在ubuntu 14.04中安装ffmpeg的问题
我尝试根据https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu在unbutu中安装ffmpeg我使用下面的代码创建一个shell文件
sudo apt-get update sudo apt-get -y install autoconf automake build-essential libass-dev libfreetype6-dev libgpac-dev \ libsdl1.2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libx11-dev \ libxext-dev libxfixes-dev pkg-config texi2html zlib1g-dev mkdir ~/ffmpeg_sources cd ~/ffmpeg_sources wget http://download.videolan.org/pub/x264/snapshots/last_x264.tar.bz2 tar xjvf last_x264.tar.bz2 cd x264-snapshot* PATH="$PATH:$HOME/bin" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static --disable-opencl PATH="$PATH:$HOME/bin" make make install make distclean sudo apt-get install unzip cd ~/ffmpeg_sources wget -O fdk-aac.zip https://github.com/mstorsjo/fdk-aac/zipball/master unzip fdk-aac.zip cd mstorsjo-fdk-aac* autoreconf -fiv ./configure --prefix="$HOME/ffmpeg_build" --disable-shared make make install make distclean cd ~/ffmpeg_sources wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2 tar xjvf ffmpeg-snapshot.tar.bz2 cd ffmpeg PATH="$PATH:$HOME/bin" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \ --prefix="$HOME/ffmpeg_build" \ --extra-cflags="-I$HOME/ffmpeg_build/include" \ --extra-ldflags="-L$HOME/ffmpeg_build/lib" \ --bindir="$HOME/bin" \ --enable-libfdk-aac \ --enable-libx264 \ PATH="$PATH:$HOME/bin" make make install make distclean hash -r （我对此文件添加执行权限）并在命令行运行./mybashfile.sh）
它运行正常并开始下载，但终端输出的最后一行是

问题出在哪儿？ 以及如何正确安装ffmpeg？
最简单的方法是下载从FFmpeg下载页面链接的静态构建之一 。
然后你可以运行它
$ /opt/ffmpeg-2.3.3-64bit-static/ffmpeg
（或将存档扩展到的任何地方）。
这是一个安装示例脚本（下载/提取/放入用户bin PATH目录） 最新的 ffmpeg静态版本：
wget https://johnvansickle.com/ffmpeg/releases/ffmpeg-release-64bit-static.tar.xz tar -xvJf ffmpeg-release-64bit-static.tar.xz --strip-components=1 -C ./usr/bin
