是否可以拍摄图像（或图像序列）并将其作为硬件设备（网络摄像头）使用C ++ / OpenFrameworks传递给Mac OSX？

Question

Pretty new to oF and C++, but trying to open up communications between Flash (AS3) and a Canon DSLR. We've successfully done it using a socket server (using https://github.com/roxlu/ofxFlashCommunication ), so AS3 can trigger the DSLR's shutter, get the image path, etc. But we want to turn the live view preview (which is easy to view in the C++ app using Canon's SDK) into a webcam stream so that Flash can display a preview (via AS3's native Camera and Video classes) to the user. Unfortunately, passing the live view image data through the socket server is not an option as that requires converting the image to a byte array, passing it to flash, and having flash parse that back into an image. That method was way too slow (low FPS).

Current OS: Mac OSX 10.8.3

What is the best way to get the live view from C++ to Flash? Is there an easy to use library for oF/C++ that can help me turn a sequence of images (in real time) to a native hardware webcam stream?

There is a soft that can open a Canon DSLR and turn into an AS3 native camera http://sparkosoft.com/

Unfortunately it doesn't seem to respect the frame rate settings on the cam. I don't know if theres is a hardware limitation which wouldn't allow for 60fps.

Maybe this will get you closer to where you want. If you're able to get it working @60fps let me know http://www.monday8am.com/en/2012/05/29/canoneos_lib_extension/
