This interface is a primary control interface of the media renderer for rendering DVD video. It is implemented by the DVD renderer and defines MPEG and DVD specific synchronization and control primitives that will be used by the DVD navigator during playback.

A pointer to an IDVDRenderer interface can be obtained by calling the IUnknown::QueryInterface method of a DVD-Video object and specifying the IID_IDVDRenderer reference identifier.

The IDVDRenderer interface has the following methods.

Method Description

IDVDRenderer::RegisterSyncEvent

Binds an event handle to specific events in the DVD presentation.

IDVDRenderer::UnregisterSyncEvent

Stops the event notifications flow associated with a handle.

IDVDRenderer::Play

Starts typical decoding and rendering of a DVD stream.

IDVDRenderer::Abort

Aborts any decoding and rendering processes and flushes the internal data buffers.

IDVDRenderer::Pause

Pauses DVD rendering.

IDVDRenderer::Scan

Provides support for forward and reverse scan modes.

IDVDRenderer::Slow

Performs slow-motion forward and slow-motion reverse.

IDVDRenderer::Step

Causes the decoder to temporarily start playback to decode and display picture and then enter into paused state on return.

IDVDRenderer::SetAudioStreamType

Sets the audio decoder for a selected audio stream type.

IDVDRenderer::SetAudioStreamNumber

Sets the decoding stream number for audio.

IDVDRenderer::SetSubpictureStreamNumber

Sets the decoding stream number for a subpicture.

IDVDRenderer::SetPalette

Sets the subpicture palette.

IDVDRenderer::Highlight

Causes the decoder to display a highlight of the specified DVD button.

IDVDRenderer::GetHighlightedButton

Returns the currently highlighted button number.

IDVDRenderer::GetAudioCaps

Returns a bitmask identifying what audio capabilities are supported by the DVD-Video renderer.

IDVDRenderer::GetScanCaps

Returns a bitmask identifying which scan modes are supported by the DVD-Video renderer.

IDVDRenderer::SetAPS

Sets the Analog Protection Schema (APS).

IDVDRenderer::SetContentAspectRatio

Sets the content aspect ratio.

IDVDRenderer::SetDisplayAspectRatio

Sets the output display aspect ratio.

IDVDRenderer::SetAspectRatioMode

Sets the renderer choice of presentation.

The IDVDRenderer interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
