windows7下ffmpeg编译支持x265

一. 下载ffmpeg

之前的2.1.1版本的ffmpeg不支持x265,在http://www.ffmpeg.org/releases/下载2.3版本ffmpeg-2.3.tar.gz，解压到D:\MinGW\msys\1.0\home\Administrator\source，解压出ffmpeg-2.3文件夹。

二. mingw编译 x265

准备工作，利用tortoiseHg的Locate下载好x265文件，位于D:\MinGW\msys\1.0\home\Administrator\source\x265。

下载x265源代码

通过Tortoisehg下载x265, x265的下载地址为https://bitbucket.org/multicoreware/x265/src

TortoiseHg安装完成后，新建x265文件夹(如D:\x265)，在D:\x265鼠标右键菜单TortoiseHg->clone

安装在D:\MinGW\msys\1.0\home\Administrator\source\x265

1. 双击msys.bat打开mingw32

cd /d/MinGW/msys/1.0/home/Administrator/source/x265/build/msys

执行make-Makefiles.sh

出现CMake

配置好vld,yasm.exe,support_winxp, 输出路径(即make install安装路径), Configure, Generate, File->exit.

mingw环境下: make

等待完成100%,

然后执行make install

x265输出路径(C:\ProgramFiles (x86)\x265)下 include && lib && bin 拷贝到D:\MinGW\msys\1.0\home\Administrator\install\对应的include&& lib && bin下面.

三. 编译ffmpeg

mingw32 下面进入/d/MinGW/msys/1.0/home/Administrator/source/ffmpeg-2.3

执行configure(增加libx265)

./configure   --prefix=/home/Administrator/install--extra-cflags=-I/home/Administrator/install/include  --extra-ldflags=-L/home/Administrator/install/lib --enable-gpl   --enable-version3   --enable-memalign-hack --enable-nonfree--disable-static --enable-shared --disable-doc --disable-htmlpages--disable-manpages --disable-podpages --disable-txtpages --enable-bzlib--enable-zlib --enable-iconv --enable-libx264 --enable-libx265 --enable-libxavs--enable-libmp3lame --enable-libfaac --enable-libfdk-aac --enable-libvo-aacenc--enable-libvo-amrwbenc --enable-libopencore-amrnb --enable-libopencore-amrwb

配置结束

执行make

编译出错:

以libavutil/file.c为例

对策：#include<unistd.h> 或 #include <zlib.h> 或 #include"swf.h" 前面添加#include<windows.h>

 

make install

提示avcodec-55.dll 文件已存在，应该是误报，再执行一遍make install

最终执行完毕

测试：将h264文件app.h264 转码为h265文件app.hevc

ffmpeg.exe -i /d/app.h264 -vcodec libx265 /d/app.hevc
