linux安装ffmpeg
1、下载解压
wget http://www.ffmpeg.org/releases/ffmpeg-3.1.tar.gz
tar -zxvf ffmpeg-3.1.tar.gz
2、 进入解压后目录,输入如下命令/usr/local/ffmpeg为自己指定的安装目录
cd ffmpeg-3.1
./configure --prefix=/usr/local/ffmpeg
make && sudo make install
3、配置变量
vi /etc/profile
在最后PATH添加环境变量:
export PATH=$PATH:/usr/local/ffmpeg/bin
保存退出
查看是否生效
source /etc/profile 设置生效
4、查看版本
ffmpeg -version 查看版本
FFmpeg编译
- 下载代码:git clone https://git.ffmpeg.org/ffmpeg.git
- 然后输入命令进行编译:找到下载的目录下,然后用命令进入这个文件夹下cd ffmpeg,然后输入./configure。
- 竟然没有编译过出现错误是
-
nasm/yasm not found or too old. Use --disable-x86asm for a crippled build.
-
-
If you think configure made a mistake, make sure you are using the latest
-
version from Git. If the latest version fails, report the problem to the
-
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
-
Include the log file "ffbuild/config.log" produced by configure as this will help
-
solve the problem.
分析:yasm是汇编编译器,ffmpeg为了提高效率使用了汇编指令,如MMX和SSE等。所以系统中未安装yasm时,就会报上面错误。
解决错误:安装yasm编译器。安装方法如下:
1)下载:wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar -zxvf yasm-1.3.0.tar.gz
cd yasm-1.3.0
./configure
make && sudo make install(提示:Permission denied,就执行sudo make install)
- 安装成功yasm你可以在进入到ffmpeg的文件夹下,进行./configure
- make
- make install(提示:Permission denied,就执行sudo make install)
- 然后打出ffmpeg

-
Use -h to get full help or, even better, run 'man ffmpeg'
-
这样ffmpeg就安装成功了。
ffplay: command not found
如果你要用到ffplay的时候,发现没有这个命令的时候,是因为ffplay和ffmpeg不是在一起的,需要单独下载。ffplay下载地址 http://evermeet.cx/ffmpeg/ 。把下载下来的文件双击打开运行,如果提示Permission denied,到系统偏好设置,打开安全与隐私,允许ffplay运行就可以了。运行完之后,再在.bash_profile文件配置ffplay path就可以了(这个路径就是ffplay文件的位置)。
./configure --prefix=/usr/local/ffmpeg --enable-gpl --enable-small --arch=x86_64 --enable-nonfree --enable-libfdk-aac --enable-libx264 --enable-filter=delogo --enable-debug --disable-optimizations --enable-shared --enable-libfreetype
##安装libx264
下载地址http://download.videolan.org/pub/videolan/x264/snapshots/
./configure --enable-shared
#make
#make install
libfdk_aac not found
-
fdk_aac 下载地址https://sourceforge.net/projects/opencore-amr/files/fdk-aac/
-
1.解压缩
-
2. ./configure
-
3. make
-
4. make install (sudo make install)
