I've noticed that components from the 4.5 source code release in the folder "v4.1/Product/Build/Screencaster" are only available in binary form. What is the license of theses extensions ?
BTW, you don't deliver your source code with a copy of the GPLv3 license so it's not clear which parts are GPL, which parts are from other open-source products (red5, libcurl, tomcat, ...).
I think I have the answer to my own question. The source seem available in Components/objc/Publisher (Mac OS X) and Components/cpp/Publisher (Windows). It seem that only the DFMirage driver is not available since it's not DimDim property (but you can download it there http://www.demoforge.com/dfmirage.htm\). But I haven't verified it by myself since I can't compile Apple Xcode nor Windows Visual C++ project right now.
