◆ QtsDvdDataPull() [1/3]

QtsDvdDataPull::QtsDvdDataPull	(	const QString &	deviceName,
		int	startSector,
		int	sectorCount,
		Qts::BadSectorPolicy	badSectorPolicy = `Qts::SkipBadSectors`,
		int	transferSize = `QTS_DEFAULT_DVD_TRANSFER_SIZE`,
		int	minBufferSize = `DEFAULT_MIN_BUFFER_SIZE`,
		QtlLogger *	log = `0`,

		bool	useMaxReadSpeed = `false`
	)

Constructor.

Progress reporting is automatically enabled.

Parameters

[in]	deviceName	DVD device name.
[in]	startSector	First sector to read.
[in]	sectorCount	Total number of sectors to read.
[in]	badSectorPolicy	How to handle bad sectors.
[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.
