libx264

H.264 video encoder. See the H.264 Encoding Guide for more information and usage examples.

Requires ffmpeg to be configured with --enable-gpl --enable-libx264.

If your repository provides libx264-dev version ≥ 118 then you can install that instead of compiling:

sudo apt-get install libx264-dev

Otherwise you can compile:

 Compile FFmpeg for Ubuntu, Debian, or Mint

https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

순서대로 설치 합니다.

Get the Dependencies

These are packages required for compiling, but you can remove them when you are done if you prefer:

sudo apt-get update -qq && sudo apt-get -y install \
  autoconf \
  automake \
  build-essential \
  cmake \
  git-core \
  libass-dev \
  libfreetype6-dev \
  libsdl2-dev \
  libtool \
  libva-dev \
  libvdpau-dev \
  libvorbis-dev \
  libxcb1-dev \
  libxcb-shm0-dev \
  libxcb-xfixes0-dev \
  pkg-config \
  texinfo \
  wget \
  zlib1g-dev

In your home directory make a new directory to put all of the source code and binaries into:

mkdir -p ~/ffmpeg_sources ~/bin

Compilation & Installation

This guide assumes that you want to install some of the most common third-party libraries. Each section provides you with the commands needed to install that library.

For each section, copy-paste the entire code-block into your shell.

If you do not require certain features, you may skip the relevant section (if it is not required) and then remove the appropriate ./configure option in FFmpeg. For example, if libvpx is not needed, skip that section and then remove --enable-libvpx from the Install FFmpegsection.

NASM

An assembler used by some libraries.

cd ~/ffmpeg_sources && \
wget https://www.nasm.us/pub/nasm/releasebuilds/2.13.03/nasm-2.13.03.tar.bz2 && \
tar xjvf nasm-2.13.03.tar.bz2 && \
cd nasm-2.13.03 && \
./autogen.sh && \
PATH="$HOME/bin:$PATH" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" && \
make && \
make install

Yasm

An assembler used by some libraries.

If your repository provides yasm version ≥ 1.2.0 then you can install that instead of compiling:

sudo apt-get install yasm

Otherwise you can compile:

cd ~/ffmpeg_sources && \
wget -O yasm-1.3.0.tar.gz https://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz && \
tar xzvf yasm-1.3.0.tar.gz && \
