I switched when the PXC drivers had compilation troubles, but V4L worked. By "more modern" I mean the ones that lspci -v identifies as Brooktree Corporation Bt878 Video Capture (rev 11) I also have a Brooktree Corporation Bt848 Video Capture (rev 12) that V4L does not successfully capture. I have not pursued the issue since all the ones I have used in the field are Bt878 cards. My V4L code is not very generic, but could be a help in getting you started. I'm happy to share. Contact me directly for a tarball. Alessandro, I still used PXC on a 2.2 kernel that has been running for over 10 years. I also have a 2.4 kernel that also still works. As I recall 2.6 did work well but broke when they did a massive kernel rework. I would suspect the latest attempts to remove uses of the Big Kernel Lock may also need addressing. I am still very appreciative of all you have done for us here. I remember you not being happy with V4L some time ago. Is that still your feeling? I'd be curious to know why. Maybe we could have a direct conversation some time? Again, many thanks. -- Mike Bianchi Foveal Systems 973 822-2085 MBianchi@Foveal.com http://www.AutoAuditorium.com http://www.FovealMounts.com
