Hello,
I'm using vlc dotnet in my application. But i don't want that users install vlc media player. Is there any way to use vlc dotnet with only dlls(libvlc.dll,libvlccore.dll)?
I set VlcContext.LibVlcDllsPath to DLL's path. But it gives an error that "accessviolationexception"
Thanks...
Does anyone know how to implement Media_Opened and Media_Ended event handlers for VlcControl media element?
If you know of any c# examples, in this project source, please reply.
Thanks,
RocketMan
Hi,
please help me too. I had the same problem, i used VLC 2.0.4 and the newst dll's from here but my appliction chrash with "Null exeptions..." (Win7, VB 2010 SP1)

eMail vulkan58@gmx.de
Please excuse me "mein grausames Englisch"
i use 2.0.4 same problem
when call
vlcControl1.Stop(); /freeze Program !
Source Code Problem line ;
internal void Stop()
{
VlcContext.InteropManager.MediaListPlayerInterops.Stop.Invoke(VlcContext.HandleManager.MediasListPlayerHandles[this]);
}
i hate this !
VlcContext.LibVlcPluginsPath = Application.StartupPath + "\\plugins";
copy vlc plugins folder your project !
thanks
I searched long Time for this problem
Is it possible to change the snapshot format to JPEG? I added the following line to the initialization but the TakeSnapshot method still produces PNG.
VlcContext.StartupOptions.AddOption("--snapshot-format=jpg");Need urgent help here, since many weeks as passed and still get no working video player.
I'm using VS2010 and vb is the code, so far i manage to import dll's place the vlcControl on a form (shows transparent but imagine that's ok) initialize context also runs ok.
When it gets to the part of attrib media the the vlc control just freezes, below de lines of code:
Dim NewMedia As MediaBase = New PathMedia(FVar.filme) 'movie path NewMedia.AddOption(":sub-file="+ FVar.legenda) 'sub path vlcOld.Media = NewMedia 'vlcControl named as vlcOld vlcOld.Play()
Try this:
context->CloseAll();
context->Initialize();
Is there any documentation or a sample project available somewhere? Posts on this forum mention a sample app within the download but that is not the case, there are just 5 dll files. The documentation tab looks like it's been empty for April 19th. I have nothing to go on here.
For sample, download source code. This contain also source sample for use in c#. If you need to use in vb.net I also I provide sample, but email me for this!
Thanks for that. I am trying to open the project in Microsoft Visual C# Express 2010 but am running into a problem with source control bindings and whether I choose to delete them or not I get a message about solution folders not being supported in this version of the application and cannot view the project properly.
Is there anything special I need to do to get it up and running?
YesFirst, it is
better to copythe filestovlc
in the project folder.Then, do notwant to use thecontrolinthe form.Especially withthe.Net
Framework 4in VS2010VB.NETthere are problemsinstantiatingthe control in form design.It 'better toputin placeapanelobjectand send thehandle to the object.
Vlcfilesto be copiedare:
vlc.dll
vlccore.dll
nlog.dll(ifI remember correctly)
theplugin folder.
Warning: These filesmust be located

My goal is to test h264 streaming. I wanted to start with the youtube example delivered as part of the WPF sample application but that did not work at all. I tried to create the callback function as a separate method to see if it was ever called, and it was not. Basically the callback below is never called:
var media = new LocationMedia(@"http://www.youtube.com/watch?v=WAjt5wPJVqM");
media.StateChanged +=
delegate(MediaBase s, VlcEventArgs<States> args)
{
if (args.Data == States.Ended)
{
var subItems = media.SubItems;
if (subItems.Count > 0)
{
myVlcControl.Play(subItems[0]);
}
}
};
Does anyone know how to debug this further?
Playback of video content (MOV files etc) works fine.
This implementation is the first I have found that integrates deep into WPF in the sense that you can place other WPF elements on top of the video. I need this feature so hence the motivation to get youtube and eventually streaming to work.
On another forum I found the answer. In the downloaded sample code, locate the lines listed above, then replace with this:
media.MediaSubItemAdded +=
delegate(MediaBase s, VlcEventArgs<MediaBase> args)
{
myVlcControl.Media = args.Data;
myVlcControl.Play();
};
myVlcControl.Media = media;
myVlcControl.Play();
When using the current VLC version I was able to stream h264 using this sample software.
Hi,
I am trying to stream IP TV but facing a strange problem. I am using the latest build and compiled it myself using VS2010.
My code successfully streams RTSP and HTTP, however as for UDP multicast streams the VLC control stops at the VLC debug message (Starting pre-buffering) and nothing happens.
Here is my code:
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using Vlc.DotNet.Forms; using Vlc.DotNet.Core.Medias; using Vlc.DotNet.Core; namespace WindowsFormsApplication1 { publicpartialclass Form1 : Form { public Form1() { InitializeComponent(); } privatevoid button1_Click(object sender, EventArgs e) { VlcContext.StartupOptions.IgnoreConfig = true; VlcContext.StartupOptions.LogOptions.LogInFile = true; // Shows the VLC log console (in addition to the applications window) VlcContext.StartupOptions.LogOptions.ShowLoggerConsole = true; VlcContext.StartupOptions.LogOptions.Verbosity = VlcLogVerbosities.Debug; ///1///var vlcControl = new Vlc.DotNet.Forms.VlcControl { Dock = DockStyle.Fill, BackColor = Color.Green }; this.panel1.Controls.Add(vlcControl); //vlcControl.Media = new LocationMedia(@"rtsp://apasfwl.apa.at:80/orf2_q4a/orf.sdp"); <===== WORKS//vlcControl.Media = new LocationMedia(@"http://listen.radionomy.com/smooth-riviera"); <===== WORKS vlcControl.Media = new LocationMedia(@"udp://239.255.4.2:2000"); // <===== Does NOT WORK vlcControl.Play(); } privatevoid Form1_Load(object sender, EventArgs e) { } } }
VLC Debug windows prints the following output:

Can you guys help me fix this?
I tested the the same UDP stream address using my VLC player from the same PC and I am able to stream just fine. I just noticed that VLC player only accepts the format: udp://@239.255.4.2:2000
Hi Josephnter85, did you find something to this problem?
I am trying to run two VLC players in the same application. That appear to create some conflicts as only one player seem to play at a time where the two players take turns in which one updates the frames.
I am suspecting that the static class VlcContext is designed for ONE player only. Have anyone looked into running multiple players inside the same .NET application and what changes that might require in the wrapper?
I have now tried to change the implementation of "VlcContext" from being a static class to an instantiated object. It required substantial changes in references all across the wrapper, to carry around a pointer to the "VlcContext" object. Unfortunately it did not improve the issue I was trying to solve - a significant stutter is still seen when running multiple instances of the VlcControl class within the same application.
This leaves me thinking if possibly the limitation is in VLC? Is it so that VLC only allow one instance running for each process ID?
