Hello. Sorry for bad english.

Im Using 0.3.1.0 and VB.NET

Question 1

Created a player. Thats all good going.
Im starting program and creating my player

Thats too much waiting for open video file on first run (thats checking plugins i think)
After first video loaded, no waiting again to open other videos.

"...Question 3

libvlc provides libvlc_video_take_snapshot() for that.

Maybe you should provide some details of your situation (OS, .NET version, libvlc wrapper, etc...). Someone familiar with what you're using
might be able to tell you if the libvlc function is exposed in your situation.

mangok thanks for relpy.

My OS : Windows Server 2003 (My application will run on different OSs)
.NET : 2008 (VB.NET im using)
VLC version 1.1.10

May i use that libvlc.dll

Code: Select all

Imports System
Imports System.Runtime.InteropServices

Public Class Form1
        Private declare Function  libvlc_video_take_snapshot lib "libvlc" ( How can i know which function needs which variables ) As Integer

      Private Sub form1_Load()

      End Sub
End Class

I don't khow how can i know functions needs which variables.

Code: Select all

libvlc_video_take_snapshot(Byval ???????????)

I checked that page for function variables

http://www.videolan.org/developers/vlc/ ... layer.html

but can't understand anything.

There are no sufficient help for VB.NET. Always C#, all samples for C#.

I need minimal VB.NET 2008 sample for (create new player, seek on video, get screenshot, pause, play and mute)
I will be grateful.
Inadvance Thanks for relations

the best way to know libvlc api is vlc source code itself : http://git.videolan.org/?p=vlc/vlc-1.1. ... nclude/vlc;

take a look at libvlc_media_player.h
