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
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

视频编解码器
应用背景
This is the second public release of our MPEG-2
encoder. It converts an
ordered set of uncompressed input
pictures into a compressed bitstream
compliant with ISO/IEC 13818-2 DIS [1]
(MPEG-2).
This program will evolve to become:
ISO/IEC 13818-5 Software Simulation
of MPEG-2 Systems, Video, and Audio.
关键技术
The execution
template for the encoder is:
mpeg2encode parameter_file
output.m2v
Coding parameters can be modified by
editing the parameter_file. Since the
parser expects the operating parameters
to be on certain line numbers,
kindly do not insert or delete lines
from the file.
We have provided a couple of sample
parameter files in the par directory.

视频—镜头切换检测，关键帧提取
检测视频中镜头切换的关键帧 检测镜头切换的基本思想是：对比视频中前后两帧灰度差，若两帧差值超过阈值，则说明视频中的镜头转换了，并把这一帧作为关键帧保存下来。 定义相应的指针和结构 初始化指针和结构 计算视频中前后两帧的灰度差 将两帧的灰度差值与阈值比较，超过阈值，则将其判定为关键帧保存 其中阈值大小根据视频的情况进行调整
