Constructor & Destructor Documentation

NIPDemux()

ts::mcast::NIPDemux::NIPDemux ( DuckContext &  duck, NIPHandlerInterface *  handler = nullptr  )

explicit

Constructor.

Parameters

[in,out]	duck	TSDuck execution context. The reference is kept inside the demux.
[in]	handler	The object to invoke when information is found.

Member Function Documentation

setHandler()

void ts::mcast::NIPDemux::setHandler ( NIPHandlerInterface *  h )

inline

Replace the NIP handler.

Parameters

[in]

h

The new handler.

reset()

bool ts::mcast::NIPDemux::reset

(

const FluteDemuxArgs &

args

)

Reset the demux.

Parameters

[in]

args

Demux arguments.

Returns

True on success, false on error.

feedPacket() [1/2]

template<class Rep , class Period >

void ts::mcast::NIPDemux::feedPacket	(	const cn::duration< Rep, Period > &	timestamp,
		const IPPacket &	pkt
	)

The following method feeds the demux with an IP packet.

The packet is ignored if this is not a UDP packet.

Parameters

[in]	timestamp	Packet time stamp value. This value should be taken from a monotonic clock.
[in]	pkt	An IP packet.

feedPacket() [2/2]

template<class Rep , class Period >

void ts::mcast::NIPDemux::feedPacket	(	const cn::duration< Rep, Period > &	timestamp,
		const IPSocketAddress &	source,
		const IPSocketAddress &	destination,
		const uint8_t *	udp,
		size_t	udp_size
	)

The following method feeds the demux with a UDP packet.

Parameters

[in]	timestamp	Packet time stamp value. This value should be taken from a monotonic clock.
[in]	source	Source socket address.
[in]	destination	Destination socket address.
[in]	udp	Address of UDP payload.
[in]	udp_size	Size in bytes of UDP payload.

addSession()

void ts::mcast::NIPDemux::addSession

(

const FluteSessionId &

session

)

Add a FLUTE session in the DVB-NIP analyzer.

There is normally no reason to call this from the application. The analyzer always starts with the DVB-NIP Announcement Channel on reset(). Then, all declared sessions in the DVB-NIP tables are automatically added.

Parameters

[in]

session

The session id to add.

addProtocolSession()

void ts::mcast::NIPDemux::addProtocolSession	(	const TransportProtocol &	protocol,
		const FluteSessionId &	session
	)

Add a FLUTE or ROUTE session in the DVB-NIP analyzer.

There is normally no reason to call this from the application. The analyzer always starts with the DVB-NIP Announcement Channel on reset(). Then, all declared sessions in the DVB-NIP tables are automatically added.

Parameters

[in]	protocol	The file transport protocol.
[in]	session	The session id to add.

isFiltered() [1/2]

bool ts::mcast::NIPDemux::isFiltered	(	const IPAddress &	source,
		const IPSocketAddress &	destination
	)		const

Check if a UDP packet or FLUTE file is part of a filtered session.

Parameters

[in]	source	Source IP address.
[in]	destination	Destination IP address and UDP port.

Returns

True if the packet is part of a filtered session.

isFiltered() [2/2]

bool ts::mcast::NIPDemux::isFiltered

(

const FluteSessionId &

session

)

const

Check if a UDP packet or FLUTE file is part of a filtered session.

Parameters

[in]

session

FLUTE session id.

Returns

True if the packet is part of a filtered session.

getServiceLists()

template<class CONTAINER >
requires std::same_as<typename CONTAINER::value_type, ts::mcast::NIPDemux::ServiceListContext>

void ts::mcast::NIPDemux::getServiceLists

(

CONTAINER &

lists

)

const

Get a description of all service lists.

Parameters

[out]

lists

Returned container of service list descriptions. The list of sorted by file names of service lists.

getServices()

template<class CONTAINER >
requires std::same_as<typename CONTAINER::value_type, ts::mcast::NIPService>

void ts::mcast::NIPDemux::getServices

(

CONTAINER &

services

)

const

Get a description of all services.

Parameters

[out]

services

Returned container of service descriptions. The list of sorted by logical channel number (LCN).
