MMMFVideoPlayControllerCustomCommandImplementor Class Reference

class MMMFVideoPlayControllerCustomCommandImplementor

Client class to access functionality specific to a video playback controller.

The class uses the custom command function of the controller plugin, and removes the necessity for the client to formulate the custom commands.

MvpcDirectScreenAccessEventL(const TMMFDSAEvent)

void

MvpcDirectScreenAccessEventL

(

const TMMFDSAEvent

aDSAEvent

)

[pure virtual]

Pauses/Resumes video playback. This is to be used with direct screen access to indicate that the display has changed and should not be written to. This does not affect audio playback.

Since: 7.0s

Parameters

const TMMFDSAEvent aDSAEvent

Whether the video display should be active.

MvpcGetAudioEnabledL(TBool &)

void

MvpcGetAudioEnabledL

(

TBool &

aEnabled

)

[pure virtual]

Indicates whether audio is enabled.

Since: 7.0s

Parameters

TBool & aEnabled

On return, contains a boolean indicating whether audio is enabled.

MvpcGetCropRegionL(TRect &)

void

MvpcGetCropRegionL

(

TRect &

aCropRegion

)

[pure virtual]

Gets the crop region currently applied to the image

Since: 7.0s

Parameters

TRect & aCropRegion

The dimensions of the crop region, relative to the video image. If no crop region has been applied, the full dimensions of the video image will be returned.

MvpcGetFrameL(MMMFVideoFrameMessage &)

void

MvpcGetFrameL

(

MMMFVideoFrameMessage &

aVideoFrame

)

[pure virtual]

Gets a frame previously requested from the controller.

Since: 7.0s

Parameters

MMMFVideoFrameMessage & aVideoFrame

The handle of bitmap to retrieve frame to.

MvpcGetLoadingProgressL(TInt &)

void

MvpcGetLoadingProgressL

(

TInt &

aPercentageComplete

)

[pure virtual]

Gets the progress of loading a video clip.

Since: 7.0s

Parameters

TInt & aPercentageComplete

The progress loading the clip, as a percentage.

MvpcGetRotationL(TVideoRotation &)

void

MvpcGetRotationL

(

TVideoRotation &

aRotation

)

[pure virtual]

Queries the rotation that is currently applied to the video image.

Since: 7.0s

Parameters

TVideoRotation & aRotation

The applied rotation.

MvpcGetScaleFactorL(TReal32 &, TReal32 &, TBool &)

void	MvpcGetScaleFactorL	(	TReal32 &	aWidthPercentage,
			TReal32 &	aHeightPercentage,
			TBool &	aAntiAliasFiltering
		)	[pure virtual]

Gets the scale factor currently applied to the video image.

Since: 7.0s

Parameters

TReal32 & aWidthPercentage	The percentage (100 = original size) used to scale the width of the video image will be copied into here.
TReal32 & aHeightPercentage	The percentage (100 = original size) used to scale the height of the video image will be copied into here.
TBool & aAntiAliasFiltering	A boolean indicating if anti-aliasing filtering should be used. ETrue if anti-aliasing filtering is being used, EFalse if not.

MvpcPlayL(const TTimeIntervalMicroSeconds &, const TTimeIntervalMicroSeconds &)

void	MvpcPlayL	(	const TTimeIntervalMicroSeconds &	aStart,
			const TTimeIntervalMicroSeconds &	aEnd
		)	[pure virtual]

Sets a time window for video playback.

Since: 7.0s

Parameters

const TTimeIntervalMicroSeconds & aStart	Start time in milliseconds relative to the start of the video clip.
const TTimeIntervalMicroSeconds & aEnd	End time in milliseconds relative to the start of the video clip.

MvpcPrepare()

void

MvpcPrepare

(

)

[pure virtual]

Prepares the video clip to be accessed.

A call to this method tells the controller plugin to finalise its configuration and to prepare to start reading the video clip. It is not possible to play the video clip or query any of its properties (e.g. duration, meta data etc.) until the controller plugin has signified the completion of this method by generating a KMMFEventCategoryVideoPrepareComplete event.

Since: 7.0s

MvpcRefreshFrameL()

void

MvpcRefreshFrameL

(

)

[pure virtual]

Requests the controller to redraw the current frame.

Since: 7.0s

MvpcSetCropRegionL(const TRect &)

void

MvpcSetCropRegionL

(

const TRect &

aCropRegion

)

[pure virtual]

Selects a region of the video image to be displayed.

Since: 7.0s

Parameters

const TRect & aCropRegion

The dimensions of the crop region, relative to the video image.

MvpcSetDisplayWindowL(const TRect &, const TRect &)

void	MvpcSetDisplayWindowL	(	const TRect &	aWindowRect,
			const TRect &	aClipRect
		)	[pure virtual]

Sets the screen region to be used to display the video.

Since: 7.0s

Parameters

const TRect & aWindowRect
const TRect & aClipRect	The clip rect used to display the video.

MvpcSetRotationL(TVideoRotation)

void

MvpcSetRotationL

(

TVideoRotation

aRotation

)

[pure virtual]

Rotates the video image on the screen.

Since: 7.0s

Parameters

TVideoRotation aRotation

The desired rotation to apply.

MvpcSetScaleFactorL(TReal32, TReal32, TBool)

void	MvpcSetScaleFactorL	(	TReal32	aWidthPercentage,
			TReal32	aHeightPercentage,

		)	[pure virtual]

Scales the video image to a specified percentage of its original size.

Since: 7.0s

Parameters

TReal32 aWidthPercentage	The percentage (100 = original size) to be used to scale the width of the video image.
