- // Description : Peer to Peer Video Conferencing over the LAN.
- // Author : Nagareshwar Y Talekar ( nsry2002@yahoo.co.in)
- // Date : 15-6-2004.
- //
- // 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.
- //
- //
- // File description :
- // Name : Tmndec.h
- // Details : Main entry point for decoder.
- //
- // Usage :
- // 1) InitH263Decoder
- // 2) Invoke DecompressFrame with parameters
- // compressed data and output data pointers.
- // Note > Output data must be large enough to hold RGB data.
- // > Change the DecompressFrame function if you want
- // output in YUV420 format only. Just comment out conversion routine
- // 3) Repeat the step 2 for each compressed frame , for exit do 4
- // 4) ExitH263Decoder .
