Detailed Description

Abstract superclass for packetizer classes (sections or PES packets).

Constructor & Destructor Documentation

AbstractPacketizer()

ts::AbstractPacketizer::AbstractPacketizer ( const DuckContext &  duck, PID  pid = PID_NULL  )

protected

Constructor.

Parameters

[in]	duck	TSDuck execution context. The reference is kept inside the packetizer.
[in]	pid	PID for generated TS packets.

Member Function Documentation

setPID()

void ts::AbstractPacketizer::setPID ( PID  pid )

inline

Set the default PID for subsequent MPEG packets.

Parameters

[in]

pid

PID for generated TS packets.

getPID()

PID ts::AbstractPacketizer::getPID ( ) const

inline

Get the default PID for subsequent MPEG packets.

Returns

PID for generated TS packets.

setNextContinuityCounter()

void ts::AbstractPacketizer::setNextContinuityCounter ( uint8_t  cc )

inline

Set the continuity counter value for next MPEG packet.

This counter is automatically incremented at each packet. It is usually never a good idea to change this, except maybe before generating the first packet if the continuity must be preserved with the previous content of the PID.

Parameters

[in]

cc

Next continuity counter.

nextContinuityCounter()

uint8_t ts::AbstractPacketizer::nextContinuityCounter ( ) const

inline

Get the continuity counter value for next MPEG packet.

Returns

Next continuity counter.

getNextPacket()

virtual bool ts::AbstractPacketizer::getNextPacket ( TSPacket &  packet )

pure virtual

Build the next MPEG packet for the list of items (sections or PES) to pacjetize.

If there is nothing to packetize, generate a null packet on PID_NULL.

Parameters

[out]

packet

The next TS packet.

Returns

True if a real packet is returned, false if a null packet was returned.

Implemented in ts::Packetizer, and ts::PESPacketizer.

packetCount()

PacketCounter ts::AbstractPacketizer::packetCount ( ) const

inline

Get the number of generated TS packets so far.

Returns

The number of generated TS packets so far.

reset()

virtual void ts::AbstractPacketizer::reset ( )

virtual

Reset the packetizer.

All unfinished items (sections or PES packets) are dropped.

Reimplemented in ts::CyclingPacketizer, ts::Packetizer, ts::PESPacketizer, and ts::PESStreamPacketizer.

report()

Report & ts::AbstractPacketizer::report ( ) const

inline

Get a reference to the debugging report.

Returns

A reference to the debugging report.

duck()

const DuckContext & ts::AbstractPacketizer::duck ( ) const

inline

Get a reference to the TSDuck execution context.

Returns

A reference to the TSDuck execution context.

display()

virtual std::ostream & ts::AbstractPacketizer::display ( std::ostream &  strm ) const

virtual

Display the internal state of the packetizer, mainly for debug.

Parameters

[in,out]

strm

Output text stream.

Returns

A reference to strm.

Reimplemented in ts::CyclingPacketizer, ts::Packetizer, ts::PESPacketizer, and ts::PESStreamPacketizer.

configurePacket()

void ts::AbstractPacketizer::configurePacket ( TSPacket &  pkt, bool  nullify  )

protected

Configure a TS packet with continuity and PID.

Also increment the number of generated packet. So this method must be called exactly once per packet.

Parameters

[in,out]	pkt	TS packet to configure
[in]	nullify	Return a null packet instead (no data to return for now).
