videolan x265 源代码下载、编译、测试 【2015-8-11】更新链接
目前有多个实现HEVC/H.265/MPEG-H标准的项目叫做x265，本文主要关注 Videolan旗下的x265
项目主页是：https://www.videolan.org/developers/x265.html
1、配置源代码管理工具 Mercurial
该项目的源代码管理工具是Mercurial
在该公司的下载主页下载对应的系统的版本：http://mercurial.selenic.com/downloads
我的系统是 64位 win7：下载的是http://mercurial.selenic.com/release/windows/mercurial-3.2.1-x64.msi
安装后，在cmd下，运行输入：hg 出现下面的信息表明你的hg 安装成功
Microsoft Windows [版本 6.1.7601] 版权所有 (c) 2009 Microsoft Corporation。保留所有权利。 C:\Users\Administrator>hg 分布式软件配置管理工具 - 水银 基本命令: add add the specified files on the next commit annotate show changeset information by line for each file clone make a copy of an existing repository commit commit the specified files or all outstanding changes diff diff repository (or selected files) export dump the header and diffs for one or more changesets forget forget the specified files on the next commit init create a new repository in the given directory log show revision history of entire repository or files merge merge working directory with another revision pull pull changes from the specified source push push changes to the specified destination remove remove the specified files on the next commit serve start stand-alone webserver status show changed files in the working directory summary summarize working directory state update update working directory (or switch revisions) (use "hg help" for the full list of commands or "hg -v" for details)
2、使用hg 下载源代码
建立源代码目录： G:\HEVC应用\x265-videolan\x265
在该目录下运行命令： hg clone http://hg.videolan.org/x265【更新：2015-8-11】发现这个链接失效
【请用这个链接】 hg clone https://bitbucket.org/multicoreware/x265
然后开始从服务器端下载源代码
G:\HEVC应用\x265-videolan>cd x265 G:\HEVC应用\x265-videolan\x265>hg clone http://hg.videolan.org/x265 目标目录: x265 正在请求全部修改 正在增加修改集 正在增加清单 正在增加文件改变 已增加 8888 个修改集，包含 20901 个改变，修改了 680 个文件 updating to branch default 216 files updated, 0 files merged, 0 files removed, 0 files unresolved G:\HEVC应用\x265-videolan\x265>

6 个目录 10,194,780,160 可用字节
G:\HEVC应用\x265-videolan\x265\x265>3个源代码管理的文件夹： .hg .hgignore .hgtags
3个源代码文件夹：build doc source
其中 source中包含所有的源代码、build包含windows、linux、Mac 3种系统下的编译文件、doc中包含一些参数配置文档（目前不清楚具体的作用）
仔细阅读 build/readme.txt ，里面有详细的编译要求：下面是必须的
= Mandatory Prerequisites =
* GCC, MSVC (9, 10, 11, 12), Xcode or Intel C/C++
* CMake 2.8.8 or later http://www.cmake.org
* On linux, ccmake is helpful, usually a package named cmake-curses-gui
* GCC, MSVC (9, 10, 11, 12), Xcode or Intel C/C++
* CMake 2.8.8 or later http://www.cmake.org
* On linux, ccmake is helpful, usually a package named cmake-curses-gui
Note: MSVC12 requires cmake 2.8.11 or later
我使用的是 MSVC2012 ，需要下载 cmake 2.8.11 之上的版本
下面是cmake windows下的安装包：
http://www.cmake.org/files/v2.8/cmake-2.8.12.2-win32-x86.exe
3、准备编译所需的第三方程序、库
3.1 yasm
x265中有汇编代码，需要汇编器进行编译
For Windows, download
http://www.tortall.net/projects/yasm/releases/yasm-1.2.0-win32.exe or
http://www.tortall.net/projects/yasm/releases/yasm-1.2.0-win64.exe
http://www.tortall.net/projects/yasm/releases/yasm-1.2.0-win32.exe or
http://www.tortall.net/projects/yasm/releases/yasm-1.2.0-win64.exe
下载ysam后，在命令行下输入： PATH
G:\HEVC应用\x265-videolan\x265\x265> PATH PATH=C:\Python27\;C:\Program Files (x86)\Common Files\NetSarang;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\W 6)\Windows Kits\8.0\Windows Performance Toolkit\;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files\TortoiseSVN\bin;C:\Pr返回系统环境变量PATH的值，这个是系统默认的搜索路径，将下载的鸭舌帽拷贝到其中一个目录中，我推荐： c:/windows
将下载的文件改名为 yasm.exe 去掉后面的-1.2.0-win32
然后在命令行中输入： yasm --version
若返回下面的信息，表明按照正确
G:\HEVC应用\x265-videolan\x265\x265>yasm --version yasm 1.2.0 Compiled on Oct 31 2011. Copyright (c) 2001-2011 Peter Johnson and other Yasm developers. Run yasm --license for licensing overview and summary. G:\HEVC应用\x265-videolan\x265\x265>
3.2 安装VisualLeakDetector
下载VisualLeakDetector： https://vld.codeplex.com/releases
下载后安装即可
【可能需要重启】
4、 根据Visual studio 的版本，2012 是MSVC11 ，生成对应的.sln 工程文件
进入\build\vc11-x86 ，双击 make-solutions.bat
生成cmake所需的文件
打开cmake gui程序
选择 源代码所在的目录，点击 configure，在没有任何错误的情况下，点击 genearate，会生成 .sln文件，双击即可，在visual studio 2012 下会打开工程
但是双击 make-solutions.bat， 出现问题：
-- Looking for include file getopt.h - not found CMake Error at C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/CheckIncludeFiles.cmake:76 (file): file Internal CMake error when trying to open file: G:/HEVC应用/x265-videolan/x265/x265/build/vc11-x86/CMakeFiles/CMakeError.log for writing. Call Stack (most recent call first): CMakeLists.txt:347 (check_include_files) -- Configuring incomplete, errors occurred! CMake Error: Cannot open file for write: G:/HEVC应用/x265-videolan/x265/x265/build/vc11-x86/CMakeCache.txt.tmp CMake Error: : System Error: No such file or directory CMake Error: Unable to open cache file for save. G:/HEVC应用/x265-videolan/x265/x265/build/vc11-x86/CMakeCache.txt CMake Error: : System Error: No such file or directory后来，发现是中文路径的原因，所有路径不能含有中文字符
我得路径是 ： G:\HEVC应用\x265-videolan\x265\x265，其中HEVC应用是含有中文，所以出错
</pre>在去掉中文字符后，双击 make-solutions.bat，运行结果：</div><div><pre code_snippet_id="528746" snippet_file_name="blog_20141122_9_9663501" name="code" class="html">-- cmake version 2.8.12.2 -- The C compiler identification is MSVC 17.0.50727.1 -- The CXX compiler identification is MSVC 17.0.50727.1 -- Check for working C compiler using: Visual Studio 11 -- Check for working C compiler using: Visual Studio 11 -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working CXX compiler using: Visual Studio 11 -- Check for working CXX compiler using: Visual Studio 11 -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detected x86 target processor -- Looking for include file stdint.h -- Looking for include file stdint.h - found -- Looking for include file inttypes.h -- Looking for include file inttypes.h - not found -- Found yasm: C:/Windows/yasm.exe (found version "1.2.0") -- Found Yasm 1.2.0 to build assembly primitives -- hg found at C:/Program Files/Mercurial/hg.exe -- x265 version 1.4+113-346fccbba4de -- The ASM_YASM compiler identification is unknown -- Found assembler: C:/Windows/yasm.exe -- Looking for strtok_r -- Looking for strtok_r - not found -- Looking for include file getopt.h -- Looking for include file getopt.h - not found -- Configuring done -- Generating done -- Build files have been written to: G:/x265-videolan/x265/x265/build/vc11-x86
结束后，会自动打开 cmake gui：
先点击 Configure，
在确认没有任何红色的选项后，点击 Generate
在目录下生成 x265.sln
双击打开，在visual studio 2012 下 打开x265 项目，截图：
一共有8个工程
