I am running motion-3.2.4_snap4  under FreeBSD 5.3 


to answer your question 

under FreeBSD the SPCA5xx "driver" is not really system "driver" but I port of the Linux driver
to work as a user process using the generic USB device interface.

thus the motion application  will not be able to access a "video device" since there really
is not one.


But your in luck....

Since I have a USB cam that used the SPCA5xx driver port I did some
hacking to get motion to use it.  I did this by having motion to
exec and run  sub process as a "netcam" video source, then I modified
spca5shot that was to output a HTTP style MJPEG.

I got the basics  working but there are problems with the driver and white balance
as well always returning a 640x480 image.

thus this is not ready for prime time..  but is does sorta work

if you have spca5shot version 20050206 download my patches from

	http://www.lavrsen.dk/twiki/bin/view/Motion/ExecProxyPatch

apply the spca5shot diff or just replace spca5shot.c with the included version.

copy spca5shot to /usr/local/bin and link it to /usr/local/sbin/spca5stream  ( the app will now automaticly stream MJPEG if named spca5stream )

apply my proxy_exec patch to motion and recompile and install

in your motion config file place:

netcam_proxy exec://localhost/usr/local/sbin/spca5stream
netcam_url http://127.0.0.1:80/dev/null

where the netcam_proxy property is exec://<IGNORED_HOSTNAME>/path/to/spca5steam
netcam_url required although ignored (in this case)

since most people run Linux and this is a FreeBSD hack/issue
question email me directly off list  and I see what I can do for you.

I will summerize to this list or on the website when things are more stable.
