H.323的PWLib代码

ITU-T编写的h.263协议文档，相当权威！对做视频编码解码有帮助！-ITU-T H.263 agreement prepared by the document, rather authoritative! Done right video codec help!

利用h.323进行语音呼叫的程序-use H.323 voice calls for the procedure

视频音频处理演示文件，其中视频编解码包括XVID，H263P和H264，音频采用ILBC，音频做了AEC处理。-demonstration video audio processing documents, which include video codec XVID, H263P and H264, used ILBC audio, audio processing done by the AEC.

分网络传输部分、音频输入、音频输出、视频输入、视频输出、音频视频压缩、音频波形显示、界面。共创建个线程，音频输入线程、音频输出线程（这两个有WINAPI隐式创建）、音频视频压缩传送线程和主线程。因为音频的采样率比视频采样率高得多，这里的音频的采样率为8000Hz而视频仅为20左右，所以从宏观来看，音频是连续的，而视频是非连续的，这也就是无须为视频输入输出创建独立线程的原因。- Minute network transmission part, audio frequency input, audio frequency output, video input, video output, audio frequency video frequency compression, audio frequency profile demonstration, contact surface. Altogether founds the line regulation, the audio frequency input line regulation, the audio frequency output line regulation (these two has WINAPI to hide type to found), the audio frequency video frequency compression transmission line regulation and the master line regulation. Because the audio frequency sampling rate is much higher than the video frequency sampling rate, here audio frequency sampling rate is 8000Hz but the video frequency is only about 20, therefore from macroscopic looked, the audio frequency is continual, but video frequency right and wrong continual, this also
