i'm trying to use CodePlex with VLC version 2.2.x to be able to display audio bar graph.

can you please provide me some help for the below points?

the problems that i'm having are the following:
  • the audio bar graph is not displayed when i set in my PathMedia a physical file name.
    i passed in the startup options --config=C:\vlcrc,
    although if you call the vlc alone from GUI on version 2.2.x it displays the audio bar graph. this is the command that i run
    call "C:\vlc-2.2.0\vlc.exe" udp://@224.2.2.10:2010 --config=C:\vlcrc
  • when i set in my PathMedia a upd path "udp://@224.2.2.10:2010, it gives me this message in the log

Hello, I have a problem. It is impossible to control the sound through the library. Sets the value control.AudioProperties.Volume = 1; but the sound still continues to play as well as the value is always -1
VlcControl control = new VlcControl();
            Player pform = new Player();
            control.Dock = DockStyle.Fill;
            control.BackColor = Color.Green;
            pform.Controls.Add(control);
            MediaBase videomedia = new    Vlc.DotNet.Core.Medias.PathMedia(@"D:\user\video.mp4");
            control.AudioProperties.Volume = 1; // this always __-1__
            control.AudioProperties.IsMute = true; // this always __false__
            control.Play(videomedia);
what am I doing wrong?

New Post: 3 little problems

Please change in file Vlc.DotNet.Core.Interops\Signatures\LibVlcInterop.MediaPlayer.cs in line 671 "public delegate int GetStringMarquee(" to "public delegate string GetStringMarquee(".

The second problem is not so easy. I use 64-bit-Version for VLC. Then i must change the event-management: The "ObjectHandle" in the "struct LibVlcEventArgs" is a void-Pointer. That means for 32 bit a 4-byte-value, but for 64 bit is it a 8-byte-value! Therefor i must change the following Field-Offsets in the struct from 8 byte for the 32-bit-version to 12 byte for the 64-bit-version.
            [StructLayout(LayoutKind.Explicit)]
            public struct LibVlcEventArgs
            {
                [FieldOffset(0)]
                public EventTypes Type;

                [FieldOffset(4)]
                public IntPtr ObjectHandle;

                #region media descriptor

                __[FieldOffset(12)]__
                public MediaMetaChangedArgs MediaMetaChanged;
...
The 3. problem: The conversion for the timestamp is false. Perhaps VLC use another byte-order? I must use the highest 4 Byte as value:
private void OnVlcEvent(ref LibVlcEventArgs eventData, IntPtr userData) {
   switch (eventData.Type) {
...
      case EventTypes.MediaPlayerTimeChanged:
         long hw = eventData.MediaPlayerTimeChanged.NewTime >> 32;
         long lw = eventData.MediaPlayerTimeChanged.NewTime & 0xffffffff;
         EventsHelper.RaiseEvent(TimeChanged, this, new VlcEventArgs<TimeSpan>(TimeSpan.FromMilliseconds(lw != 0 ? lw : hw)));
         break;

hi,I use this dll in my application to display RTSP stream. It works fine at the first time,but not work when I want to display another RTSP stream address . I think the problem was mostly the lost of "=" in project Vlc.DotNet.Core VlcMediaList.cs function Clear():
public void Clear()
    {
        if (VlcContext.HandleManager.MediasListHandles.ContainsKey(this))
        {
            for (int index = Count - 1; index > 0; index--)
            {
                VlcContext.InteropManager.MediaListInterops.RemoveAt.Invoke(VlcContext.HandleManager.MediasListHandles[this], index);
            }
        }
    }
"index > 0" should be "index >= 0" , or MediaListInterops will allways reserves the first original object.
sorry for my poor english :(

Comments: Please read this thread - tell you all you need to know about using addoption against individual files. i had same issue when i wanted to set streaming options for each file: https://vlcdotnet.codeplex.com/discussions/544378

Comments: in summary - key issue is you have to add each option separately to the media (also replacing - with : )

Hello,

i have the same problem wich some other users. The CPU load is very high. I use Framework 4.5.1

My Code:
            VlcContext.StartupOptions.IgnoreConfig = true;
            VlcContext.StartupOptions.LogOptions.LogInFile = false;
            VlcContext.StartupOptions.LogOptions.ShowLoggerConsole = false;
            VlcContext.StartupOptions.LogOptions.Verbosity = VlcLogVerbosities.None;
            VlcContext.StartupOptions.AddOption("--ffmpeg-hw");
            VlcContext.StartupOptions.AddOption("--no-video-title-show");
Additional the VlcPlayer will stuttering slightly.
Can i optimize?

New Post: Playing a second youtube video

Hi,

I've a problem using MediaLocation object in WPF.
I can play a youtube video using this line of code:
Vlc.DotNet.Core.Medias.LocationMedia VlcMedia = New Vlc.DotNet.Core.Medias.LocationMedia(YoutubePath);
This works great with VlcMedia.StateChanged handler.

But, when my control is playing, if I want to start another youtube video, the Subitems property doesn't seem to be refreshed, and the first video replays.

I've tried to set VlcControl.Media == null; VlcControl.Media.Dispose... with no luck.

I supposed I miss something.

Have someone the same problem ? How to solve this ?
Thanks

Looks like VlcControl.Medias.Clear does'nt seem to clear the list... (?!)

I've found a workaround : call VlcControl.Medias.RemoveAt[0] just after setting the new one.
Strange behavior...!

I lack pretty much any and all programming knowledge but I have taken it onto myself to make a fairly complicated software for distribution as a freeware with separate payment options much alike donations.

Having VLC as part of my software is an almost vital part from lack of alternatives and I have failed to grasp how to include it as part of my resources and also how to include it into the final release. I tried looking around but lacking knowledge to understand the documentation here and also the names for what I am doing I cant seam to find help online either.

I am fairly confident that once I can get the functionality into my WPF project I can manage from there but I will also take my chance to ask for a few other key points at the end of this.

So how do I "Instal" the files I obtain from the zip file? Please be as specific as you can and also refrain from using any technical words and expect me to instantly understand what you are talking about.

Also how do I properly include it as a resource in my distribution so other people do not have to do anything other then instal my software?

After trying MediaElement and WMP, we're using this great library to build a video player in WPF.
How can I play DVD videos with interactive menus? (With the ability to navigate through it)
What I've tried so far:
mediaPlayer.Play(@"F:\");
mediaPlayer.Play(@"F:\VIDEO_TS");
mediaPlayer.Play("dvd:///F:\");
And if I directly play VTS_01_0.VOB the menu is not interactive

Thanks in advance for your help.
