grab video under linux

移植了ffmpeg库，实现H.264视频的编码，rtsp的实时交互。网络是通过udp传输，RTP解包h.264解码，在android平台上实时播放。

Android视频加密，加密速度快，而且提供登陆密码功能。

可以进行视频捕捉,为很好的视频捕捉程序 -can capture video for a good video capture process

实验中发现opencv的cvCaptureFromCAM 使用的是vfw,采用消息机制,速度较慢,测试发现fps只有 9-12左右,太慢了. 发现经过使用directshow后速度提升到60帧/s.在opencv group上了解到这是一个普遍问题,也许有人做过转换,却没有完整的例子与代码.在此贴出.对希望提高opencv视频分析速度的有所帮助-Opencv experiment found that the cvCaptureFromCAM using vfw, the use of information mechanism to slow fps test found that only about 9-12, too slow. Discovered through the use of DirectShow velocity to 60/s. In opencv group understanding that this is a common problem, perhaps someone has done the conversion, but no complete examples and code.此贴out in. opencv want to improve the speed of video analysis help

DIRECTSHOW的捕获程序的简单实现-DirectShow capture a simple process to achieve

基于Emgu的是背景建模，使用VS2010+Emgu2.3.0环境，亦可导入摄像机数据，使用EM算法对单独像素点的出现在时间方向上的累加进行建模的方法是新颖的，并且对一个典型的确定的方法提供了一种自然的概率层面的概括

利用Visual C++ 6.0开发工具实现的摄像头采集程序。对于普通usb摄像头通用。可以直接用于视频项目中。-The use of Visual C++ 6.0 development tools to achieve the camera acquisition program. For ordinary usb camera generic. Can be directly used for video projects.

创建了基于中自科技嘉的OK采集卡的采集平台，创建了采集类，并独立设计出相关的DIB类和DIBShow类配合采集类显示图像和其他操作使用，个人感觉设计思路具有采集卡程序设计的通用性，开发平台是VC6.0，硬件环境OKC30采集卡，欢迎大家批评指正，提出更好的设计方案-created based on the technology since Stoker"s OK acquisition card collection platform, creating a collection category, and independent design DIB related to the type and category DIBShow with Caudio display pictures and other operational use, personal feeling Design Capture Card with a common program design, development platform is VC6.0 , the hardware environment OKC30 acquisition cards, we welcome criticism correction and provide better design

通过普通USB接口的网络摄像头进行视频图像采集，并可以完成AVI格式的视频录像。加上音频采集和音视频同步机制会更好。-by ordinary USB Webcam Video image acquisition, and will be completed AVI format video projection. Audio acquisition and add audio and video synchronization mechanism will be even better.
