Member Function Documentation

void SH::RTPSourceSH::calcNptSeconds (  RPtr< MNRTPPacket > &  packet  )

int SH::RTPSourceSH::getNptSeconds (   )

returns the absolute position in the presentation

virtual SinkEndpoint** SH::RTPSourceSH::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::RTPSourceSH::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::RTPSourceSH::initSH (   )  [virtual]

See also: Base Reimplemented from SH::Base.

virtual bool SH::RTPSourceSH::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.

void SH::RTPSourceSH::notify (  Notification  attribute  )

virtual void SH::RTPSourceSH::pushReport (  ReportPtr  report, Direction  d )  [virtual]

pushReport(r) can be called on source and sink endpoints, which will in turn call their owning stream handler for forwarding the report into the same general direction. The specific stream handler must overload this call if it wants to evaluate the reports, or if it has downstream or well as upstream endpoints. If the SH does not care about reports and has endpoints on only one side, it needs not overload this function. The reports are ignored and deleted in that case. Reimplemented from SH::Base.

void SH::RTPSourceSH::setNptSeek (  int  npt  )

the position in presentation after a rtsp seek should be called for every rtsp play msg with a range parameter

void SH::RTPSourceSH::setRTPTimestamp (  int  idx, u_int32  rtptime )

set initial timestamp from RTP-Info field in RTSP PLAY response

void SH::RTPSourceSH::setSubsessionIndex (  int  idx  )

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

See also: Base Reimplemented from SH::Base.

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

See also: Base Reimplemented from SH::Base.

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