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