Detailed Description

Abstract base class for transport stream demultiplexers.

Constructor & Destructor Documentation

QtsDemux() [1/2]

QtsDemux::QtsDemux ( const QtsPidSet &  pidFilter = QtsAllPids )

explicit

Constructor.

Parameters

[in]

pidFilter

Set of PID's to filter.

~QtsDemux()

QtsDemux::~QtsDemux ( )

virtual

Virtual destructor.

QtsDemux() [2/2]

QtsDemux::QtsDemux ( )

private

Member Function Documentation

feedPacket()

void QtsDemux::feedPacket

(

const QtsTsPacket &

packet

)

Feed the demux with a TS packet.

Parameters

[in]

packet

TS packet from the stream to demultiplex. If the PID of the packet is not in the PID filter, it is ignored.

setPidFilter()

void QtsDemux::setPidFilter ( const QtsPidSet &  pidFilter )

virtual

Set the list of PID's to filter.

Parameters

[in]

pidFilter

Set of PID's to filter.

addPid()

void QtsDemux::addPid ( QtsPid  pid )

virtual

Add a PID to filter.

Parameters

[in]

pid

PID to filter.

removePid()

void QtsDemux::removePid ( QtsPid  pid )

virtual

Remove a PID to filter.

Parameters

[in]

pid

PID to no longer filter.

filteredPidCount()

int QtsDemux::filteredPidCount ( ) const

inline

Get the number of PID's which are filtered by the demux.

Returns

The number of PID's which are filtered by the demux.

reset()

void QtsDemux::reset ( )

virtual

Reset the analysis context (partially built PES packets).

Useful when the transport stream changes. The PID filter and the handlers are not modified.

Reimplemented in QtsTeletextDemux, QtsSectionDemux, QtsStandaloneTableDemux, and QtsPesDemux.

resetPid()

void QtsDemux::resetPid ( QtsPid  pid )

virtual

Reset the analysis context for one single PID.

Parameters

[in]

pid

PID to reset.

Reimplemented in QtsTeletextDemux, QtsSectionDemux, QtsStandaloneTableDemux, and QtsPesDemux.

lastPcr()

qint64 QtsDemux::lastPcr ( ) const

inline

Get the last PCR found in the stream.

Returns

Last PCR value or negative if none was found.

packetCount()

QtsPacketCounter QtsDemux::packetCount ( ) const

inline

Get the number of process TS packets.

Returns

The number of process TS packets.

resetPacketCount()

void QtsDemux::resetPacketCount ( )

inline

Reset the number of process TS packets.

processTsPacket()

virtual void QtsDemux::processTsPacket ( const QtsTsPacket &  packet )

privatepure virtual

Feed the demux with a TS packet (PID already filtered).

Must be implemented by subclasses.

Parameters

[in]

packet

The TS packet to process.

Implemented in QtsSectionDemux, and QtsPesDemux.
