- // I have converted origional fast h.263 encoder library from C to C++
- // so that it can be integrated into any windows application easily.
- // I have removed some of unnecessary codes/files from the
- // fast h263 library.Also moved definitions and declarations
- // in their proper .h and .cpp files.
