equal,0)
this returns correct value which i applied before.
But why sound not affected by equalizer i have no idea.
Im working on hours for this problem.

I wrote some test code when the equalizer in LibVLC was first implemented, I've copied it here:
https://gist.github.com/caprica/1a6d0468675af33f7d36
The linked code contains test cases for setting equalizer before playback, during playback, having the equalizer settings persist when changing media and so on.
I just tested this against the latest vlc git and it works properly. I also test with Java bindings and it works fine there too.
I can only suggest that there must be something wrong with your language bindings, but I don't use whatever language it is you're using so I can't say any more.

"All my code below...."
Don't you need a call to libvlc_media_player_set_equalizer()? I thought THAT's when the change happened.

I FOUND PROBLEM
2.2.0 has problem. 3.0 nightly building working good without any code changes.
http://nightlies.videolan.org/build/win ... 2-win64.7z
So what can i do? I can't use nightly building. I must use stable version.

@sherington: is it working with 2.2.0 too?

I can no longer build vlc-2.2.0 git because of a fontconfig version conflict (0.19 vs 0.18) after I upgraded my OS, so I can't check the latest version.
The version of VLC installed by my OS is: 2.2.0-pre2 Weatherwax, changeset 2.2.0-pre1-15-g5178b24
I tested that just now and the equalizer seems to work just fine for me.

You can build VLC without fontconfig, you know?

Yep, my mistake, I got it working with fontconfig too but that's neither here nor there!
So I got a working vlc-2.2-git build at:
vlc: 2.2.0-rc2 Weatherwax, changeset 2.2.0-rc2-131-gf966a0f
I tested it just now and the equalizer works just fine.

Your problems with LibVLC will probably be over when 2.2.0 final is released, right now you're working with a pre-release version.
I can't provide you with any link, especially not for Windows, I build vlc from vlc-git and vlc-2.2-git on Linux regularly and I use that.
I do know that [KU]buntu 14.10 includes 2.2.0-rc2.

Sorry if I add to the thread only now. We moved from WMP to VLC in a production system last month, but we need the equalizer tool that is not available with the last official release (2.1.x). Can we use the 2.2.0 rc2 suggested ? We use VLC mainly to play OGG file.
Thanks in advance

Ok, thanks.
Right now, we are having another problem: since we have to play OGG file from a remote linux-based server, we need the plugin samba (plugin/access/libaccess_smb.dll) that is not linked on that "rc" version. How can we do ? Locally, at the windows client, the .ogg files play good and the equalizer is working (we use vlcj 3.1.0 to interface libvlc), but we cannot play the same files if they are on a remote linux server.

Windows has native Samba support.
