Constructor & Destructor Documentation

CMceVideoStream()

CMceVideoStream

(

)

[private]

C++ default constructor.

~CMceVideoStream()

IMPORT_C

~CMceVideoStream

(

)

Destructor.

Member Functions Documentation

AddCodecL(CMceVideoCodec *)

IMPORT_C void

AddCodecL

(

CMceVideoCodec *

aCodec

)

Adds codec to the stream. The codec contains preference value which will define its preference when added to the stream. Preference of codecs with the same preference value is determined by order they were added to the stream. In case of bound streams, codec is also automatically added to the opposite direction stream. After adding a codec an array of codecs received with a call to Codecs() is not valid.

Parameters

CMceVideoCodec * aCodec

codec added to the stream; ownership is transferred

BaseCodecs()

const RPointerArray < CMceCodec > &

BaseCodecs

(

)

[virtual]

Return codecs of stream.

Codecs()

IMPORT_C const RPointerArray < CMceVideoCodec > &

Codecs

(

)

Returns the codecs available to the session. For CMceOutSession , array contains all codecs supported by terminal in default. For CMceInSession , array contains codecs that were offered by remote terminal, and supported by local terminal. Codecs are in preference order in the array. Codec in the first element of the array has highest preference. Adding, removing or replacing a codec or changing the preference of a codec causes the returned array to be in invalid state.

ConstructL()

void

ConstructL

(

)

[private]

Second-phase constructor.

EventReceivedL(TMceEvent &)

TInt

EventReceivedL

(

TMceEvent &

aEvent

)

[virtual]

Traversal event handler.

Parameters

TMceEvent & aEvent

the event

ExternalizeL(MMceComSerializationContext &)

void

ExternalizeL

(

MMceComSerializationContext &

aSerCtx

)

[virtual]

Externalizes

Parameters

MMceComSerializationContext & aSerCtx

FindCodec(CMceCodec &)

CMceCodec *

FindCodec

(

CMceCodec &

aCodec

)

[virtual]

Searches for codec matching with input codec instance or sdp name

Parameters

CMceCodec & aCodec

the search term

InitializeL(CMceSession &, TBool)

void	InitializeL	(	CMceSession &	aParent,
			TBool	aDiscardUnusedCodecs
		)	[virtual]

Initializes the stream.

Parameters

CMceSession & aParent	the parent
TBool aDiscardUnusedCodecs

InitializeL(CMceManager *, CMceSession &)

void	InitializeL	(	CMceManager *	aManager,
			CMceSession &	aSession
		)	[virtual]

Initializes the stream.

Parameters

CMceManager * aManager	the manager; ownership is not transferred
CMceSession & aSession	the Session.

InternalizeL(MMceComSerializationContext &)

void

InternalizeL

(

MMceComSerializationContext &

aSerCtx

)

[virtual]

Internalizes

Parameters

MMceComSerializationContext & aSerCtx

IsAllowedCombination()

TBool

IsAllowedCombination

(

)

[protected, virtual]

Determine whether current combination of source and sinks is allowed for spesific stream type.

NewL()

IMPORT_C CMceVideoStream *

NewL

(

)

[static]

Two-phased constructor.

NewLC()

IMPORT_C CMceVideoStream *

NewLC

(

)

[static]

Two-phased constructor.

RemoveCodecL(CMceVideoCodec &)

IMPORT_C void

RemoveCodecL

(

CMceVideoCodec &

aCodec

)

Removes codec from the stream. In case of bound streams, codec is also automatically removed from the opposite direction stream. After removing a codec an array of codecs previously received with a call to Codecs() is not valid.

Parameters

CMceVideoCodec & aCodec

codec removed from stream

RemoveCodecL(CMceVideoCodec &, TBool)

void	RemoveCodecL	(	CMceVideoCodec &	aCodec,
			TBool	aBinderOriginated
		)

Removes codec

Parameters

CMceVideoCodec & aCodec
TBool aBinderOriginated

ReorderCodecsByPreferenceL(TBool)

void

ReorderCodecsByPreferenceL

(

TBool

aDiscardUnusedCodecs

)

[virtual]

Arrange video codecs according codec preferences.

Parameters

TBool aDiscardUnusedCodecs

ReplaceCodecsL(RPointerArray< CMceVideoCodec > *)

IMPORT_C void

ReplaceCodecsL

(

RPointerArray < CMceVideoCodec > *

aCodecs

)

Replaces codecs of the stream. Preference values of codecs will define the preference order. In case of bound streams, codecs are also automatically added to the opposite direction stream. After replacing codecs an array of codecs received with a call to Codecs() is not valid.

Parameters

RPointerArray < CMceVideoCodec > * aCodecs

array of codecs which will replace existing codecs; ownership is transferred

SupportedVideoCodecs()

IMPORT_C const RPointerArray < const CMceVideoCodec > &

SupportedVideoCodecs

(

)

const

Gets supported video codecs of the current stream configuration. Supported codecs for this video stream is affected by attached sinks and sources.

SynchronizeWithFileL(CMceFileSource &)

void

SynchronizeWithFileL

(

CMceFileSource &

aFile

)

[virtual]

Called file source wants to synchronized with stream

Parameters

CMceFileSource & aFile

the file source
