- // This is the modified version of tmndecode (H.263 decoder)
- // written by Karl & Robert.It was in ANSI C. I have converted into C++
- // so that it can be integrated into any windows application. I have
- // removed some of the files which had display and file storing
- // functions.I have removed the unnecessary code and also added some
- // new files..
- // Original library dealt with files. Input & Output , both were files.
- // I have done some major changes so that it can be used for real time
- // decoding process. Now one can use this library for decoding H263 frames.
