Constructor & Destructor Documentation

◆ QtsDvdProgramChainDemux() [1/2]

QtsDvdProgramChainDemux::QtsDvdProgramChainDemux	(	const QtsDvdTitleSet &	vts,
		int	pgcNumber,
		int	angleNumber,
		int	fallbackPgcNumber = `0`,
		int	transferSize = `QTS_DEFAULT_DVD_TRANSFER_SIZE`,
		int	minBufferSize = `DEFAULT_MIN_BUFFER_SIZE`,
		Qts::DvdDemuxPolicy	demuxPolicy = `Qts::NavPacksFixed`,
		QtlLogger *	log = `0`,
		QObject *	parent = `0`,
		bool	useMaxReadSpeed = `false`
	)

Constructor.

Progress reporting is automatically enabled.

Parameters

[in]	vts	Video title set to demux.
[in]	pgcNumber	Program chain number to demux. Starting at 1.
[in]	angleNumber	Angle number. Starting at 1.
[in]	fallbackPgcNumber	Program chain number if pgcNumber does not exist in the title set. If negative or zero, no fallback is used and an error is generated if pgcNumber does not exist.
[in]	transferSize	Data transfer size in bytes.
[in]	minBufferSize	The minimum buffer size is the lower limit of the buffered data. When the amount of data not yet written to the device is lower than this size, new data is pulled from the DVD.
[in]	demuxPolicy	Management policy for navigation packs.
[in]	log	Optional message logger.
[in]	parent	Optional parent object.
[in]	useMaxReadSpeed	If true, try to set the DVD reader to maximum speed.
