Start playing audio from a buffer passed in.

The passed in audio /p audioBuf is converted (if necessary) to the flowgraph's sample rate, then played through the flowgraph as it is set up.

Parameters

[in]	bufSize	- the size of the audio buffer /p audioBuf
[in]	inRate	- the sample rate of audioBuf
[in]	type	- Currently unused! Please pass '0'.

		UtlBoolean	autoStopOnFinish = `TRUE`
	)

Start playing audio from a file.

Parameters

audioFileName	name of the audio file
repeat	TRUE/FALSE continue playing audio from the beginning after the end of file is reached.
toneOptions	TONE_TO_SPKR/TONE_TO_NET file audio played locally or both locally and remotely.

OsStatus pauseFile ( )

Tell fromFile resource to pause the currently playing file, if one is being played.

		int	numCodecs,
		OsSocket &	rRtpSocket,
		OsSocket &	rRtcpSocket,
		MpConnectionID	connID = `1`
	)

Starts receiving RTP and RTCP packets.

void stopReceiveRtp ( MpConnectionID connID = 1 )

Stops receiving RTP and RTCP packets.

OsStatus gainFocus ( void )

virtual

Informs the flow graph that it now has the MpMediaTask focus.

Only the flow graph that has the focus is permitted to access the audio hardware. This may only be called if this flow graph is managed and started!

Returns: OS_SUCCESS, always

Reimplemented from MpFlowGraphBase.

OsStatus loseFocus ( void )

virtual

Informs the flow graph that it has lost the MpMediaTask focus.

Only the flow graph that has the focus is permitted to access the audio hardware. This should only be called if this flow graph is managed and started!

Returns: OS_SUCCESS, always

Reimplemented from MpFlowGraphBase.

OsStatus postNotification ( const MpResNotificationMsg & msg )

virtual

posts a resource notification message to the Notification dispatcher.

If there is a notification dispatcher, this message is posted to it. Otherwise, the message is dropped.

The Notification Dispatcher is used to hold and notify users of notification messages. This is first being created to be used by resources, held here in the flowgraph, and used to pass notification up to the application level. In the future, this could be extended to allow filtering of notification messages - The one setting up the notification dispatcher could set properties on it to enable only certain types of messages to be sent up through it's framework.

Parameters

[in] msg - the notification message to post to the dispatcher.

Return values

OS_SUCCESS	if the message was successfully added to the dispatcher.
OS_LIMIT_REACHED	if the queue is full, and no more messages can be accepted.
OS_NOT_FOUND	if there's no dispatcher.

Reimplemented from MpFlowGraphBase.

MpConnectionID createConnection	(	int	maxRtpStreams = `1`,
