Member Function Documentation

setUnicast()

void ts::UDPReceiverArgs::setUnicast	(	const IPv4SocketAddress &	local_address,
		bool	reuse_port = true,
		size_t	buffer_size = 0
	)

Set application-specified parameters to receive unicast traffic.

This method is used when command line parameters are not used.

Parameters

[in]	local_address	Optional local address and required UDP port.
[in]	reuse_port	Optional reuse-port option.
[in]	buffer_size	Optional socket receive buffer size.

defineArgs()

void ts::UDPReceiverArgs::defineArgs ( Args &  args, bool  with_short_options, bool  destination_is_parameter  )

inline

Add command line option definitions in an Args.

Parameters

[in,out]	args	Command line arguments to update.
[in]	with_short_options	When true, define one-letter short options.
[in]	destination_is_parameter	When true, the destination [address:]port is defined as a mandatory parameter. When false, it is defined as option –ip–udp (optional, can be omitted)

loadArgs()

bool ts::UDPReceiverArgs::loadArgs ( DuckContext &  duck, Args &  args, cn::milliseconds  default_receive_timeout = cn::milliseconds(-1)  )

inline

Load arguments from command line.

Args error indicator is set in case of incorrect arguments.

Parameters

[in,out]	duck	TSDuck execution context.
[in,out]	args	Command line arguments from which to load the parameters.
[in]	default_receive_timeout	Default receive timeout in milliseconds. No timeout if zero or negative.

Returns

True on success, false on error in argument line.

Member Data Documentation

destination

IPv4SocketAddress ts::UDPReceiverArgs::destination {}

Destination of packets to read ([address:]port).

The UDP port is mandatory. The IP address is optional. When present, it must be a multicast address. When the IP address is not present, receive unicast packets on the specified UDP port.

source

IPv4SocketAddress ts::UDPReceiverArgs::source {}

Optional source (--source address[:port]).

The packets are accepted only is they come from the corresponding source. If the source IP address or source UDP port is unspecified, any address or port is accepted. If use_ssm is true, the source is used in source-specific multicast.
