Kenneth P. Stox:
|I currently have the Hauppauge WinCast/TV working with Amancio's bt848
|driver. It works great. I can select from different sources, ie. Tuner or
|video in, but I have no control over the tuner. When I get the time, I
|hope to be able to get the info from Hauppauge and/or their chip vendor on
|how to program the tuner. It should be pretty simple, but I haven't done
|it yet, so it is an open question.
|
|BTW, this is running under 3.0-current.
Sounds good. Say, I was reading-up on the Hauppauge board last night and
it looks promising. It says it does DMA transfer straight from the Wincast
to the video board, with scaling taking place on the Wincast or video board
depending on the video board's capabilities. Which brings up my main
question:
Under FreeBSD (with your driver, Amancio), what are the requirements on the
video board for the Wincast (DMA transfer, etc.) to work? Are there any
other potential gotchas I should look out for (e.g. what is "PCI Push"
capability in the Hauppauge lingo? Memory aperture support?). In
particular, I'm interested as to whether I can use this with my Hercules
Stingray 64/Video 2M PCI.
Also, I'm interested in getting some programming specs for this board
(tuner, digitizer, etc.). I've got mail out to Hauppauge, but if you have
a line on this already, I'd appreciate any pointers you could give.
Thanks,
Randall
