Classes
struct	QoS
	This structure represents QoS for a given type. E.g. {"video_qos", <"video_framerate", 26>, <"video_depth", 9>}. More...
struct	SFPStatus
	This structure is defined for SFP1.0 Subsequent versions of the protocol may specify new structures. More...
struct	flowStatus
	Used to store the status of a flow. More...
exception	notSupported
exception	PropertyException
exception	FPError
exception	streamOpFailed
exception	streamOpDenied
exception	noSuchFlow
exception	QoSRequestFailed
interface	Basic_StreamCtrl
	Base class for StreamCtrl, implements basic stream start and stop functionality. More...
interface	Negotiator
	This interface is used to negotiate QoS between two stream endpoints. More...
interface	StreamCtrl
	Implementation the A/V StreamCtrl class. this class is used to control the stream. It should be subclassed by applications that want to provide more control features. More...
interface	MCastConfigIf
	Interface for multicasting operations. More...
interface	StreamEndPoint
interface	StreamEndPoint_A
	The "A" side of a streamendpoint. More...
interface	StreamEndPoint_B
	The "B" side of a streamendpoint. More...
interface	VDev
	Implements the VDev interface. One of these is created per connection, and represents device-specific parameters. More...
interface	MMDevice
	Implements a factory to create Endpoints and VDevs. More...
exception	protocolNotSupported
exception	formatNotSupported
exception	formatMismatch
exception	FEPMismatch
exception	alreadyConnected
exception	invalidSettings
exception	notConnected
exception	deviceQosMismatch
exception	failedToConnect
exception	failedToListen
interface	FlowConnection
interface	FlowEndPoint
interface	FlowProducer
interface	FlowConsumer
interface	FDev
struct	Position
exception	PostionKeyNotSupported
exception	InvalidPosition
interface	MediaControl
	MediaControl interface is similar to ControlledStream interface in MSS. It can be inherited by flow endpoints or FlowConnection interfaces. More...

Typedefs
typedef sequence< QoS >	streamQoS
	The QoS of a stream is a sequence of QoS structs (defined above) More...
typedef sequence< string >	flowSpec
typedef sequence< string >	protocolSpec
typedef sequence< octet >	key
	Used as a key for public-key encryption. More...
typedef CosPropertyService::Property	streamEvent
	Used to convey events, in Basic_StreamCtrl::push_event. More...
typedef sequence< FlowConnection >	FlowConnection_seq
typedef sequence < StreamEndPoint_A >	StreamEndPoint_A_seq
typedef sequence < StreamEndPoint_B >	StreamEndPoint_B_seq
typedef sequence< FlowEndPoint >	FlowEndPoint_seq
typedef sequence< Object >	Object_seq

Enumerations
enum	flowState { stopped, started, dead }
	Represents the state of a flow. More...
enum	dirType { dir_in, dir_out }
	The direction of a flow. More...
enum	PositionOrigin { AbsolutePosition, RelativePosition, ModuloPosition }
enum	PositionKey { ByteCount, SampleCount, MediaTime }
