can't change to mono-channel by command line

[jacky912]

Dear all,
I am using VB.net and having problem when I try to set the audio to left or right before play.

Here is the simple code that I was using.

Code: Select all

Dim lStrOption As String lStrOption = "--sout-mono-channel={0}" VLCPlayer.playlist.items.Clear VLCPlayer.playlist.Add lCurrentSongLocation, , lStrOption

I also try change the channel after the playlist.play. But it doesn't work as work (error occurred)

Code: Select all

VLCPlayer.playlist.Add lCurrentSongLocation VLCPlayer.playlist.Play VLCPlayer.audio.channel = 3

Is my question not clear enough?
Or it is hard to understand?

Please let me know. I can adjust.
Look forward to hearing from anyone who can help.

After few months, I still couldn't get it works.

Code: Select all

Dim lOption() As String = {":no-video-title-show", ":sout-mono-channel=0"} vlc.playlist.add("C:\abc.mpg", " ", lOption)

I just want to switch a Karaoke VCD file from both channel to left channel before the video started.
Please kindly teach me what is wrong.
Thanks

I am having the same problem here.
I searched the forum and found viewtopic.php?f=16&t=27710&start=0, but can't seem to work either.

I even want to have the ability to switch the channel during the video play.
Please advice. Thnx.

If the video file was played.
You can use the following code to switch through the left or right.

Code: Select all

If .audio.channel = 3 Then .audio.channel = 4 Else .audio.channel = 3 End If

I don't think it works that way.
I don't see .audio in the control object.

I'm using .NET

Ok, here is the step, hope it works for you:
1. Make sure the ActiveX control is existed on the Form (In my project, I named the VLC control to VLCPlayer)
2. the ".audio" is assumed, you have "With VLCPlayer" & "End With"

Exception occurs when executing vlc.audio.channel = 3

COMException was unhandled
Error HRESULT E_FAIL has been returned from a call to a COM component.

Hey.. it works..

Code: Select all

Dim lOption() As String = {":sout-mono-channel=0"} vlc.playlist.add(url,"A", lOption) vlc.playlist.play() vlc.audio.channel = 3

does prompt for exception when executing vlc.audio.channel = 3

but if i put the code:

Code: Select all

Private Sub ChangeToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ChangeToolStripMenuItem.Click If vlc.audio.channel = 3 Then vlc.audio.channel = 4 Else vlc.audio.channel = 3 End If End Sub

it works...
what if i want to set the channel default to 3 when the video starts?
