New Post: Play stream RTSP

Hello,

I have VLC 2.1.3 and use Logitech HD Pro Webcam C920.

I tried play stream with RTSP but cannot work. I get information about "failed to open/read to DVD". This code is right? What change in this code?
Vlc.DotNet.Core.Medias.MediaBase media = new Vlc.DotNet.Core.Medias.PathMedia(":dshow-vdev=USB2.0 Camera :dshow-adev=\"Logitech HD Pro Webcam C920\":live-caching=300");
            if (media != null)
            {
                media.AddOption("#transcode{vcodec=h264,vb=0,scale=0,acodec=mpga,ab=128,channels=2,samplerate=44100}:#rtp{dst=10.132.15.154,sdp=rtsp://10.132.15.154:8554/usb1}");
                VlcControl control = new VlcControl();
                control.Media = media;
                control.Play();
            }

Doing it in a loop just freezes it up.

I give it one of these:

vlcControl1.PositionChanged += vlcControl1_PositionChanged;

void vlcControl1_PositionChanged(VlcControl sender, Vlc.DotNet.Core.VlcEventArgs<float> e)
    {
        vlcControl1.AudioProperties.Volume = 0;
    }
Still there's a 1 seconds delay before it kicks in, less than ideal.

New Post: How is an error state cleared in the VLC control?

My project uses a VlcControl to display a play list of videos. If an error occurs in one of the videos (ex, file not found), the VlcControl enters an error state. The VlcControl no longer functions at this point.

Is there a way to get the error message? Can I clear the error state and continue?

I have tried calling GetErrorMessage and ClearError from the VlcContext but those don't seem to do anything.

Hi, guys.

I'm writing a app to play some videos (file and stream from IP cameras) and record too.
All of this must work simultaneously.
The problem is which, sometimes, I can't record videos when I'm playing videos. And, to record, I have to use 2 controls: 1 to record and 1 to view. I can't use the same control to record and see what I'm recording.
Sometimes I get the error:
"Could not load file or assembly 'Vlc.DotNet.Core.Interops, Version=1.2.0.0, Culture=neutral, PublicKeyToken=84529da31f4eb963' or one of its dependencies. The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020)"

program.cs
VlcContext.LibVlcDllsPath = CommonStrings.LIBVLC_DLLS_PATH_DEFAULT_VALUE_AMD64;
VlcContext.LibVlcPluginsPath = CommonStrings.PLUGINS_PATH_DEFAULT_VALUE_AMD64;

VlcContext.StartupOptions.IgnoreConfig = true;
VlcContext.StartupOptions.LogOptions.LogInFile = true;
VlcContext.StartupOptions.LogOptions.ShowLoggerConsole = false;
VlcContext.StartupOptions.LogOptions.Verbosity = debug ? VlcLogVerbosities.Debug : VlcLogVerbosities.None;

VlcContext.Initialize();

Application.Run(new Principal());

VlcContext.CloseAll();
my form
private void PlayVideo(string url)
{
    var media = new LocationMedia(url);
    vlcControl1.Media = media;
    vlcControl1.Play();
}

private void RecordVideo(string url)
{
    string path = Principal._Config.DiretórioRec;

    if (!Directory.Exists(path))
    {
    Directory.CreateDirectory(path);
    }

    if (Evento.cameraPreset.camera != null)
    {
    path = Principal._Config.DirectoryRec + @"\" + Evento.cameraPreset.camera.tower.name;

    if (!Directory.Exists(path))
    {
        Directory.CreateDirectory(path);
    }

    var arq = path + @"\" + Evento.arquivoVideo;

    var media = new LocationMedia(url);
    media.AddOption(":sout=#transcode{vcodec=theo,vb=800,scale=1,acodec=flac,ab=128,channels=2,samplerate=44100} :std{access=file,mux=ogg,dst=" + arq + "}");
    vlcControl2.Media = media;
    vlcControl2.Visible = false;
    vlcControl2.Playing += vlcControl2_Playing;
    vlcControl2.Play();
    }
}
vlcControl2_Playing just check if is time to stop recording.

How to work with multiple instances (read/write) of this library? Something with threads?

Also give it one of these to fix :)
        vlcControl1.Buffering += vlcControl1_Buffering;

    void vlcControl1_Buffering(VlcControl sender, Vlc.DotNet.Core.VlcEventArgs<float> e)
    {
        vlcControl1.AudioProperties.Volume = 0;
    }

Use timer to stop vlc recording and you can announce many instances as you want!

PathMedia only use for playing local video. when playing stream video you should use location like this:
media = new LocationMedia(url_source_protocol_stream_out) - that's enough to play a stream!
Your code:
media.AddOption("#transcode{vcodec=h264,vb=0,scale=0,acodec=mpga,ab=128,channels=2,samplerate=44100}:#rtp{dst=10.132.15.154,sdp=rtsp://10.132.15.154:8554/usb1}");
it is about streaming this video to new url with transcode

Yes, you can!
you can create how many instances as you want, and then just add urls by using locationMedia(url) to play the stream in this url.

Thank you leho for your reply.

I'm already using timers to stop recording.
The problem is which I can't start many instances without problems.
I think I have some problem with options of AddOption.

Commented Unassigned: Incompatibility? with release 2014.04.18 and previous [7810]

Need help resolving this issue? Maybe bug? Don't understand why a DVD reference in the log keeps popping up, not trying to record from dvd.

Ok, the latest greatest version was available so I update both VLC and VLC Dot.Net and have these issues;

Updated to the latest release: 2014.04.18
and get an error while trying to save stream to file. Previous version worked OK.
Trying to save from this stream:

//Timer used to control duration of recording

Hi theo2f!
Sometimes I faced this problem.
You only can view or record may be the reason is UDP stream, this only allow one job!
The solution is: You can add option to one instance to recording and view simultaneously.

What about this error: "the process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020)"

When you start new instance media (timer to stop and record again) you should stop current instance (.stop()) may be better after that dispose it and then add it again!
Hope these help you of the problems!

VlcContext.StartupOptions.LogOptions.Verbosity = VlcLogVerbosities.None;
VlcContext.StartupOptions.AddOption("--ffmpeg-hw");
VlcContext.StartupOptions.AddOption("--no-video-title-show");

VlcContext.Initialize();

VlcControl player = new VlcControl();

Binding bing = new Binding("VideoSource");
bing.Source = player;

Image img = new Image();
img.SetBinding(Image.SourceProperty, bing);
