VB .Net 03 or 05 ActiveX example code.

[Mr Guest]

Just having a few issues.
Simply wanting to use the ActiveX with VB .Net.

Trawling through this forum I have found C# code that works nice but I would prefer VB. Someone did post a VB sample but it does not convert into .Net. Any example code where picking up a direct show from a web cam and recording to disk would be appreciated. Especially in the area of setting the Options array (:sout etc...)

Thanks in advance for any help.

I am also looking for some good and simple example using VLC activeX inside a VB .net 2005 program.

I am trying (in my program) to preview streming video coming from a video capture (connected to a cam) and transcode it to an mpeg4 file.

Have you found something useful?
Thanks anyway.

Using VB 2005 Express Edition, you can go to...
TOOLS > CHOOSE TOOLBOX ITEMS > COM COMPONENTS[tab] > Select the VIDEOLAN ActiveX component.

Now the component is in your toolbox. simply drag it to your form and you can edit its properties directly from the Properties window (including the mrl).

Works like a charm!

Thank you kaanuki!!!

I did as you suggested and now I have (in my form) a AxVLCPlugin1 control.

Now the problem is:
how can I play an .avi file?
how can I capture from my video capture device to an mpeg4 avi file?

Can you post or suggest some Visual Basic 2005 code to do such "simple" (not for me) things?

Many thanks in advance!!!

P.S: what is MRL?

I try to answer to my first question:

PLAYING AN AVI FILE

Private Sub btnPlay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPlay.Click
Dim MRLstring As String = Strings.Trim(txtDaRiprodurre.Text)
AxVLCPlugin1.addTarget(MRLstring, Nothing, AXVLC.VLCPlaylistMode.VLCPlayListAppendAndGo, -666)
AxVLCPlugin1.play()
End Sub

Private Sub btnStop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStop.Click
AxVLCPlugin1.stop()
End Sub

Private Sub btnPauseResume_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPauseResume.Click
If AxVLCPlugin1.Playing Then
AxVLCPlugin1.pause()
Else
AxVLCPlugin1.play()
End If
End Sub


txtDaRiprodurre is a textbox where user writes the complete path to the .avi file to play (blank spaces are deleted with Strings.Trim function).

To understand addTarget method take a look here:

Hope it helps.

Just a problem: when I stop playing and choose another file to play and press play again, the file that is played is always the first one that was played... WHY???

Thanks again to kaanuki and to Quovodis (in the other post I linked here above).

P.S: how can I capture from my video capture device to an mpeg4 avi file using an installed compressor-codec (such as DivX)?

Hi ,

I was trying to add this active X control in tool box as stated but i observed error that self registration of axvlc.dll is failed.
Even though i had latest version of VLC.

Where can i find the latest active x to use.

[myangga]

hi
did you select the activeX during the install ? 'cause it's not default.
bye

I have found that when I replace the line

Code: Select all

AxVLCPlugin1.addTarget(MRLstring, Nothing, AXVLC.VLCPlaylistMode.VLCPlayListAppendAndGo, -666)

with

Code: Select all

AxVLCPlugin1.addTarget(MRLstring, Nothing, AXVLC.VLCPlaylistMode.VLCPlayListAppendAndGo, 0)

You should be able to get it to play more than one file, I have found that this caused the stop button to have the same problem, but you can just disable the stop button if you find you have any problems with it. Hope this helps.

Thank you JamesMichael!

And what about capturing from a video capture device to an mpeg4 avi file using an installed compressor-codec (such as DivX)?

I need to control the VLC activeX component from inside Powerpoint.
Honestly... don't laugh.

I inserted the ActiveX component and created a button.
The hero() subroutine is a macro linked to the button.

The following code compiles and runs
Sub hero()
Dim strMRL As String
MsgBox ("hero")
strMRL = "C:\hero.mpg"
Original.MRL = strMRL
Original.Play
End Sub

Now I want to use the powerful yet troublesome addTarget method to be able to control the streaming of the file.
The following code compiles but does not run. I get a runtime error 5 Invalid procedure call or argument.

Sub hero()
Dim strMRL As String
MsgBox ("hero")
strMRL = "C:\hero.mpg"
Original.addTarget uri:=strMRL, Options:="", Mode:=VLCPlayListAppend, Position:=0
End Sub

For the option field I tried vbEmpty and Nothing...
NADA - the same run time error occurs

So I also kindly request a VB project that illustrates the various examples of playing and streaming.

Thanks

By this time you probably solved that issue.
So just to keep the thread consistent:
the file is (still) contained in the playlist.
obj.playlistClear () should help.
