Announcing libavc1394 and librom1394 for GNU/Linux IEEE 1394

[Dan D. <dde...@co...>]

Based upon code from gscanbus, Kino, and dvcont, I have created libraries
libavc1394 and librom1394. They are hosted at
http://sourceforge.net/projects/libavc1394/.

libavc1394 is a very limited implementation of the AV/C protocol
specification. It includes functionality currently required by gscanbus,
Kino, and dvcont. The new Kino v0.42 has been ported to use it as well as
dvcont. dvcont is now a part of libavc1394 (in the test directory) thanks
to Jason Howard.

librom1394 provides a simple API to the IEEE 1394 CSR Configuration ROM in
all 1394 devices. It reads the directory in each device to get a textual
description of a device and to identify the type of device (AV/C, Digital
Camera, SBP-2, etc.) In order to properly read the description of the
GNU/Linux IEEE 1394 OHCI driver, you need the latest ohci1394.c from CVS,
which repairs the directory structure of its rom. If you do not have it,
you can expect to receive warnings on stderr "invalid number of textual
leaves." Included is a test program called testrom that provides a full
report on all the devices on your 1394 bus. However, bear in mind, that the
ohci1394 rom always reports a specific TI ohci chipset that is currently
hardcoded. We are considering alternative means for a proper description.
