1. sip stacks
pjsip/bell-sip/sofia-sip/libeXosip/libre
https://github.com/staskobzar/sip_stacks_examples
2. sip user agent and server network architecture
3. Installing pjsip on Ubuntu
sudo apt-get install libasound2-dev
Linux system has two audio drivers: alsa and oss,oss is old,pjsip supports both,deflaut is oss.
如果目标系统内核使用的是alsa驱动,运行例子程序的时候会出现以下问题。
alsa_dev.c ! ca_thread_func: error reading data! 解决方法 修改config_site.h文件 在pjproject\pjlib\include\pj目录下
add #define PJMEDIA_AUDIO_DEV_HAS_ALSA 1
4. cross-compile
_install.sh
#compiler setup if [[ $1 = 'arm' ]]; then compiler=`CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++` host=arm-linux-gnueabihf elif [[ $1 = 'himix100' ]]; then compiler=`CC=arm-himix100-linux-gcc CXX=arm-himix100-linux-g++` host=arm-himix100-linux elif [[ $1 = 'himix200' ]]; then compiler=`CC=arm-himix200-linux-gcc CXX=arm-himix200-linux-g++` host=arm-himix200-linux else : fi #Preinstalled directory install=${HOME}/_install #Delete installed directory rm -rf ${install} #library path pkg_config=${install}/lib/pkgconfig lib_config=`CPPFLAGS=-I${install}/include CFLAGS=-I${install}/include LDFLAGS=-L${install}/lib` #Delete compiled directory for i in `ls .` do if [ -d $i ];then rm -rf $i fi done tar xvf alsa-lib-* cd alsa-lib-* ./configure ${compiler} --prefix=${install} --host=${host} make && make install cd .. tar xvf alsa-utils-* cd alsa-utils-* ./configure ${compiler} --prefix=${install} --host=${host} PKG_CONFIG_PATH=${pkg_config} ${lib_config} --enable-static --enable-shared --disable-alsamixer --disable-xmlto touch ./alsaconf/po/t-ja.gmo touch ./alsaconf/po/t-ru.gmo make && make install cd .. tar xvf pjproject-* cd pjproject-* ./configure ${compiler} --prefix=${install} --host=${host} PKG_CONFIG_PATH=${pkg_config} ${lib_config} --enable-static --enable-shared --disable-libwebrtc make dep make && make install cd .. export PATH=$PATH:${install}/bin export LD_LIBRARY_PATH=${install}/lib:$LD_LIBRARY_PATH export ALSA_CONFIG_PATH=${install}/share/alsa/alsa.conf

4)如果用的海思arm-himix200-linux-gcc编译器,如果报错的话,可能需要将
alsa-utils-1.1.9/alsamixer/alsa-utils-1.1.9/alsamixer/volume_mapping.c里的三行exp10改成exp
5)声卡设备验证
#查看音频设备
dong@dong-ubuntu:~$ arecord -l
**** CAPTURE 硬體裝置清單 ****

#录音
dong@dong-ubuntu:~$ arecord -D "plughw:0,0" -f S16_LE -r 16000 -d 5 -t wav file.wav
正在录音 WAVE 'file.wav' : Signed 16 bit Little Endian, 频率16000Hz, Mono
#播放录音文件
dong@dong-ubuntu:~$ aplay file.wav
正在播放 WAVE 'file.wav' : Signed 16 bit Little Endian, 频率16000Hz, Mono
一般alsa设置了一个defaults设备,音频播放软件默认使用defaults设备输出声音。defaults设备定义在alsa.conf中,内容如下:
[plain]
#
# defaults
#
# show all name hints also for definitions without hint {} section
defaults.namehint.showall off
# show just basic name hints
defaults.namehint.basic on
# show extended name hints
defaults.namehint.extended off
#
defaults.ctl.card 0
defaults.pcm.card 0
defaults.pcm.device 0
defaults.pcm.subdevice -1
……
defaults会默认匹配card number和device number比较小的声卡。
如果要修改,则修改/etc/asound.conf或~/.asoundrc。比如我要把defaults匹配到card 1,device 3上,则添加一下几行:
[plain]
$ sudo vim /etc/asound.conf
defaults.pcm.card 1
defaults.pcm.device 3
defaults.ctl.card 1
5) 添加声卡节点
if [ ! -d /dev/snd/ ]; then
echo "make snd node."
mkdir /dev/snd
ln -s /dev/pcmC0D0c /dev/snd/pcmC0D0c
ln -s /dev/pcmC0D0p /dev/snd/pcmC0D0p
ln -s /dev/timer /dev/snd/timer
ln -s /dev/controlC0 /dev/snd/controlC0
ln -s /dev/mixer /dev/snd/mixer
fi
5) 录音播音测试
arecord -D "plughw:0,0" -f S16_LE -r 16000 -d 5 -t wav file.wav
aplay file.wav
arecord -d 10 -f cd -r 8000 -c 2 -t wav test.wav
arecord -D "plughw:0,0" -f U16_LE -r 16000 -d 5 -t wav file.wav
arecord -d 10 -t raw -f S16_LE test.pcm
aplay -t raw -c 1 -f S16_LE -r 8000 test.pcm
arecord -d 10 -t raw -f U16_LE test.pcm
aplay -t raw -c 1 -f U16_LE -r 8000 test.pcm
arecord -d 10 -t raw -f U8 test.pcm
aplay -t raw -c 1 -f U8 -r 8000 test.pcm
aplay -t raw -r 8000 test.g711
arecord -D "plughw:0,0" -f U16_LE -r 16000 -d 5 -t wav file.wav
arecord -f S16_LE | aplay -f S16_LE
3、pjsua应用实例
pjsua Manual Page
https://www.pjsip.org/pjsua.htm
1) register --- make call
./pjsua-x86_64-unknown-linux-gnu --config-file paul.cfg
m
sip:[email protected]:5060
2) peer to peer
./pjsua-x86_64-unknown-linux-gnu --null-audio
./pjsua-x86_64-unknown-linux-gnu sip:120.78.180.208 --null-audio
3) register cli
>>> +a
Your SIP URL: (empty to cancel):sip:[email protected]:5060
URL of the registrar: (empty to cancel):sip:120.78.180.208:5060
Auth Realm: (empty to cancel): *
Auth Username: (empty to cancel): 100
Auth Password: (empty to cancel): 100
4) alice.cfg
# This is a comment in the config file.
--id sip:[email protected]:5060
--registrar sip:xx.xxx.xx.236:5060
--realm *
--username alice
--password secret
启动程序,自动应答
./pjsua-arm-unknown-linux-gnueabihf --config-file alice.cfg --auto-answer 200
指定“紧凑模式”(去掉SIP协议的一些非必须的字段),采样率和编码优先级,我在cortex-a5上以默认参数启动,会出现pb和ca线程不同步underrun!
./pjsua-arm-unknown-linux-gnueabihf --config-file alice.cfg --use-compact-form --clock-rate=8000 --add-codec=pcmu --auto-answer 200
其他配置参考官网应用手册https://www.pjsip.org/pjsua.htm
5) 临时建群,多方通话
查看pjsua应用手册https://www.pjsip.org/pjsua.htm
的Call Commands和Conference Commands
M |
Make multiple calls | Make multiple calls to the same destination. |
cl |
Conference List | List all the ports registered to the conference bridge, and show the interconnection among these ports. |
cc |
Conference Connect | Create a unidirectional connection between two ports. For example, if you have a WAV player connected at slot #1 and a call connected at slot #2, you can stream WAV file to the call by specifying this command: cc 1 2. |
cl查看已拨号的通道, 0是拨号的主叫号码本身,1和2分别是ringback和ring,3和4是被叫号码
M
2
sip:[email protected]:5060
sip:[email protected]:5060
cc 3 4
cc 4 3
6) freepbx语音会议
配置好freepbx语音会议后,直接拨号会议号,然后输入密码进入会议室
./pjsua-x86_64-unknown-linux-gnu --config-file 106.cfg --use-compact-form --clock-rate=8000 --add-codec=pcmu --auto-answer 200
也可以自动登陆会议室,auto-conf是自动登陆会议室
./pjsua-x86_64-unknown-linux-gnu --config-file 106.cfg --use-compact-form --clock-rate=8000 --add-codec=pcmu --auto-answer 200 --auto-conf sip:[email protected]:5060
PC/android/ios也是一样的操作
4、 py_pjsua应用实例
https://trac.pjsip.org/repos/wiki/Py_PJSUA
python实例在pjsip-apps/src/python/samples/
5、Python_SIP编译安装
1) ./configure CFLAGS='-O2 -fPIC' --enable-shared
https://trac.pjsip.org/repos/wiki/Python_SIP/Build_Install
2) pjsua2安装
sudo apt-get install -y software-properties-common # To make add-apt-repository work
sudo add-apt-repository ppa:dennis.guse/sip-tools
sudo apt-get update
sudo apt-get install python-pjsua
sudo apt-get install python-pjsua2
To check if everything went well:
python
import pjsua
https://stackoverflow.com/questions/20195542/python-how-to-get-the-import-pjsua-giving-no-module-named-pjsua
3)Building PJSUA2 and SWIG
The PJSUA2 C++ library will be built by default by PJSIP build system. Standard C++ library is required. If you intend to use Python SWIG module (see below), you need to configure PJSIP with --enable-shared
option, i.e.:
./configure --enable-shared
make dep & make
sudo make install
https://www.pjsip.org/docs/book-latest/html/intro_pjsua2.html#building-python-and-java-swig-modules
装好pjsua2就可以启动pygui测试了拨号了,这个例子带图形界面,ui用的Tkinter,另外一个带gui的例子是vidgui,ui用的qt
6、Using OpenCORE AMR NB and WB Codecs
https://trac.pjsip.org/repos/wiki/Using-OpenCORE-AMR-NB-WB-Codec
#opencore-amr 和 vo-amrwbenc
./configure --prefix=$(pwd)/_install --host=arm-linux-gnueabihf CC=/usr/local/arm/gcc-4.9.4-arm-buildroot-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc
make
make install
装好之后将两个库的_install目录合并,合并到opencore-amr-0.1.3/_install
#pjproject
./configure --prefix=/home/dong/pjproject-2.8/_install --host=arm-linux-gnueabihf CC=/usr/local/arm/gcc-4.9.4-arm-buildroot-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --disable-libwebrtc CFLAGS=-I/home/dong/alsa/include LDFLAGS=-L/home/dong/alsa/lib --with-opencore-amr=$(pwd)/third_party/opencore-amr-0.1.3/_install
make dep
make
make install
ln -s libopencore-amrnb.so.0.0.3 libopencore-amrnb.so.0
ln -s libopencore-amrwb.so.0.0.3 libopencore-amrwb.so.0
ln -s libvo-amrwbenc.so.0.0.4 libvo-amrwbenc.so.0
