Evostream server’s configuration for rtmps test Add the following content in the acceptors part in config.lua. This is for Win7 configuration and remember that we have to use double ‘' instead of single for path. The cipherSuite parameter, we could reference http://www.openssl.org/docs/apps/ciphers.html#CIPHER_SUITE_NAMES RTMP library The library is main from rtmpdump. The webpage is http://rtmpdump.mplayerhq.hu. The libssl library - SSLv23 method is used in the RTMPdump. - SSLv23 method A TLS/SSL connection established with these methods will understand the SSLv2, SSLv3, and TLSv1 protocol. ...

There is a new sensor structure that introduce by Panasonic to replace color filter by color splitter. This kind of sensor remove general color filter and add the color deflector before the diode. The conventional color filter would cause 50%~70% light loss and new sensor reduce lots of the light loss. The following pictures show how it works. The device can also be manufactured using current semiconductor fabrication processes. It doesn’t use special materials or processes. It’s a great news to bring this sensor to realization. ...

I’ve search on internet and get quick steps for whole process to generate Makefile by Autotools. autoscan . // scan the folder cp configure.scan configure.ac // copy the configure.scan to configure.ac vi configure.ac // edit the configure.ac // add AM_INIT_AUTOMAKE(hello,1.0) in configure.ac // this is required marco for automake aclocal // execute aclocal to generate aclocal.m4 autoconf // execute autoconf to generate configure autoheader automake –add-missing // run automake touch NEWS; touch README; touch AUTHORS; touch ChangeLog // create related documents automake –add-missing // run automake again ./configure // execute the configure to generate Makefile make // execute make According to the steps, I get more hint to modify the related files for my target.

I start to move the gstreamer version from 0.10.x to 1.0.x in openwrt. Two purpose, one is to get much more familiar with the gstreamer applications and plugins development, another one is to assist my colleagues for next schedule. Just make a quick note here. Official gstreamer packages version I use is 1.0.5: gstreamer core -> Modify Makefile and patch, compile ok. - gst-plugins-base -> Modify Makefile and patch, compile ok. ...

In previous articles, I tried to build the pjsip package, but it’s hard for me to make sure the package is work correctly because of my lacking knowledge of sip. Then I try to be more familiar with how the sip works. First, prepare a PC and install the switch on it. We have two popular choices, one is Asterisk and another one is Freeswitch. I choose the Freeswitch because there is a precompiled binaries for win7 already. ...

Before trying to make the pjsip work on my embedded device, I build the related libraries on PC as the reference. My environment is based Ubuntu 10.04. See the following guide. http://trac.pjsip.org/repos/wiki/Getting-Started/Autoconf The notes of packages building: - ALSA and OpenSSL libraries are optional and I do not install for first. - SDL, I download the version 2.0 and do “./configure”, “make; make install” to install the package to system. If we encounter privilege problem, please add sudo. ...

There is a default pjsip package in the openwrt but it link to the extension package of ltq-tapi and oss. But what I need first is the package without extra packages. So I try to create the libraries by using the latest version 2.1 for the experiment. First, the Makefile of the package as following. Makefile of the package. include $(TOPDIR)/rules.mk PKG_NAME:=pjsip2 PKG_VERSION:=2.1 PKG_RELEASE:=0 PKG_SOURCE:=pjproject-$(PKG_VERSION).tar.bz2 PKG_SOURCE_URL:=http://www.pjsip.org/release/$(PKG_VERSION)/ PKG_MD5SUM:=310eb63638dac93095f6a1fc8ee1f578 PKG_INSTALL:=1 PKG_BUILD_PARALLEL:=1 PKG_BUILD_DIR:=$(BUILD_DIR)/pjproject-$(PKG_VERSION).$(PKG_RELEASE) ...

I’ve already change my tool from the notepad++ or Microsoft’s word to Evernote to make a quick note for several months. It’s quite simple to use and the data can be synchronize to cloud and I could access my notes through network everywhere anytime. There is a news that Samsung’s refrigerator built in Evernote for food management and Samsung show this device in the CES show. The story at this moment, I think Evernote make his products go into a new era. However, the morning sun never lasts a day. Evernote was hacked and the customers information were possibly stolen last week. ...
