There is a module that gets made with libavc1394 called dc1394_vloopback
http://sourceforge.net/projects/libavc1394/ When you install it it gets put in usr/local/bin
It enables you to use vloopback module http://www.tibit.org/video/vloopback-0.90-tibit.tar.gz
as a v4l device. There are no docs with it but if you open the program in a text editor it gives you the user parameters. I haven't used it yet Let me know if it works. The author wrote it to use a dv camcorder with effectv.

If no drivers are there now (and I don't think there are), is it even possible to write a v4l driver to support this?No, and this likely never happens. It should be possible to write a driver with v4l2 API, but that will give you dv compressed frames, i.e. some app expecting to receive frames in RGB format will not work.But what about a v4l driver for Digital Camera format (uncompressed video over firewire); I'd assume it should be very easy to develop. Has it already been implemented? Actually, I remember somebody on this list saying they were working on a v4l2 driver for DFG/1394 by Source Imaging -- which is, as I understand, a standard Digital Camera device, so their driver would probably work with any such device. Has any progress on that project been reported? Another question still, are there any digital video frame grabbers supported by v4l? (by that I mean a framegrabber that supports any digital video format LVDS, RS-422, firewire etc.) Thank you very much, any info is very much appreciated. -L. -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request@xxxxxxxxxx?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/video4linux-list
