PidContextMap

typedef QMap<QtsPid,PidContext> QtsPesDemux::PidContextMap

private

Map of PID analysis contexts, indexed by PID value.

Constructor & Destructor Documentation

QtsPesDemux() [1/2]

QtsPesDemux::QtsPesDemux ( QtsPesHandlerInterface *  handler = 0, const QtsPidSet &  pidFilter = QtsAllPids  )

explicit

Constructor.

Parameters

[in]	pidFilter	Set of PID's to filter.

QtsPesDemux() [2/2]

QtsPesDemux::QtsPesDemux ( )

private

Member Function Documentation

setPesHandler()

void QtsPesDemux::setPesHandler ( QtsPesHandlerInterface *  handler )

inline

Set the PES packet handler.

Parameters

[in]

handler

The PES packet handler.

reset()

void QtsPesDemux::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 from QtsDemux.

Reimplemented in QtsTeletextDemux.

resetPid()

void QtsPesDemux::resetPid ( QtsPid  pid )

virtual

Reset the analysis context for one single PID.

Parameters

[in]

pid

PID to reset.

Reimplemented from QtsDemux.

Reimplemented in QtsTeletextDemux.

handlePesPacket()

void QtsPesDemux::handlePesPacket ( const QtsPesPacket &  packet )

protectedvirtual

This hook is invoked when a complete PES packet is available.

Can be overloaded by subclasses to add intermediate processing.

Parameters

[in]

packet

The PES packet.

Reimplemented in QtsTeletextDemux.

processTsPacket()

void QtsPesDemux::processTsPacket ( const QtsTsPacket &  packet )

privatevirtual

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

Parameters

[in]

packet

The TS packet to process.

Implements QtsDemux.

processPesPacket()

void QtsPesDemux::processPesPacket ( QtsPid  pid, PidContext &  pc  )

private

Process a complete PES packet.

Parameters

[in]	pid	The source PID.
[in,out]	pc	The PID analysis context.
