audio - PJSIP(PJSUA2)-OPUS编解码器

是否可以将PJSIP (PJSUA2)配置为使用OPUS编解码器？

最佳答案

我终于找到了一种方法(ubuntu 14.04，要求PJSIP> = 2.5):

使用以下命令从源代码安装opus@1.1.2:

$ curl -sO http://downloads.xiph.org/releases/opus/opus-1.1.2.tar.gz
$ tar xzvf opus-1.1.2.tar.gz \
  && rm opus-1.1.2.tar.gz \
  && cd opus-1.1.2 \
  && ./configure \
  && make && make check

$ sudo make install \
  && sudo ldconfig

$ ldconfig -p | grep opus
> libopus.so (libc6,x86-64) => /usr/local/lib/libopus.so

根据http://trac.pjsip.org/repos/ticket/1904安装PJSIP@2.5:

curl -sO http://www.pjsip.org/release/2.5/pjproject-2.5.tar.bz2
tar xjf pjproject-2.5.tar.bz2 \
 && rm pjproject-2.5.tar.bz2 \
 && cd pjproject-2.5/ \
 && ./configure --prefix=/usr --enable-shared --with-opus=/usr/local/ \
 && make dep && make

$ sudo make install && sudo ldconfig

确保OPUS可用

std::cout << "Available codecs:\n";
for (auto c : Endpoint::instance()->codecEnum()) {
  std::cout << " - " << c->codecId << " (priority: " << static_cast<int>(c->priority) << ")\n";
}

使用Endpoint::instance()->codecSetPriority("opus/48000", 131);调整优先级
