Video mixer is a small daemon written in c++. It combines multiple video streams into one. For example, four input streams stm1, stm2, stm3, stm4 may be combined into one who looks like:

+----------------+
| +----+  +----+ |
| |stm1|  |stm2| |
| +----+  +----+ |
|                |
| +----+  +----+ |
| |stm3|  |stm4| |
| +----+  +----+ |
+----------------+

Note that both the GStreamer & Qt must be built with exactly the same version of the MSVC. For example, if GStreamer is build with MSVC 2010, the Qt version should must be any from 5.0 till 5.5.
