Hi wengophone hackers,

I saw there was a discussion to use the unicap library for your project. Since I am the developer of this library I thought I should give some explanations to some issues that came up on this thread:
http://thread.gmane.org/gmane.comp.voip.wengophone.devel/287

The first issue was the lack of CVS. I admit this situation is not too good. On the other hand I thought that working with the CVS repository is only an issue for people who also want to develop on the unicap library itself. I think users ( and projects using the library ) are better of with the .tar.gz releases since the ought to be tested by me in some way.

Of course if there is really a demand for CVS, I could reconsidder using it again ( especially when sourceforge comes around to use SVN which should work even better for me ).

The next issue is the lack of documentation and I admit it is a problem. I have this on the list but the main goal of this library is to keep it as simple as possible so there should not be a problem in understanding the API.

To the question whether the project is still active: It is indeed active. I work for a company called The Imaging Source ( www.1394imaging.com ) which manufactures digital imaging devices ( mostly for industrial/scientific/medical applications ) and unicap is propagated by them as the Linux API for all of their devices. Actually unicap is the only way to use some of their devices.

Currently unicap works best for IEEE-1394 ( firewire ) devices and it is known to work with bt878 based ( video-4-linux-2 driven ) frame grabbers and several video-4-linux webcams. However since I do not have a video-4-linux device that works on my laptop anymore, I would be very interested in any test results regarding video-4-linux devices.

All the best,

 /Arne
