|For a few months, I've been using my Hauppague Wincast/TV - fm Model 401 on |my 2.2.6-Release system to view/capture etc. cable TV. I use fxtv 0.46 from |ports but had to get the driver from |http://telepresence.dmem.strath.ac.uk/pub/bt848/22x |<http://telepresence.dmem.strath.ac.uk/pub/bt848/22x>; and patch it as |described there to work with a pre 3.0 system. TV is great at 800x600 16bpp |(usually) as well as higher resolutions and higher bpp. Ok. |I just bought a color camera to play with things like Mbone, NetMeeting etc. |When I use it with fxtv, the system locks up. At 640x480 8ppp, there is no |lockup, but the picture quality is lacking. At 16bpp FreeBSD locks. Under |NT 4.0 SP4, I run 800x600 true color to be sure the hardware works. | |Besides moving to a current version of FreeBSD, is there anything I can try |to figure out what is wrong? Hmm. What motherboard? And was this the same as what you had working on a pre-3.0 system? Does it work @ 24bpp? In 16bpp, try "fxtv -disableDirectV". See if that is stable. Basically, it's forcing the same transfer mechanism as is occuring in 8bpp (TV-card-to-system-memory copy, munge, then hand to X server to display), rather than the default in 15/16/24/32bpp modes which is direct video (TV-card-straight-to-video-card-frame-buffer transfer). |My system is 2.2.6 installed from CDROM. I run XF86 3.3.2 on a Matrox |Millennium II PCI with 8MB WRAM. My monitor is a Viewsonic 17. The Millenium 8MB. You'll probably need the 8MB millenium patch to work around an X server bug if you run > 1024 and @ 32bpp. Might try cranking the resolution up and see if that works any better.
