Great news from Cisco: Cisco will open open-source their H.264 codec, and make H.264 free for use in WebRTC. Here are the details, which came from blogs of Cisco by Rowan Trollope: ——————————————— When it comes to making collaboration technology such as high-definition video open and broadly available, it’s clear […]

Open-Sourced H.264 Removes Barriers to WebRTC

WebRTC Voice Engine - AGC control workflow 2
Introduction of this document This module includes software based acoustic echo cancellation (AEC), automatic gain control (AGC), noise reduction, noise suppression and hardware access and control across multiple platforms. My ultimate goal will be wrapping an independent module out of WebRTC’s Voice Engine for our product, and the first task […]

First week in the new company

1. 下载安装svn客户端,例如TortoiseSVN。安装完后,svn执行目录自动被添加入系统环境变量PATH中。 2. 下载并安装msysgit和Tortoisegit msysgit下载地址:http://code.google.com/p/msysgit/downloads/list Tortoisegit下载地址:http://code.google.com/p/tortoisegit/downloads/list 选择适合自己系统的版本,下载并安装(注:Tortoisegit只是一个gui,必须安装msysgit) Tortoisegit安装时会找到git目录并自动配置好。把msysgit中bin目录手动添加到系统环境变量PATH中,比如我的目录是“D:/Program Files/Git/bin” 3. 下载并安装Python,建议安装Python2.6 下载地址:http://www.python.org/download/releases/2.6/。安装后Python执行目录自动被添加入系统环境变量PATH中。 4. 下载并配置depot_tools     建立一个存放depot_tools的目录,command进入该目录     svn co http://src.chromium.org/svn/trunk/tools/depot_tools     下载后把depot_tools目录手动添加到系统环境变量PATH中 5. 建立WebRTC的源码目录     比如E:/Developer/WebRTC/ 6. 打开cmd,进入第5步建立的源码目录 7. 执行:  gclient config https://webrtc.googlecode.com/svn/trunk         或者 gclient.bat config https://webrtc.googlecode.com/svn/trunk 8. 执行:  gclient sync –force (注意这里是两个- […]
