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:
- 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
- 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:
- ./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
- 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 -------------------------------------
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
sudo apt install yasm libx264-dev libx265-dev libfdk-aac-dev libmp3lame-dev libopus-dev libvpx-dev -y
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"\n", __FUNCTION__, __LINE__,##args)
//#define dbmsg(fmt, args ...) printf("cong:%s:%s[%d]: "fmt"\n",__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

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
