One of my EasyIV project’s featured function is face detect, but obviously it was only used to collect faces for further process, like face recognition, of some other application or system working along with EasyIV. I’d say here, face recognition was also included in my plan for EasyIV. However, after […]

New release of EasyRTMP
3 Just confirmed that my VPS supports nginx and rtmp yesterday, so I went and digged out my ancient code of EasyRTMP, tried to re-compile it. Codes of DVR & RTP streams relay mode are lost in my previous disaster of hard disk broken at last year which caused the lost […]

Days ago, I reinstalled nginx + nginx-rtmp-module on my notebook, and had it tested in my local environment with firefox and VLC player, made sure it worked(You can refer to this post for guide: http://rg4.net/archives/1414.html). However, when I tried to redo the working on my VPS, only to find that […]
[RTMP]JWPLAYER: Could not connect to server
1 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 […]
New ONVIFPlayer lauched with ONVIF v1.0 & v2.0 supported
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]。

The old version of RTSPPlayer was using ffmpeg + SurfaceView + RGB565 mode to decode and render the video. However this implement is definitely a sucked one, especially when watch high quality videos. So I made some change for it. And the new solution is HW decode + GLSurfaceView + […]

2 ↑ Introduction Streaming relays and reflectors can be used to scale streaming infrastructure by distributing load between servers and making the most efficient use of network bandwidth. A streaming reflector “tunes in” on and incoming stream and relfects it to clients. The most common setup for a reflector is reflecting […]

There was a bug in RTSPPlayer, that is when you poll down the preset RTSP stream source list spinner, the APP will crash with an NullPointerException. Today, I finally have it fixed.
NullPointerException error when polling down the preset url list spinner
Because most of the public online RTSP streaming source are no long availible now, so I decided to remove most of the preset RTSP streaming sources, change to a configurable user input xml(saved in /mnt/sdcard/RG4.NET/RTSPPlayer/RTSPPlayer.xml). And from now on, RTSPPlayer will start to support ONVIF devices. I will also change […]
