分享C#音视频采集,屏幕录制和混音录制的源码

播放器的搭建和操作，精美播放器界面设置...............(Build and operate the player, fine player interface settings )

Simple bare bones DLL to enumerate video capture devices, and capture into a buffer on a seperate thread. A program can link to this DLL, begin video capture, and pull from the 30 frames / second buffer at any frequency and get full RGB frames to then save to disk, encode, etc.(Simple bare bones DLL to enumerate video capture devices, and capture into a buffer on a seperate thread.

说明：  使用ffmpeg做的播放器。SDL处理音频，ffmpeg处理编解码音视频文件，qt做ui界面。使用多线程双缓冲队列播放音视频。使用视频追逐音频的策略实现音视频同步。支持视频镜像操作，黑白彩色转换。(A player made of ffmpeg. SDL processes audio, ffmpeg processes codec audio and video files, QT is the UI interface. Use multi-threaded double buffer queue to play audio and video. The strategy of video chasing audio is used to realize audio and video synchronization. Support video image operation, black and white color conversion.)

做一频谱分析处理，为滤波提供频率(Spectrum analyzer to do one deal, in order to provide frequency filtering)

【实例简介】C# 视频监控系统

本程序代码是在MSSG MPEG2Decode的基础上开发的，添加了如下功能 GUI界面,VFAPI支持,MMX优化等功能。 (The program code is developed in MSSG MPEG2Decode based on, add the following functional GUI interface, VFAPI support, MMX optimization function.)

EM8471神龙卡源代码,支持MPEG4,AVI等硬件格式播放.(EM8471 SHENLONG card source code, support for MPEG4, AVI format players and other hardware.)

语音识别，通过说话转化为语音。适合开发语音软件(good it‘s so worth that you must have a look)

学习dshow的好书籍，，即提高英文水平，也提高编程水平(learning dshow good books, that the standard of English, it also raises the level of programming)

仿REALONE窗体制作的播放器，后面会陆续制作其他窗体的播放器(imitation REALONE Form produced by the players, would be produced behind other windows player)
