RIght now I'm working on a patch so I can use my webcam under wine
without having to switch to unix or use non-working solutions..
Right now there are 2 patches needed to get MSN to connect to the
internet: first is to disable SSL, second strcpy's a value at urlmon
getuseragent or something
To get this to work, a few modifications to existing files are needed:
First of all, if the catagory exists, let devenum return all from
videoinput catagory:

I wanted to put all custom code into qcap, but because of the pins
that's not possible.
I wrote a basic stub for CaptureGraphBuilder and added it and regsvr
calls to qcap.
There s no current implementation of qcap, so therefore I added my
gzipped qcap.tgz as an attachment (To keep things simple)
My current implementation of the actual interface was based on
filesource.c, so i made some functions and struct defs global in quartz:

As you can see here, a VfwCapture class is being created
to use it, we must register it and qcap with regsvr32

Before you think 'yey i can use a webcam now', I have to warn you, you won't
What did is made from figuring out what MSN did at every step, for this
to work and keeping it debuggable I ONLY used builtin dlls
minimum required overrides in wine config:
"quartz" = "builtin";FUCKING WORK!!!!
"amstream" = "builtin"
"qcap" = "builtin";You go girl.....
"ole32" = "builtin";Not really needed, but makes debugging easier
Currently this is NOT working, and MSN crashes for a reason I do not
understand,
Iif you want to help me continue working on webcam support i would
greatly appreciate it if you could help me pinpoint the source of the
crash..
WINEDEBUG=+quartz,+qcap is recommended.. and for now I'm only
Currently the code mostly exists out of ugly hacks, what I was working
on before msn crashed were the video formats (IKSPropertySet and
IAMStreamConfig capabilities), if someone can help me figure out why and
were it crashes, I could continue on my webcam project :=). You could
try to get it to work through 'Extra' 'Configure webcam' (Or something
like that, since I'm using Dutch version), and it crashes for a reason
unknown to me..
PS: I accidentally deleted my first patch file, you need to add
IAMStreamConfig and perhaps some other class into the include/*.idl
files, I'll release a patch when I'm at least 1% awake again :/
