Ubuntu 16.04.5下FFmpeg编译与开发环境搭建

PC环境： Ubuntu 18.04 上面只要安装下面的提示安装即可，基本上不必再下载依赖库的源代码进行编译和安装

编译步骤：

1， 安装相关工具：

  1. sudo apt  install -y autoconf automake build-essential git libass-dev libfreetype6-dev libsdl2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev pkg-config texinfo wget zlib1g-dev  
  2. sudo apt  install -y nasm yasm cmake mercurial  

2，git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg,得到文件夹ffmpeg，进入ffmpeg文件夹：

  1. ./configure --enable-shared  --prefix=/usr/local/ffmpeg

安装到/usr/local/ffmpeg下，可通过“--prefix=安装目录”进行修改。--enable-shared：指定生成动态库，默认是静态库。静态库不方便后续开发。

      2.sudo make 

      3.sudo make install  


3，添加ffmpeg库的链接:

在/etc/ld.so.conf中 末尾添加 /usr/local/ffmpeg/lib  即可，执行

  1. sudo ldconfig  

4.安装VS Code

参考https://blog.csdn.net/u011258217/article/details/78693564

---------------------------------------------------  ubuntu 16.04.5 下还需要按照一下提示进行安装依赖  -------------------------------------

Ubuntu下安装和编译ffmpeg
 
1、安装依赖包
sudo apt-get update
sudo apt-get -y --force-yes install autoconf automake build-essential libass-dev libfreetype6-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
2、建立安装包的源文件夹
mkdir ~/ffmpeg_sources
    - ffmpeg_sources – 源文件.
    - ffmpeg_build – 各种lib被安装在此文件夹.
    - bin – 各种bin被安装在此文件夹
 
    我已经把所需要的一下文件都下载整理，存在网盘，需要的可以直接获取链接：http://pan.baidu.com/s/1dD8RYEH 密码：xgoz

sudo  apt  install   yasm  libx264  libx265  libfdk-aac libmp3lame libopus libvpx  -y

sudo  apt  install   yasm  libx264-dev   libx265-dev  libfdk-aac-dev libmp3lame-dev  libopus-dev  libvpx-dev   -y
 
3、Yasm
cd ~/ffmpeg_sources
wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar xzvf yasm-1.3.0.tar.gz
cd yasm-1.3.0
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"
make
make install
make distclean
4、libx264
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="$HOME/bin:$PATH" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static
PATH="$HOME/bin:$PATH" make
make install
make distclean
问题：不知道是不是环境变量的关系，很多标准command不能用，参考另一个笔记：linux下提示bash:command not found 
export PATH=/bin:/sbin:/usr/bin:/usr/sbin

5、libx265

  265的源一直没下载下来，也暂时不用x265，所以没有安装，后续编译ffmpeg不编译x265就可以。

6、libfdk-aac

cd ~/ffmpeg_sources
wget -O fdk-aac.tar.gz https://github.com/mstorsjo/fdk-aac/tarball/master  
git clone https://github.com/mstorsjo/fdk-aac.git

https://github.com/mstorsjo/fdk-aac/archive/master.zip

tar xzvf fdk-aac.tar.gz 
cd mstorsjo-fdk-aac* 
autoreconf -fiv 
./configure --prefix="$HOME/ffmpeg_build" --disable-shared 
make 
make install 
make distclean
7、libmp3lame 
sudo apt-get install nasm
cd ~/ffmpeg_sources
wget http://downloads.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gz
tar xzvf lame-3.99.5.tar.gz
cd lame-3.99.5
./configure --prefix="$HOME/ffmpeg_build" --enable-nasm --disable-shared
make
make install
make distclean
8、libopus 
cd ~/ffmpeg_sources
wget http://downloads.xiph.org/releases/opus/opus-1.1.tar.gz
tar xzvf opus-1.1.tar.gz
cd opus-1.1
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install
make distclean
9、libvpx 
cd ~/ffmpeg_sources
wget http://webm.googlecode.com/files/libvpx-v1.3.0.tar.bz2     ## ！！！！！   这个应该下不下来，可以百度一下替代， 换上最新版本的，不要用这个，有点太低了。
http://ftp.osuosl.org/pub/blfs/conglomeration/libvpx/
wget -c  http://ftp.osuosl.org/pub/blfs/conglomeration/libvpx/libvpx-1.7.0.tar.gz
tar xjvf libvpx-v1.3.0.tar.bz2
cd libvpx-v1.3.0
PATH="$HOME/bin:$PATH" ./configure --prefix="$HOME/ffmpeg_build" --disable-examples --disable-unit-tests
PATH="$HOME/bin:$PATH" make
make install
make clean

                  ##  下面的这个不必了，直接上github上下载源码即可，   https://github.com/FFmpeg/FFmpeg.git
安装编译ffmpeg
cd ~/ffmpeg_sources
wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
tar xjvf ffmpeg-snapshot.tar.bz2
cd ffmpeg
PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure 
  --prefix="$HOME/ffmpeg_build" 
  --pkg-config-flags="--static" 
  --extra-cflags="-I$HOME/ffmpeg_build/include" 
  --extra-ldflags="-L$HOME/ffmpeg_build/lib" 
  --bindir="$HOME/bin" 
  --enable-gpl 
  --enable-libass 
  --enable-libfdk-aac 
  --enable-libfreetype 
  --enable-libmp3lame 
  --enable-libopus 
  --enable-libtheora 
  --enable-libvorbis 
  --enable-libvpx 
  --enable-libx264 
  --enable-libx265 
  --enable-nonfree
PATH="$HOME/bin:$PATH" make
make install
make distclean
hash -r
查看ffmpeg是否安装成功，用ffmpeg -version

之后我们就可以使用ffmpeg 将文件转化成ts文件，以备m3u8-segmenter切片，搭建hls流媒体服务器。

另外有参考源代码：

5.测试环境

#include <stdio.h>
#include <libavformat/avformat.h>
#include <libswscale/swscale.h>
#include <libavfilter/avfilter.h>

#define dbmsgc(fmt, args ...) printf("cong:%s[%d]: "fmt"
", __FUNCTION__, __LINE__,##args)
//#define dbmsg(fmt, args ...) printf("cong:%s:%s[%d]: "fmt"
",__FILE__, __FUNCTION__, __LINE__,##args)
int main(int argc, char **argv)
{
    int i=0;
    AVFormatContext *pFormatCtx = NULL;
    avcodec_register_all();
#if CONFIG_AVDEVICE
    avdevice_register_all();
#endif
   avfilter_register_all();
    av_register_all();

    if(avformat_open_input(&pFormatCtx, argv[1], NULL, NULL)!=0)
        return -1; // Couldn't open file

    if(avformat_find_stream_info(pFormatCtx, NULL)<0)
        return -1; // Couldn't find stream inform
    av_dump_format(pFormatCtx,0, 0, 0);

    return 0;
}

　　

6..编写Makefile

FFMPEG=/usr/local/ffmpeg
CC=gcc
CFLAGS=-g -I$(FFMPEG)/include
LDFLAGS = -L$(FFMPEG)/lib/ -lswscale -lswresample -lavformat -lavdevice -lavcodec -lavutil -lavfilter  -lm 
TARGETS=test
all: $(TARGETS)
test:test.c
    $(CC) $(CFLAGS) -o $@ $^ $(LDFLAGS) -std=c++11 #注意这里的-std=c++11

clean:
    rm -rf $(TARGETS)

　　

7.make

8../test
