a）下载：
b）解压
xz -d gstreamer-1.16.
tar -xvf gstreamer-1.16.0.tar
再依次解压
gst-plugins-base-1.16.
gst-plugins-bad-1.16.
gst-plugins-good-1.16.
gst-plugins-ugly-1.16.
gst-libav-1.16.
c）编译
sudo apt-get install build-essential dpkg-dev flex bison autotools-dev automake liborc-dev autopoint libtool gtk-doc-tools libgstreamer1.0-dev
cd gstreamer-1.16.0
./configure
若提⽰错误：
解决：sudo apt-get install bison
再次执⾏./configure，若提⽰错误：
解决：sudo apt-get install flex
./configure
sudo make
sudo make install

sudo vim ~/.bashrc
添加PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH
source ~/.bashrc
cd ..
cd gst-plugins-base-1.16.0
sudo apt-get install libxv-dev libasound2-dev libtheora-dev libogg-dev libvorbis-dev
./configure
sudo make
sudo make install
