		What: dv1394 (a.k.a. "OHCI-DV I/O support" for FireWire)
		Contact: linux1394-devel@lists.sourceforge.net
		Description:
		New application development should use raw1394 + userspace libraries
		instead, notably libiec61883 which is functionally equivalent.

		Users:
		ffmpeg/libavformat (used by a variety of media players)
		dvgrab v1.x (replaced by dvgrab2 on top of raw1394 and resp. libraries)

		What: dv1394 (a.k.a. "OHCI-DV I/O support" for FireWire)
		Date: May 2010 (scheduled), finally removed in kernel v2.6.37
		Contact: linux1394-devel@lists.sourceforge.net
		Description:
		/dev/dv1394/* were character device files, one for each FireWire
		controller and for NTSC and PAL respectively, from which DV data
		could be received by read() or transmitted by write(). A few
		ioctl()s allowed limited control.
		This special-purpose interface has been superseded by libraw1394 +
		libiec61883 which are functionally equivalent, support HDV, and
		transparently work on top of the newer firewire kernel drivers.

		Users:
		ffmpeg/libavformat (if configured for DV1394)

		What: raw1394 (a.k.a. "Raw IEEE1394 I/O support" for FireWire)
		Date: May 2010 (scheduled), finally removed in kernel v2.6.37
		Contact: linux1394-devel@lists.sourceforge.net
		Description:
		/dev/raw1394 was a character device file that allowed low-level
		access to FireWire buses. Its major drawbacks were its inability
		to implement sensible device security policies, and its low level
		of abstraction that required userspace clients do duplicate much
		of the kernel's ieee1394 core functionality.
		Replaced by /dev/fw*, i.e. the <linux/firewire-cdev.h> ABI of
		firewire-core.

		Users:
		libraw1394 (works with firewire-cdev too, transparent to library ABI
		users)

		What: legacy isochronous ABI of raw1394 (1st generation iso ABI)
		Date: June 2007 (scheduled), removed in kernel v2.6.23
		Contact: linux1394-devel@lists.sourceforge.net
		Description:
		The two request types RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN have
		been deprecated for quite some time. They are very inefficient as they
		come with high interrupt load and several layers of callbacks for each
		packet. Because of these deficiencies, the video1394 and dv1394 drivers
		and the 3rd-generation isochronous ABI in raw1394 (rawiso) were created.

		Users:
		libraw1394 users via the long deprecated API raw1394_iso_write,
		raw1394_start_iso_write, raw1394_start_iso_rcv, raw1394_stop_iso_rcv

		libdc1394, which optionally uses these old libraw1394 calls
		alternatively to the more efficient video1394 ABI

		What: video1394 (a.k.a. "OHCI-1394 Video support" for FireWire)
		Date: May 2010 (scheduled), finally removed in kernel v2.6.37
		Contact: linux1394-devel@lists.sourceforge.net
		Description:
		/dev/video1394/* were character device files, one for each FireWire
		controller, which were used for isochronous I/O. It was added as an
		alternative to raw1394's isochronous I/O functionality which had
		performance issues in its first generation. Any video1394 user had
		to use raw1394 + libraw1394 too because video1394 did not provide
		asynchronous I/O for device discovery and configuration.
		Replaced by /dev/fw*, i.e. the <linux/firewire-cdev.h> ABI of
		firewire-core.

		Users:
		libdc1394 (works with firewire-cdev too, transparent to library ABI
		users)
