#!/bin/bash

# Bash script to install latest version of ffmpeg and its dependencies on Ubuntu 12.04 or 14.04
# Inspired from https://gist.github.com/faleev/3435377

# Remove any existing packages:
sudo apt-get -y remove ffmpeg x264 libav-tools libvpx-dev libx264-dev

# Get the dependencies (Ubuntu Server or headless users):
sudo apt-get update
sudo apt-get -y install build-essential checkinstall git libfaac-dev libgpac-dev \
  libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev librtmp-dev libtheora-dev \
    libvorbis-dev pkg-config texi2html yasm zlib1g-dev

# Install x264
sudo apt-get -y install libx264-dev
cd
git clone --depth 1 git://git.videolan.org/x264
cd x264
./configure --enable-static
make
sudo checkinstall --pkgname=x264 --pkgversion="3:$(./version.sh | \
  awk -F'[" ]' '/POINT/{print $4"+git"$5}')" --backup=no --deldoc=yes \
    --fstrans=no --default

# Install AAC audio decoder
cd
wget http://downloads.sourceforge.net/opencore-amr/fdk-aac-0.1.0.tar.gz
tar xzvf fdk-aac-0.1.0.tar.gz
cd fdk-aac-0.1.0
./configure
make
sudo checkinstall --pkgname=fdk-aac --pkgversion="0.1.0" --backup=no \
  --deldoc=yes --fstrans=no --default

# Install VP8 video encoder and decoder.
cd
git clone --depth 1 https://chromium.googlesource.com/webm/libvpx 
cd libvpx
./configure
make
sudo checkinstall --pkgname=libvpx --pkgversion="1:$(date +%Y%m%d%H%M)-git" --backup=no \
  --deldoc=yes --fstrans=no --default

# Add lavf support to x264
# This allows x264 to accept just about any input that FFmpeg can handle and is useful if you want to use x264 directly. See a more detailed explanation of what this means.
cd ~/x264
make distclean
./configure --enable-static
make
sudo checkinstall --pkgname=x264 --pkgversion="3:$(./version.sh | \
  awk -F'[" ]' '/POINT/{print $4"+git"$5}')" --backup=no --deldoc=yes \

#downloaded rtmpdump
http://rtmpdump.mplayerhq.hu/
git clone git://git.ffmpeg.org/rtmpdump
cd rtmpdump
為了得到調(diào)試信息,這里簡(jiǎn)單修改一下文件夾rtmpdump和librtmp的Makefile文件,添加-g參數(shù),注意去掉優(yōu)化參數(shù)-O2那項(xiàng)

在rtmpdump的Makefile中的

OPT=-O2

CFLAGS=-Wall -g $(XCFLAGS) $(INC) $(DEF) $(OPT)

在librtmp的Makefile中的

CFLAGS=-Wall ....  -g
2.安裝相關(guān)依賴類
需要用到的依賴庫(kù)是zlib, openssl庫(kù),使用如下命令安裝
sudo apt-get install openssl 
sudo apt-get install libssl-dev
sudo apt-get install zlib1g-dev
可以先查看可用的安裝包
sudo apt-cache search openssl

通過(guò)閱讀Makefile文件,我發(fā)現(xiàn)rtmpdump需要引用的動(dòng)態(tài)庫(kù)如下

-lz -lssl -lcrypto -lrtmp -lpthread

make后會(huì)生成4個(gè)可執(zhí)行文件, 分別是rtmpdump,rtmpsvr, rtmpsuck, rtmpgw, 其中pthread直會(huì)在rtmpsvr, rtmpsuck, rtmpgw這3個(gè)程序中用到.

3.編譯安裝
make
sudo make install
首先要保證相關(guān)庫(kù)已經(jīng)成功安裝到/usr/local/lib下面
再要保證/usr/local/lib在/etc/ld.so.conf配置文件中,然后

sudo ldconfig
來(lái)更新動(dòng)態(tài)庫(kù)緩存
檢查rtmpdump所有依賴庫(kù)是否都引用成功
ldd rtmpdump
#downloaded libogg
wget https://downloads.xiph.org/releases/ogg/libogg-1.3.2.tar.xz
Installation of libogg

Install libogg by running the following commands:

./configure --prefix=/usr    \
            --disable-static \
            --docdir=/usr/share/doc/libogg-1.3.2 &&
make
To test the results, issue: make check.

Now, as the root user:

make install
#downloaded libvorbis-1.3.5
wget https://downloads.xiph.org/releases/vorbis/libvorbis-1.3.5.tar.xz
Installation of libvorbis

Optionally fix installation of the package when --enable-docs is added to the configure switches:

sed -i '/components.png \\/{n;d}' doc/Makefile.in
Install libvorbis by running the following commands:

./configure --prefix=/usr --disable-static &&
make
To test the results, issue: make LIBS=-lm check.

Now, as the root user:

make install &&
install -v -m644 doc/Vorbis* /usr/share/doc/libvorbis-1.3.5

#downloaded libtheora

wget https://downloads.xiph.org/releases/theora/libtheora-1.1.1.tar.xz
Installation of libtheora

Install libtheora by running the following commands:

sed -i 's/png_\(sizeof\)/\1/g' examples/png2theora.c &&
./configure --prefix=/usr --disable-static &&
make
If you wish to run the tests, issue: make check.

Now, as the root user:

make install

# Installing FFmpeg

# Optional: install qt-faststart
# This is a useful tool if you're showing your H.264 in MP4 videos on the web. It relocates some data in the video to allow playback to begin before the file is completely downloaded. Usage: qt-faststart input.mp4 output.mp4.
cd ~/ffmpeg

我用一段轉(zhuǎn)碼測(cè)試了一下

#ffmpeg -i file.avi output.flv  

發(fā)現(xiàn)報(bào)了一個(gè)庫(kù)找不到的錯(cuò)

去搜索了一下相關(guān)問(wèn)題

于是乎我就

軟鏈接了一下，再次測(cè)試就通過(guò)了
