WPFMediaKit The D3DRenderer class provides basic functionality needed to render a D3D surface. This class is abstract. The D3DImage used to render video The Image control that has the source to the D3DImage We keep reference to the D3D surface so we can delay loading it to avoid a black flicker when loading new media Flag to tell us if we have a new D3D Surface available A weak reference of D3DRenderers that have been cloned Backing field for the RenderOnCompositionTargetRendering flag. Temporary storage for the RenderOnCompositionTargetRendering flag. This is used to remember the value for when the control is loaded and unloaded. TryLock timeout for the invalidate video image. Low values means higher UI responsivity, but more video dropped frames. Flag to reduce redundant calls to the AddDirtyRect when the rendering thread is busy. Int instead of bool for Interlocked support. Defines what rules are applied to the stretching of the video Gets or Sets the value that indicates how the video is scaled. This is a dependency property. Enables or disables rendering of the video Gets the natural pixel height of the current media. The value will be 0 if there is no video in the media. Internal method to set the read-only NaturalVideoHeight DP Gets the natural pixel width of the current media. The value will be 0 if there is no video in the media. Internal method to set the read-only NaturalVideoWidth DP Is true if the media contains renderable video Internal method for setting the read-only HasVideo DP Handler for when the D3DRenderer is unloaded Handler for when the D3DRenderer is loaded Initializes the D3DRenderer control Sets the backbuffer for any cloned D3DRenderers Configures D3DImage with a new surface. This happens immediately Invalidates any possible cloned renderer we may have Cleans up any dead references we may have to any cloned renderers Used as a clone for a D3DRenderer Renders the video with WPF's rendering using the CompositionTarget.Rendering event Configures D3DImage with a new surface. The back buffer is not set until we actually receive a frame, this way we can avoid a black flicker between media changes The unmanaged pointer to the Direct3D Surface Invalidates the entire Direct3D image, notifying WPF to redraw TryLock timeout for the invalidate video image. Low values means higher UI responsivity, but more video dropped frames. Creates a clone of the D3DRenderer. This is a work for the visual brush not working cross-threaded Creates a cloned D3DImage image of the current video frame. Return null in case of the frame is not valid. The image can be used thread-safe. Fires when a DVD specific error occurs Gets if the mouse is over a DVD button. This is a dependency property. Gets or sets if the DVD automatically plays when a DVD is inserted into the computer. This is a dependency property. This event is fired when a DVD is ejected from the computer. This is a bubbled, routed event. Fires when a DVD is inserted into the computer. This is a bubbled, routed event. Gets the current time the DVD playback is at. This is a read-only, dependency property. Gets or sets the directory the DVD is located at (ie D:\VIDEO_TS). If this is empty or null, then DirectShow will try to play the first DVD found in the computer. This is a dependency property. The SelectAngle method sets the new angle when the DVD Navigator is in an angle block Value of the new angle, which must be from 1 through 9 Returns the display from a submenu to its parent menu. Selects the specified relative button (upper, lower, right, left) Value indicating the button to select Leaves a menu and resumes playback. Plays the DVD forward at a specific speed The speed multiplier to play back. Plays the DVD backwards at a specific speed The speed multiplier to play back Play a title The index of the title to play back Plays the next chapter in the volume. Plays the previous chapter in the volume. Goes to the root menu of the DVD. Goes to the title menu of the DVD The Play method is overrided so we can set the source to the media The handler for when a new DVD is hit. The event is fired by the DVDPlayer class. The handler for when the mouse is over a DVD button. This event is fired by the DVD Player class. Fires when a new DVD is inserted into a DVD player on the computer. Fires when the DVD is ejected from the computer. This control is not finished. Do not use it ;) The MediaElementBase is the base WPF control for making custom media players. The MediaElement uses the D3DRenderer class for rendering video Fires when media has successfully been opened Fires when media has been closed Fires when media has completed playing Get the current state of the media player Defines the behavior of the control when it is unloaded Defines the behavior of the control when it is loaded Gets or sets the audio volume. Specifies the volume, as a number from 0 to 1. Full volume is 1, and 0 is silence. Gets or sets the balance on the audio. The value can range from -1 to 1. The value -1 means the right channel is attenuated by 100 dB and is effectively silent. The value 1 means the left channel is silent. The neutral value is 0, which means that both channels are at full volume. When one channel is attenuated, the other remains at full volume. Notifies when the media has failed and produced an exception Initializes the media player, hooking into events and other general setup.

Playback is stopped. Key exchange for DVD copy protection failed. Playback is stopped. DVD-Video disc is authored incorrectly for specification version 1. x. Playback is stopped. The disc cannot be played because it is not authored to play in the system region. You can try fixing the region mismatch by changing the system region with Dvdrgn.exe. Player parental level is lower than the lowest parental level available in the DVD content. Playback is stopped. Analog copy protection distribution failed. Playback stopped. No discs can be played because the system region does not match the decoder region. The disc cannot be played because the disc is not authored to be played in the decoder's region. Arguments for an event reporting a new DVD time. The current Dvd time reported. Plays a DVD disc or will play DVD video files from a path. Normally, when a DVD is played with a custom allocator, IVideoWindow will be queried from the graph. Since there will be no IVideoWindow in this graph the IDvdControl2 will crash when we try to use the SelectAtPosition and ActivateAtPosition. We get around this by sacrificing the Line21 pin and connecting it to another video renderer that does have an IVideoWindow, but we make sure to keep the actual hWnd hidden.

It's not needed that the filter is registered. The GetProcAddress function retrieves the address of an exported function or variable from the specified dynamic-link library (DLL). Handle to the DLL module that contains the function or variable. The LoadLibrary or GetModuleHandle function returns this handle. Pointer to a null-terminated string containing the function or variable name, or the function's ordinal value. If this parameter is an ordinal value, it must be in the low-order word; the high-order word must be zero. If the function succeeds, the return value is the address of the exported function or variable.


If the function fails, the return value is NULL. To get extended error information, call Marshal.GetLastWin32Error.
 Loads the specified module into the address space of the calling process. The specified module may cause other modules to be loaded. Pointer to a null-terminated string that names the executable module (either a .dll or .exe file). The name specified is the file name of the module and is not related to the name stored in the library module itself, as specified by the LIBRARY keyword in the module-definition (.def) file. This parameter is reserved for future use. It must be IntPtr.Zero. The action to be taken when loading the module. If no flags are specified, the behavior of this function is identical to that of the function. If the function succeeds, the return value is a handle to the module.
If the function fails, the return value is NULL. To get extended error information, call Marshal.GetLastWin32Error. The FreeLibrary function decrements the reference count of the loaded dynamic-link library (DLL). When the reference count reaches zero, the module is unmapped from the address space of the calling process and the handle is no longer valid. Handle to the loaded DLL module. The LoadLibrary or GetModuleHandle function returns this handle. If the function succeeds, the return value is nonzero.


If the function fails, the return value is zero. To get extended error information, call Marshal.GetLastWin32Error.

File name Combined path Provides collections of devices and compression codecs installed on the system. Devices and compression codecs are implemented in DirectShow as filters, see the class for more information. To list the available video devices:
Filters filters = new Filters(); foreach ( Filter f in filters.VideoInputDevices ) { Debug.WriteLine( f.Name ); }
Collection of available video capture devices. Collection of available audio capture devices. Collection of available video compressors. Collection of available audio compressors. A collection of Filter objects (DirectShow filters). This is used by the class to provide lists of capture devices and compression filters. This class cannot be created directly. Populate the collection with a list of filters from a particular category. Populate the collection with a list of filters from a particular category. Populate the InnerList with a list of filters from a particular category Get the filter at the specified index. Represents a DirectShow filter (e.g. video capture device, compression codec). To save a chosen filer for later recall save the MonikerString property on the filter:
string savedMonikerString = myFilter.MonikerString;
To recall the filter create a new Filter class and pass the string to the constructor:
Filter mySelectedFilter = new Filter( savedMonikerString );
Human-readable name of the filter Unique string referencing this filter. This string can be used to recreate this filter. getAnyMoniker take very long time, so use a cached value Create a new filter from its moniker string. Create a new filter from its moniker Retrieve the a moniker's display name (i.e. it's unique string) Retrieve the human-readable name of the filter Get a moniker's human-readable name based on a moniker string. This method gets a System.Runtime.InteropServices.ComTypes.IMoniker object. HACK: The only way to create a System.Runtime.InteropServices.ComTypes.IMoniker from a moniker string is to use System.Runtime.InteropServices.ComTypes.IMoniker.ParseDisplayName(). So I need ANY System.Runtime.InteropServices.ComTypes.IMoniker object so that I can call ParseDisplayName(). Does anyone have a better solution?
