New Post: AddOption Rotate Video stream

May 24, 2013, 3:21 pm

Hi, it does not appear this control is developed any more.. I also encountered the problem with rotating the video, and the only way I was able to accomplish it with this library, is this approach:
  • save current video position
  • stop video, unload, destroy vlc control
  • recreate vlc control, with an additional "--video-filter=transform --transform-type=<angle>" startup parameter
  • reload video, scroll to saved position
  • resume playing
This works.. even though is hacky as can be, you can rotate the video and it only causes a short black flicker 0.5-1s because the video has to load again.

I've read and experienced that most advanced options of VLC player are not supported by the library at runtime at all. If someone knows a better way of doing it.. please let me know :)

New Post: Play video from memory stream or byte array

You should try named pipe for that.

pipe server side code handle the memory stream and write byte[] to pipe
vlcControl should be the client side.


----serverside-----
first a thread to create a 
        NamedPipeServerStream PipeServer =  new NamedPipeServerStream("nameofpipe", PipeDirection.Out);
        PipeServer.WaitForConnection();

        //when connected, there should be a loop to continous write byte[] to pipe server stream.
        PipeServer.Write(data1, 0, data1.Length);
----clientside-----
VlcVideoPlayer is an instance of VlcControl. Just notice the path:
        MediaBase media = new PathMedia(@"stream://\\\.\pipe\inesaVideo");
        VlcVideoPlayer.Media = media;
        VlcVideoPlayer.Play();
----other questions-----------
some time when I stop playing, VlcControl just halt....

This is working, but with some troubles. Video goes well a few seconds, and after that starts lagging. I think the problem is that the pipe transfer rate is too high, and VLC cannot play it. If I do Thread.Sleep(200) over the write cycle it helps, but this is not a solution. Any idea how to handle this?

New Post: Only Recording

I am trying to use this library to record an incoming stream over RTSP. I can make this work using a WPF application, this is no problem. However, I want to do this in a class library which will ultimately run in a service rather than an application.

Can this be done without a reference to the PresentationFramework, or the Winforms equivalent? Is this library only for the presentation layer?

Thanks

but this only play that specific track and no other.

Please, Pretty please with sugar on top, I need help...

I'm following the WPF example having copied the dlls and referenced in my project and have copied the code from; http://vlcdotnet.codeplex.com/wikipage?title=Wpf
 
However I get the following error;

I've noticed VlcLogOptions.Verbosities.Debug associated classes. Intellisense shows nothing.

Reopened Issue: Application not shuts down Correctly [6130]

Hello
 
I work with the Source Code 62051, on a Windows 7 64Bit.
 
If i start the Player play a movie and close the Windows Form application.
It not gets closesd fully. It hangs.
 
When i break the Debug i see it Hangs on the Line:

VlcContext.InteropManager.MediaPlayerInterops.Stop.Invoke(VlcContext.HandleManager.MediaPlayerHandles[this]);
in the File VlcControl.Common function public void Stop();
 
However if i stop the movie before i close the app it closes fully and goes back to Visual Studio.
 
I tried to fix the issue with a FormClose/Closing Event without any luck. If i try to stop the movie there the same Problem happens, i guess some Reference is not there anymore.
 
Second Thing:
 
Had to fix the Take_Snapshot function in Order to compile. Otherwise it is working fine.
 
public void TakeSnapshot(string filePath, uint width, uint height)
{
if (VlcContext.InteropManager != null &&
VlcContext.InteropManager.MediaPlayerInterops != null &&
VlcContext.InteropManager.MediaPlayerInterops.VideoInterops.TakeSnapshot.IsAvailable)
{
Dispatcher.BeginInvoke(DispatcherPriority.Background,
(Action)(() => VlcContext.InteropManager.MediaPlayerInterops.VideoInterops.TakeSnapshot.Invoke(VlcContext.HandleManager.MediaPlayerHandles[this], 0, StringToByteArray(filePath), width, height)));
}
}
private byte[] StringToByteArray(string str)
{
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
return enc.GetBytes(str);
}
 
Third:
 
When will the In Memory Snapshot function appear?
 
Forth:
 
vlcControl1.IsSeekable is missing.
vlcControl1.CanPause is missing.
 
Best Regrads and keep up that good Work
Really like the Api soon i use WPF as well to test that thing out :)

Hi everyone,

I am connecting with vlcPlayerControl to a network stream with below codes, but after connection to our IP camera my CPU usage increase to 70-80%.

Do you have any suggestion ?
try
                {
                    if ((this.vlcPlayerControl.IsDisposed) || (this.vlcPlayerControl == null))
                    {
                        this.vlcPlayerControl = new VlcPlayerControl();
                        this.vlcPlayerControl.Initialize();
                        this.vlcPlayerControl.Visible = true;
                    }
                    if (!this.vlcPlayerControl.IsInitialized)
                    {
                        this.vlcPlayerControl.Initialize();
                    }
                    
                    MediaInput input = new MediaInput(MediaInputType.NetworkStream, "rtsp://192.168.0.1/stream1");

                    this.vlcPlayerControl.Visible = true;
                    
                    if ((VlcPlayerControlState.Idle == this.vlcPlayerControl.State) || (VlcPlayerControlState.Paused == this.vlcPlayerControl.State))
                    {
                        this.vlcPlayerControl.Play(input);
                    }
                }

Correct XAML must have the VLC control as a child of the Grid element otherwise the VLC control dimensions will be wrong: {{ <Grid x:Name="parentGrid" Grid.Row="0"> <Wpf:VlcControl x:Name="myVlcControl" /> ... }} Having the VLC control in the XAML is good for a test prototype, for production code however, the VLC control should only be added as code-behind, to catch XAML run time exceptions (and recover) when the VLC control cannot be found: {{ VlcControl vlcPlayer = new VlcControl(); // Add the VLC control to the grid to give it dimensions. // However VLC does not paint on its control geometry // instead it paints on its "VideoSource" image parentGrid.Children.Add(vlcPlayer); // WPF dark magic ahead: run-time interpreted data binding // When the VLC video changes (is loaded for example), the grid displays the new video image Binding vlcBinding = new Binding("VideoSource"); vlcBinding.Source = vlcPlayer; // VLC paints into a WPF image Image vImage = new Image(); vImage.SetBinding(Image.SourceProperty, vlcBinding); // The WPF image is used by a WPF brush VisualBrush vBrush = new VisualBrush(); vBrush.TileMode = TileMode.None; vBrush.Stretch = Stretch.Uniform; vBrush.Visual = vImage; // The WPF brush is used by the grid element background parentGrid.Background = vBrush; }}
