为Xamarin Studio安装gstreamer-sharp(Gtk#)

Question

我需要为Xamarin Studio(Gtk #project)安装gstreamer-sharp.我安装了OSSBuild并添加到引用gstreamer-sharp.dll,调试后我得到了异常:

Gst.GLib.GException:Gst.Parse.Launch中没有元素"playbin"(String pipeline_description)

输出:

码:

    Gst.Application.Init ();
    GLib.MainLoop Loop;
    Gst.Element element;
    Loop = new GLib.MainLoop();
    element = Gst.Parse.Launch("playbin uri=http://ftp.nluug.nl/ftp/graphics/blender/apricot/trailer/Sintel_Trailer1.1080p.DivX_Plus_HD.mkv");
    element.Bus.AddSignalWatch();
    element.SetState( Gst.State.Playing);
    Loop.Run();

我明白,这只是我的错,所以我不需要解决这个问题,我需要重新安装gstreamer-sharp并在​​Xamarin中正确使用它.这是如何正确完成的？

PS我认为如果为.Net安装它的人也可以给我建议那就太好了.

我不得不使用不同的代码。这段代码工作正常：

        Gst.Application.Init ();
        var pipeDescription = "playbin uri=file:///a:/test.avi ";
        var pipeline = Gst.Parse.Launch(pipeDescription) as Gst.Bin; 
        var someElementInPipe = pipeline.GetChildByName("myBin") as Gst.Element;
        pipeline.SetState(Gst.State.Playing);
