Constructor & Destructor Documentation

◆ TeletextPlugin()

ts::TeletextPlugin::TeletextPlugin ( TSP * tsp )

Constructor.

Parameters

[in] tsp Associated callback to tsp executable.

Member Function Documentation

◆ start()

virtual bool ts::TeletextPlugin::start ( )

overridevirtual

The main application invokes start() to start the plugin.

Optionally implemented by subclasses.

Returns: True on success, false on error (ie. not started).

Reimplemented from ts::Plugin.

◆ stop()

virtual bool ts::TeletextPlugin::stop ( )

overridevirtual

The main application invokes stop() to terminate the plugin.

Optionally implemented by subclasses.

Returns: True on success, false on error (ie. not started).

Reimplemented from ts::Plugin.

◆ processPacket()

virtual Status ts::TeletextPlugin::processPacket	(	TSPacket &	pkt,
		TSPacketMetadata &	pkt_data
	)

overridevirtual

Simple packet processing interface.

The main application invokes processPacket() to let the plugin process one TS packet.

Dropping or nullifying the packet is achieved by returning the appropriate status.

Dropping packets affects the output bitrate if the output device is a real-time one. With such devices, it is better to replace the undesired packet with a null packet.

Dropping a packet or changing its PID (including replacing a packet with a null one) affects the continuity counters of the other packets of the original PID.

Parameters

[in,out]	pkt	The TS packet to process.
[in,out]	pkt_data	TS packet metadata.

Returns: The processing status.

Reimplemented from ts::ProcessorPlugin.

◆ getPacketWindowSize()

virtual size_t ts::ProcessorPlugin::getPacketWindowSize ( )

virtualinherited

Get the preferred packet window size.

This method shall be overriden by plugins which prefer to use the "packet window" processing method.

Returns: The preferred number of TS packets to be processed at once in processPacketWindow(). If the returned value is zero, then TS packets are processed one by one using processPacket(). If this method is not overriden, the default implementation returns zero.

◆ processPacketWindow()

virtual size_t ts::ProcessorPlugin::processPacketWindow ( TSPacketWindow & win )

virtualinherited

Packet window processing interface.

The main application invokes processPacketWindow() to let the plugin process several TS packets at a time.

Parameters

[in,out] win The window of TS packets to process.

Returns: Number of processed packets inside win. When the returned value is less than win.size(), the packet processing is terminated after the specified number of packets. This is the equivalent of processPacket() returning TSP_END after the same number of packets. Dropping or nullifying individual packets is achieved by using the corresponding methods in the class TSPacketWindow.

◆ getOnlyExceptLabelOption()

void ts::ProcessorPlugin::getOnlyExceptLabelOption	(	TSPacketLabelSet &	only,
		TSPacketLabelSet &	except
	)		const

inherited

Get the content of the –only-label and –except-label options.

The values of these options are fetched each time this method is called.

Parameters

[out]	only	Set of labels from –only-label.
[out]	except	Set of labels from –except-label.

◆ type()

virtual PluginType ts::ProcessorPlugin::type ( ) const

overridevirtualinherited

Get the plugin type.

Returns: The plugin type.

Implements ts::Plugin.

◆ stackUsage()

virtual size_t ts::Plugin::stackUsage ( ) const

virtualinherited

Define the maximum stack usage for the thread executing the plugin.

If the method is not implemented by a subclass, the default value is DEFAULT_STACK_USAGE (128 kB).

Returns: The maximum stack usage in bytes for the thread executing the plugin.

Reimplemented in ts::DektecInputPlugin.

◆ getOptions()

virtual bool ts::Plugin::getOptions ( )

virtualinherited

The main application invokes getOptions() only once, at application startup.

Optionally implemented by subclasses to analyze the command line options. A plugin may ignore getOptions() and analyzes the command line options as part of the start() method. However, if a plugin is started later, command line errors may be reported too late.

Returns: True on success, false on error (ie. not started).

Reimplemented in ts::DektecInputPlugin, ts::AbstractDatagramInputPlugin, ts::AbstractDescrambler, ts::AbstractDuplicateRemapPlugin, ts::AbstractHTTPInputPlugin, ts::AbstractTablePlugin, ts::DebugPlugin, ts::FileInputPlugin, ts::FileOutputPlugin, ts::FilePacketPlugin, ts::ForkInputPlugin, ts::ForkOutputPlugin, ts::ForkPacketPlugin, ts::hls::InputPlugin, ts::hls::OutputPlugin, ts::HTTPInputPlugin, ts::HTTPOutputPlugin, ts::IPInputPlugin, ts::IPOutputPlugin, ts::IPPacketPlugin, ts::MemoryInputPlugin, ts::MemoryOutputPlugin, ts::NullInputPlugin, ts::PSIPlugin, ts::RISTInputPlugin, ts::RISTOutputPlugin, ts::SkipPlugin, ts::SRTInputPlugin, ts::SRTOutputPlugin, and ts::TablesPlugin.

◆ getBitrate()

virtual BitRate ts::Plugin::getBitrate ( )

virtualinherited

Get the plugin bitrate.

The main application may invoke getBitrate() at any time. The semantics depends on the capability.

Input plugin: Returns the current input bitrate of the device. Useful for real-time devices only.
Output plugin: Returns the current output bitrate which is used by the device.
Packet processing plugin: Return the current bitrate at the output of the packet processor. This can be used by packet processors which influence the bitrate by removing packets or introducing delays.

Optionally implemented by subclasses. By default, return that the plugin is not aware of the bitrate.

Returns: Plugin bitrate in bits/second. Shall return 0 on error or unknown bitrate.

Reimplemented in ts::DektecInputPlugin, ts::DektecOutputPlugin, ts::AbstractDatagramInputPlugin, and ts::VatekOutputPlugin.

◆ getBitrateConfidence()

virtual BitRateConfidence ts::Plugin::getBitrateConfidence ( )

virtualinherited

Get the plugin bitrate confidence.

When a subclass overrides getBitrate(), it should also override getBitrateConfidence().

Returns: The level of confidence of the bitrate value as returned by the previous call to getBitrate(). If the previous returned bitrate was zero, this confidence level shall be ignored.

Reimplemented in ts::DektecInputPlugin, ts::DektecOutputPlugin, ts::AbstractDatagramInputPlugin, and ts::VatekOutputPlugin.

◆ isRealTime()

virtual bool ts::Plugin::isRealTime ( )

virtualinherited

Tell if the plugin is a real time one.

Some plugin behave more accurately when the responsiveness of the environment is more accurate. Typically, input and output on tuners, modulators or ASI devices are real-time plugins. On the opposite, working on offline disk files is not.

This method shall be implemented by real-time plugins and shall return true. The default implementation returns false.

A plugin should be defined as real-time by design, not based on the interpretation of command-line parameters. Typically, the method isRealTime() is invoked before starting the plugin and consequently before the plugin has the opportunity to analyze its command-line parameters.

Returns: True if the plugin usually requires real-time responsiveness.

Reimplemented in ts::DektecInputPlugin, ts::DektecOutputPlugin, ts::AbstractDatagramInputPlugin, ts::hls::InputPlugin, ts::hls::OutputPlugin, ts::IPOutputPlugin, ts::IPPacketPlugin, ts::RISTInputPlugin, ts::RISTOutputPlugin, ts::SRTOutputPlugin, and ts::VatekOutputPlugin.

◆ handlePacketTimeout()

virtual bool ts::Plugin::handlePacketTimeout ( )

virtualinherited

Invoked when no packet could be retrieved within the specified timeout.

Get an OR'ed of all values of an integer option in the last analyzed command line.

This method is typically useful when the values of an option are taken from an Enumeration and each value is a bit mask. When specifying several values, the result of this method is a mask of all specified options.

Template Parameters

INT	An integer type for the result.

Parameters

[in]	name	The full name of the option. If the parameter is a null pointer or an empty string, this specifies a parameter, not an option. If the specified option was not declared in the syntax of the command or declared as a non-string type, a fatal error is reported.
[in]	def_value	The value to return in value if the option or parameter is not present in the command line.

Returns: The OR'ed values of the integer option.

Unlimited number of occurences.

To be used as value for parameter max_occur to indicate that there is no limit to the number of occurences of an option.

Warning: use only for max_occur (size_t ). Do not use for max_value (int64_t ) since size_t is uint64_t on 64-bit platforms.
