Compiling FFmpeg in Linux supports x264 and x265

Compiling FFmpeg in Linux supports x264 and x265

1. Preface

Ffmpeg, x264, x265

2. environment dependency

2.1 Delete the ffmpeg library installed in the system.
Sudo apt-get -- purge remove ffmpeg mplayer x264 x265

2.2 install dependency Libraries
Sudo apt-get update
Sudo apt-get-y -- force-yes install autoconf automake build-essential libass-dev libfreetype6-dev libgpac-dev \
Libsdl1.2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev \
Libxcb-xfixes0-dev pkg-config texi2html zlib1g-dev

Note: The server version can be ignored.
Libsdl1.2-dev libva-dev libvdpau-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev

2.3 download source code

(1) ffmpeg
Git clone git: // source.ffmpeg.org/ffmpeg.git ffmpeg

(2) x264 <pre name = "code" class = "plain"> <pre name = "code" class = "plain"> git clone git: // git.videolan.org/x264.git

(3) x265hg clone https://bitbucket.org/multicoreware/x265

(4) yasm
Yasm is an assembly optimizer on the x86 platform. It can accelerate compilation of ffmpeg x264.
Wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
Tar xzvf yasm-1.3.0.tar.gz

3. Compile

3.1 configure the compilation Output Folder
Export FFMPEG_PATH = "YOUR_PATH"
Export PATH = "$ FFMPEG_PATH/bin: $ PATH"
For example, the output folder is $ HOME/ffmpeg_2.6.3/build_out.
So:
Export FFMPEG_PATH = "$ HOME/ffmpeg_2.6.3/build_out"

3.1 yasm
Cd yasm-1.3.0
./Configure -- prefix = "$ HOME /"
Make
Make install

Or install an existing library (yasm version ≥ 1.3.0)
Sudo apt-get install yasm

3.2x264

Add -- enable-gpl and -- enable-libx264 When configuring ffmpeg config
Cd x264 *
./Configure -- prefix = "$ FFMPEG_PATH" -- enable-shared -- enable-static
Make-j4
Make install
Make clean
Or install the existing library (yasm version ≥ 1.3.0) sudo apt-get install libx264-dev

3.3x265
Cd x265/build/linux
Cmake-G "Unix Makefiles"-DCMAKE_INSTALL_PREFIX = "$ FFMPEG_PATH"-DENABLE_SHARED: bool = off.../source
Make-j4
Make install
Make clean
</Tt> </span>

3.4 aac

Add -- enable-libfdk_aac When configuring ffmpeg config (assuming that -- enable-gpl is enabled at the same time -- enable-nonfree)
PKG_CONFIG_PATH = "$ FFMPEG_PATH/lib/pkgconfig"./configure \
-- Prefix = "$ FFMPEG_PATH "\
-- Pkg-config-flags = "-- static "\
-- Extra-cflags = "-I $ FFMPEG_PATH/include "\
-- Extra-ldflags = "-L $ FFMPEG_PATH/lib "\
-- Enable-gpl \
-- Enable-libass \
-- Enable-libfaac \
-- Enable-libfreetype \
Enable-libmp3lame \
-- Enable-libtheora \
-- Enable-libvorbis \
Enable-libx264 \
Enable-libx265 \
-- Enable-nonfree \
-- Enable-shared \
-- Enable-postproc \
Enable-x11grab \
-- Enable-bzlib \
-- Enable-libxvid \
-- Enable-zlib \
-- Disable-debug

4. Add ffmpeg to the Environment Variable

4.1 Add ffmpeg to Environment Variables
Vim ~ /. Bashrc
Add at last

Export FFMPEG_PATH = "/home/guohe/workspace/ffmpeg_2.6.3/build_out"
Export PATH = "$ FFMPEG_PATH/bin: $ PATH"

4.2 join the Linked database

When ffmpeg is called after compilation, error while loading shared libraries: xxx may occur.

There are two ways to solve this problem:

(1) Change/etc/ld. so. conf
Vim/etc/ld. so. conf

Add $ FFMPEG_PATH/lib at the end

Then run
Sudo ldconfig

(2) Change LD_LIBRARY_PATH

Vim ~ /. Bashrc
Add export LD_LIBRARY_PATH = $ LD_LIBRARY_PATH: $ FFMPEG_PATH/ib
