+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)
