Video Subtitle Encoder Module / (optional) DirectShow

Create a subtitle encoder according to DVB / ETSI EN 300 743 Input: Bitmap Data RGB32 with subtitle mask and blank background Output: Subtitle binary data "bitmap encoded" compatible to DVB The Subtitle data later needs to be multiplexed into a MPEG Transport Stream. The multiplex is not part of this project request, only Bitmap->Subtitle Programming in C/C++ for Windows, VisualStudio2008 Clean API with a C Level Function Interface, for example CreateSubtitleFromBitmap(InputBitmap, OutputData) The surrounding architecture is DirectShow. This project does not need to use DirectShow, the simple C API would be enough. DirectShow know-how is a benefit for optional additional work. Delivery should include a simple command line test application including full source code.
