Linux下 FFmpeg 编译安装
FFmpeg是一套可以用来记录、转换数字音频、视频,并能将其转化为流的开源计算机程序。
一、FFmpeg安装
安装依赖包:
yum install libtheora-devel libvorbis-devel
FFmpeg编译安装:
由于系统不同,会导致依赖也不尽相同,需根据报错信息逐渐安装依赖
wget http://ffmpeg.org/releases/ffmpeg-3.3.2.tar.bz2 tar jxvf ffmpeg-3.3.2.tar.bz2 cd ffmpeg-3.3.2
# 如下是个人需要的编译参数,可以根据实际情况增减
./configure --prefix=/usr/local/ffmpeg \
--enable-shared \ --enable-libfdk-aac \ --enable-gpl \ --enable-nonfree \ --enable-postproc \ --enable-avfilter \ --enable-pthreads \ --enable-libmp3lame \ --enable-libtheora \ --enable-libvorbis \ --enable-libx264 \ --enable-libxvid \ --enable-decoder=libx264 \ --enable-encoder=libx264
make && make install
安装后,查看版本
./bin/ffmpeg -version
转码:
ffmpeg -i input.mp4 output.avi
二、FFmpeg安装错误解决
有的包下载缓慢,备用下载地址: http://pan.baidu.com/s/1hsEeSNM
- 报错:
yasm/nasm not found or too old. Use --disable-yasm for a crippled build
# rpm包存在的话,可以直接yum安装 yasm,没有则编译安装
wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz tar -zxvf yasm.tar.gz ./configure make make install
- 报错:
ERROR: libfdk_aac not found
https://sourceforge.net/projects/opencore-amr/files/fdk-aac/
下载fdk-aac-0.1.5.tar.gz
./configure&& make && make install
- 报错:
ERROR: libtheora not found
http://downloads.xiph.org/releases/theora/?C=M;O=D libtheora-1.2.0alpha1.tar.gz ./configure && make && make install
- 如下报错:
*** Could not run Ogg test program, checking why... *** The test program failed to compile or link. See the file config.log for the *** exact error that occured. This usually means Ogg was incorrectly installed *** or that you have moved Ogg since it was installed.
http://downloads.xiph.org/releases/ogg/?C=M;O=D libogg-1.3.2.tar.gz ./configure && make && make install
- 报错:
ERROR: libvorbis not found
http://downloads.xiph.org/releases/vorbis/ libvorbis-1.3.3.tar.gz
- 报错:
ERROR: libmp3lame >= 3.98.3 not found
http://downloads.sourceforge.net/lame
https://sourceforge.net/projects/lame/files/lame/3.99/,
我下到的是lame-3.99.5.tar.gz
./configure && make && make install
- 报错:
ERROR: libx264 not found
git clone git://git.videolan.org/x264.git ./configure --enable-shared && make && make install
- 报错:
ERROR: libxvid not found
http://downloads.xvid.org/downloads/xvidcore-1.3.2.tar.gz cd build/generic/ ./configure && make && make install
- 库文件找不到时解决:
ldd /data/server/ffmpeg/bin/ffmpeg # 查看依赖库文件,找到no found的库文件 find / -name libavdevice.so # 查找库文件位置 vim/etc/ld.so.conf # 如存在,添加库文件位置 /data/server/ffmpeg/lib/ ldconfig # 重新加载,使新库文件生效
3.动态链接库
$ sudo vi /etc/ld.so.conf include ld.so.conf.d/*.conf /usr/local/ffmpeg/lib ///usr/local/ffmpeg 目录是我ffmpeg安装目录,根据你的安装目录改吧 $ sudo ldconfig
4.为 Ffmpeg 加入环境变量
vi /etc/profile
加入以下内容:
export PATH="/usr/local/ffmpeg/bin:$PATH"
然后保存并运行source /etc/profile
