Hi
When I use the bt848, I normally build it as modules. To use it you need
then videodev, i2c and bttv modules.
Looking through the config there does not seem to be any option for i2c
support. I would suggest trying as a module unless anyone else knows how to
include i2c support as standard.

I got the tools from the tools from the BTTV home page at
http://www.thp.Uni-Koeln.DE/~rjkm/linux/bttv.html
The main one I got was the standard bttv distribution, though you need to be
careful with that. It includes its own drivers and they are different to the
ones in the kernel. I think Alan Cox has taken over control of these drivers
as they are more compatible with the video4linux stuff.
I am also working on my own capturing program if you are interested, though
it currently only captures single images (late last night).

xawtv, at http://user.cs.tu-berlin.de/~kraxel/linux/index.html
allows you to watch, and take snapshots.
There's also FXTV, at http://multiverse.com/~rhh/fxtv/
which is only for BSD, but does MPEG conversion on-the-fly.
It'd be nice if it could be ported to Linux. I think the kernel driver might
need some modification to support the continuous grabbing.

Ralph Metzger and Gerd Knorr do all the hard work on this driver. I merely
collect it up for kernel bundling impose a bit of CodingStyle and try
and turn any hardware specific stuff Ralph invents into extensions of
the generic API.
Credit where due.. I just shuffle ioctls around

The current driver supports mmap to two buffers with synchronization so
you shouldnt need any modifications at all

/me again. While talking about MPEG and stuff...
I have a small tcl/tk application which is supported to become a
video capture tool. It is neither comfortable nor very stable, but
can already do video recording (uncompressed avi, video+audio).
Hav'nt found much time for it last months, guess this will not change
in the future becauce I finished my study now...
I'll put my current code to
http://user.cs.tu-berlin.de/~kraxel/linux/grab-980420.tar.gz
within the next few minutes. If someone wants to take over or use the
code as starting point for another cool application, feel free...

I can do 25 fps here with bttv, no problem. Not rock-solid yet (have to
reload the driver from time to time), but basically it works.

What software do you use for it?
I don't like the idea of reloading the driver - about 50% of the time it
causes the entire system to hang when it's reloaded.

It seems that the current bttv driver (0.5.6) supports a mmap() system
call. I have tried to copy the video image to memory space from video
capture frame buffer by the mmap(). But I never success.
Please show me the neat code with mmap() to grab the image by bttv
driver.
I use a bttv capture card with VIC (Video Conference Tool) by old
bttv driver (0.4.3), which can grab the image by ioctl(). But the
function is obsolete.
Thanks in advance.

I have also found it hanging sometimes.
I am working on some simple frame capture software and while experimenting
with my software and xtvscreen that it would just lock up solid. I think
that was when I may have had the wrong frame buffer address :-) but I
couldn't be certain.
I also got some irq loop messages. Unfortunately I now have my software
working and don't seem to get these messages any more, but I sure that I
could break it again :-)

Now I can get the more than 30 fps video images (16bpp@640x480) into
the memory by mmap. I use PentiumII 300MHz PC with Bt848 Video Capture
Card.
BTW, I must call ioctl() with VIDIOCSFBUF before VIDIOCMCAPTURE.
I think that calling VIDIOCSFBUF is not necessary for using mmap.

I found that it has been fixed in kernel-2.1.105.
Thank you.
Now I can get the more than 30 fps video images (16bpp@640x480) into
the memory by User Mode :-).
