[Wine]passing linux devices to a program in wine

[Maaike van der Locht]

Hi, i'm trying to find out if i could use my webcam in
Netmeeting. I can receive video, but am not able to
send because wine can't handle this yet. So I'm doing
a little "research":

When I run Netmeeting in normal windows with depndency
walker i see this:


LoadLibraryExA("C:\Program
Files\31Netmeeting\dcap32.dll", 0x00000000,
LOAD_WITH_ALTERED_SEARCH_PATH) returned 0x6C000000 by

Apparently dcap32.dll ( a dll belonging to Netmeeting)
takes care of the capturing video api's (no avicap32
is used). My question is: could it be somehow possible
in wine to pass my /dev/video to this dll so that it
would be recognized as the capture device and how
could this be done? Or could it be possible to write a
"fake" dcap32 which would do the trick(i just started
learning c-programming right now)Any hints /pointers
welcome.
