virtual u_int32 SH::SendBlockSH::get_ssrc ( ) [virtual]

SH_RC SH::SendBlockSH::getPos ( long & pos )

virtual SinkEndpoint** SH::SendBlockSH::getSinkSpecs ( ) [virtual]

Provide a list of valid sink endpoint specifications to the graph manager.
getSinkPorts() is called by the graph manager and returns an array of pointers to EndpointSpec structures, or NULL if no endpoints in this direction are supported. It is typical that the length of such an array is 1, because several alternatives are specified by one EndpointSpec object, and the maximum number of identical Endpoints is a parameter of the EndpointSpec as well. The maximum number of endpoints may be dynamic, e.g. in an RTP source SH, new SSRCs or PTs will result in the provision of a new Endpoint. The array of endpoint specs is not NULL terminated, it is expected that the application knows the number of endpoints from numSinkSpecs().

Returns:
An array of endpoint specification.

Implements SH::Status.

virtual SourceEndpoint** SH::SendBlockSH::getSourceSpecs ( ) [virtual]

Provide a list of valid source endpoint specifications to the graph manager.
getSourceSpecs() works like getSinkSpecs() but on the source endpoint specifications.

Returns:
An array of endpoint specification.

Implements SH::Status.

virtual SH_RC SH::SendBlockSH::initSH ( ) [virtual]

initSH() initializes the stream handler, initializes the EndpointSpecs if necessary etc. Child classes should overload this function instead of using the constructor for initialization tasks, since virtual functions used in the process do not exist during the constructor call (unavailability of virtual functions is a restriction of the C++ standard). initSH() : Uninitialized -> Initialized * -> ( error, - )
Reimplemented from SH::Base.

virtual bool SH::SendBlockSH::isConnected ( ) const [virtual]

Indicate whether a sufficient number of endpoints are connected for the stream handler to be active.
True if a sufficient number of endpoints is connected for the stream handler to operate in a graph. This should always be true when the stream handler is part of an active graph. This can be called on all stream handlers of a graph to determine whether it will activate successfully.
Implements SH::Status.

virtual SH_RC SH::SendBlockSH::startStreaming ( ) [virtual]

Activate the stream handler. Threads may start at this time. The data starts to flow through this stream handler. Initialized -> Running Running -> - * -> ( error, - )
Reimplemented from SH::Base.

virtual SH_RC SH::SendBlockSH::stopStreaming ( ) [virtual]

Deactivate the stream handler. The data stops flowing through this stream handler. When this function returns, this stream handler's endpoints will not call pull() or push() on their peers any more. Running -> Initialized
Reimplemented from SH::Base.

virtual SH_RC SH::SendBlockSH::uninitSH ( ) [virtual]

For symmetry only. Could be performed by the destructor as well. uninitSH() : Initialized -> Uninitialized
Reimplemented from SH::Base.
