Access to microphone and webcam

Question

Hi,
I need to access to microphone and webcam with Alchemy,
writing c/c++ code.
I know that is possible in ActionScript using classes Camera
(flash.media.Camera) e Microphone (flash.media.Microphone), but is
it possible also in Alchemy?
Can you help me?
Thanks in advance,
Amsicora

It sounds like you're porting an existing C application.
At a high level you need to modify the codebase so it plays
nicely in the Flash sandbox. Remember, the end result of your
Alchemy project is a Flash application, so you'll need to remove
all platform-specific code.
This means eliminating your application's dependence on the
Windows API. Rewrite any dependencies to access system resources in
a flash-friendly way.
If StartCamera is the only function that depends on the
Windows API, then remove windows.h and rewrite the body of that
function. To provide the necessary camera functionality you could
call out to a static AS3 method or write the logic in C. (See
snippet below.)

The following code creates a ByteArray. You could use a
similar approach to get a reference to Camera.
// Create a ByteArray in C
AS3_Val buffer_NS = AS3_String("flash.utils");
AS3_Val buffer_class = AS3_NSGetS(buffer_NS, "ByteArray");
AS3_Val buffer_array = AS3_New(buffer_class, AS3_Array(""));
AS3_Release(buffer_NS);
AS3_Release(buffer_class);
