I've just bought some more Hauppauge cards, and of course they've changed
the design since I last bought one a few weeks ago - they now have the
Bt878 on them (Hauppauge model 61314). Since I'm running
FreeBSD-2.2-stable on these systems, the new cards weren't supported.
I have updated to the -current versions of:
sys/pci/{brooktree848.c,brktree_reg.h}
sys/i386/include/ioctl_bt848.h
and with a few minor hacks to make it compile in a 2.2 kernel, this driver
still works fine with an old 848 card, and it recognizes the new cards as:
bktr1 <BrookTree 878> rev 2 int a irq 10 on pci0:15:0
Hauppauge WinCast/TV, Philips PAL I tuner.
pci0:15:1: vendor=0x109e, device=0x0878, class=multimedia (misc) int a irq
10 [no driver assigned]
Unfortunately, it doesn't appear to work quite right when I test it with
FXTV. If configured for PAL (either "fxtv -driverDefaults" or explictly
by "fxtv -inputFormat pal") the picture is grossly out of horizontal sync
- you can roughly make out 4 copies of the picture sideways across the
screen. However, if you select NTSC mode (still feeding the card from a
PAL video source) you get a reasonable picture: no colour, and slightly
flickery at the top edge, but correctly positioned horizontally. This
behaviour in NTSC mode is probably what you would expect (625/50 and
525/50 having approximately the same line rate), but what has gone wrong
with PAL mode?
This card also gives the problem that only the tuner and S-Video inputs
appear to work - selecting composite video in just gives a blank screen -
but this is presumably just that FXTV needs updating to know about the 4th
multiplexor input.
Of course it is possible that I've fouled things up in hacking the
-current driver into a 2.2 system, but I don't think so given that the
hacks are minor and it still works perfectly in PAL mode with an 848 card.

Andrew Gordon.
