Member Functions Documentation

NewL(TUid, MMMFDevVideoPlayProxy &)

IMPORT_C CMMFVideoPostProcHwDevice *	NewL	(	TUid	aUid,
			MMMFDevVideoPlayProxy &	aProxy
		)	[static]

Creates a new video post-processor hardware device object, based on the implementation UID.

leave: "This method may leave with one of the system-wide error codes."

Parameters

TUid aUid	"Post-processor implementation UID."
MMMFDevVideoPlayProxy & aProxy	"The proxy implementation to use."

SetInputDevice(CMMFVideoDecodeHwDevice *)

void

SetInputDevice

(

CMMFVideoDecodeHwDevice *

aDevice

)

[pure virtual]

Sets the decoder device that will write data to this post-processor. Decoded pictures will be written with WritePictureL() or through a custom interface. After pictures have been processed, they must be returned to the decoder using ReturnPicture() .

Pre-condition: "This method can only be called before the hwdevice has been initialized with Initialize()."

Parameters

CMMFVideoDecodeHwDevice * aDevice

"The decoder source plug-in to use."

SetInputFormatL(const TUncompressedVideoFormat &)

void

SetInputFormatL

(

const TUncompressedVideoFormat &

aFormat

)

[pure virtual]

Sets the device input format to an uncompressed video format.

leave: "The method will leave if an error occurs. Typical error codes used: KErrNotSupported - The input format is not supported."

Pre-condition: "This method can only be called before the hwdevice has been initialized with Initialize()."

Parameters

const TUncompressedVideoFormat & aFormat

"The input format to use."

SetProxy(MMMFDevVideoPlayProxy &)

void

SetProxy

(

MMMFDevVideoPlayProxy &

aProxy

)

[protected, pure virtual]

Set the proxy implementation to be used. Called just after the object is constructed.

Parameters

MMMFDevVideoPlayProxy & aProxy

"The proxy to use."

WritePictureL(TVideoPicture *)

void

WritePictureL

(

TVideoPicture *

aPicture

)

[pure virtual]

Writes an uncompressed video picture to the post-processor. The picture must be returned to the client or source plug-in after it has been used.

leave: "This method may leave with one of the system-wide error codes."

Pre-condition: "This method can only be called after the hwdevice has been initialized with Initialize()."

Parameters

TVideoPicture * aPicture

"The picture to write."
