New ONVIFPlayer lauched with ONVIF v1.0 & v2.0 supported

I once planned to upgrade my conditional open-sourced project RTSPPlayer(http://rg4.net/rtspplayer) to ONVIFPlayer, which requires a device with ONVIF protocol supported.
However after resigned from UniSVR, I didn't have the oppotunity to access any ONVIF devices.
Lucky me, I got one from one of my former colleague days before, DAEWOO 570C-X10S (79), which is with both ONVIF v1.0 & v2.0 supported. So today I got my ass down before my laptop, and make some improvement for my ONVIFPlayer App.

Extend your H.323-based applications by using NON-STANDARD messages

Extend your H.323-based applications by using NON-STANDARD messages

Abstract

Comparing to SIP protocol or RTSP protocol, H.323 protocol is a strict one, which has its own working flow control, and every bits in it's protocol buf has its meaning. However H.323 provided a NON-STANDARD message machenism to allow users to extend your own bussiness rules. This document is discribing a example extended H.323 bussiness by using NON-STANDARD message of H.323. And also could be a guide of how to start your own NON-STANDARD message for your H.323-based applications.

Keywords: H.323, RAS, NON-STANDARD message Continue reading “Extend your H.323-based applications by using NON-STANDARD messages”

人体运动目标的检测与跟踪

人体运动目标的检测与跟踪技术是计算机视觉的主要研究方向之一,在生物医学,人机交互,虚拟现实,智能安全监控,机器人技术,图像压缩,计算机图形学等领域都有着广泛的应用。

运动目标的检测就是从视频流中去除静止的背景,检测出运动的目标及携带的运动信息,运动目标的检测对跟踪等后期处理非常关键[1]。目前,运动目标的检测方法主要有四种:背景差分法、帧间差分法、光流法、基于特征的方法。

现有的目标跟踪方法主要有两类:一类是基于相关的目标跟踪。这是一种先检测后跟踪的方法,它适用于目标之间相互作用较小和背景较简单的情况 ;另一类是基于特征的目标跟踪。这是一种先跟踪后检测的方法,跟踪的结果需要检测来校正[2]。 Continue reading “人体运动目标的检测与跟踪”

VS 2008 debug error: Binary was not build with debug information

One of my VS2008 Project can not run debug, however the output windows will trace out a message like this, “Binary was not build with debug information”, when I try  run this project in debug mode.

The problem is, as the error message suggests, you have not built your project with debug information.

To fix this issue, all you need to do are:

  • Goto Project->Properties
  • Select “C/C++”, then “General”
  • Make sure set the project configuration of “Debug information format” to “Program Database for edit and continue (/ZI)”
  • “C/C++” –> “Optimization”
  • Make sure set the project configuration of “Optimization” to “Disabled (/Od)”
  • “C/C++” –> “Code Generation”
  • Make sure set the project configuration of “Runtime library” to “Multi-Threaded Debug (/MTd)”
  • “Linker” –> “Debugging”
  • Make sure set the project configuration of “Generate Debug info” to “Yes (/DEBUG)”

If everying is confirmed or done, try rebuild your project, and run debug again, enjoy your debug.
