JAVA基于局域网的聊天室系统(源代码+论文)
基于局域网的视频聊天室系统的设计与实现摘 要视频聊天系统作为一种新型的通信和交流工具，突破了地域的限制，可以提供更为便捷、灵活、全面的音、视频信息的传递和服务，具有极其广泛的发展前景。本文介绍了采用JAVA编程开发视频聊天系统的一套比较常用的解决方案。文字聊天采用TCP模式；语音视频聊天采用UDP模式，在客户端之间点对点的进行。在该方案中，通过函数库VFW来实现视频捕获、影像压缩以及影像播放。微软公司提供的专门用于视频捕获开发的工具包VFW，为在Windows操作系统中实现视频捕获提供了标准的接口，从而大大降低了程序的开发难度。在视频传输方面，则通过组建视频帧，将位图形式的视频帧压缩成帧格式的Mpeg4流，传输到客户端后，解压并显示影像。同时，在本方案中，采用了线程来实现语音录制和语音回放，最终实现了通过服务器中转的文字聊天、点对点的语音视频聊天。 关键词：文字聊天；VFW；视频捕获；视频传输；语音录制；语音回放The Design and Realization of LAN-Based VideoChat Room SystemAbstractAs a new tool about communication, video chattingsystem has broken through geographical restrictions, has provides moreconvenient, flexible and complete transmission and service. Furthermore, it hasa very bright future.The common solution about how to develop a videochatting system is introduced by the Microsoft Visual C + + 6.0 programming.TCP model is used in the text chatting and UDP for the point-to-point videochats between the Clients. In this plan, Video Capture, Video Compression Managerand DrawDib are realized by the functions of VFW Library. The special kit VFW (Videofor Windows) in video capture offered by Microsoft Corporation, has provided astandard interface for video capture in Windows Operating System and thusgreatly reduced the hardship of programming. In video transmission aspect, it requiresa video frame which is compressed the video frame of bitmap into Mpeg4 steam offrame form. Then it will be decompressed into images since it has been arrivedthe Client. Meanwhile, the thread is used to achieve audio recording and replaying.Finally, it has realized the text chatting through a server to transit, thepoint-to-point audio and video chats.

楼主听话，快到碗里来！ 你有没有见过这么整齐的十五字啊 如果这就是爱，再转身的时候就该留下 如果这就是爱，再转身的时候就该留下 我只是挽尊的，貌似还不够十五字 如果你智商能再高点，也许我会上当 今天没吃药感觉自己萌萌哒 如果这就是爱，再转身的时候就该留下 楼主节操掉了，还不快捡起来
