以上编译，注意都要设置prefix
编译doubango
BUILD_LIBS=${HOME}/build_libs export PATH=${BUILD_LIBS}/bin:${PATH} export PKG_CONFIG_PATH=${BUILD_LIBS}/lib/pkgconfig:${PKG_CONFIG_PATH} ./autogen.sh cd bindings ./autogen.sh cd .. # 关键一步，必须！ autoreconf -fiv ./configure \ CFLAGS=-I${BUILD_LIBS}/include \ LDFLAGS=-I${BUILD_LIBS}/lib \ --with-ssl --with-srtp --with-vpx --with-yuv --with-amr --with-speex --with-speexdsp --enable-speexresampler --enable-speexdenoiser --with-opus --with-gsm --with-ilbc --with-g729 --with-ffmpeg # --with-speexdsp --with-ffmpeg --with-opus # --prefix=${BUILD_LIBS} make sudo make install # for telepresence cp bindings/_common/* ../telepresence/tinywrap

实际编译中，最大的问题就是ffmpeg接口太老。要么改成新接口，要么使用老的ffmpeg（具体哪个版本吾亦没试）
