ubuntu14.04安装ffmpeg的问题

我尝试按照https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu 我使用以下代码创建一个 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

（我为该文件添加了执行权限）并在命令行运行./mybashfile.sh）

它运行正确并开始下载，但最后一行终端输出是

问题在哪里？以及如何正确安装 ffmpeg？

答案1

最简单的方法是下载其中一个静态版本链接自FFmpeg 下载页面。

然后你可以用

$ /opt/ffmpeg-2.3.3-64bit-static/ffmpeg

（或者您将档案扩展到的任何地方）。

答案2

以下是安装的示例脚本（下载/提取/放入用户binPATH 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
