openHEVC 编译 for VS2017+Win10 x64

编译暂未成功，有空再次更新

前期准备：

CMake 3.8

下载: https://cmake.org/download/

1 http://ffmpeg.zeranoe.com/builds/win64/static/ffmpeg-20170503-a75ef15-win64-static.zip  （已编译的程序）

pthreads-w32-2-9 openHEVC 中用到了线程,因此要下载：

1 ftp://sourceware.org/pub/pthreads-win32/pthreads-w32-2-9-1-release.zip

环境配置

1、解压源码

解压后目录及文件夹结构：

 1 "D:\dev\Endvlib\cmake-3.8.1-win64-x64"                         【已解压的目录】 以下类同
 2 "D:\dev\Endvlib\ffmpeg-3.3.1"
 3 "D:\dev\Endvlib\ffmpeg-20170503-a75ef15-win64-static"
 4 "D:\dev\Endvlib\openHEVC-hevc_rext"
 5 "D:\dev\Endvlib\pthreads-w32-2-9-1-release"
 6 "D:\dev\Endvlib\SDL2-2.0.5-win32-x64"
 7 "D:\dev\Endvlib\vsyasm-1.3.0-win64"
 8 "D:\dev\Endvlib\cmake-3.8.1-win64-x64.zip"                        【已下载的文件】 以下类同
 9 "D:\dev\Endvlib\ffmpeg-3.3.1.tar.bz2"
10 "D:\dev\Endvlib\ffmpeg-20170503-a75ef15-win64-static.zip"
11 "D:\dev\Endvlib\openHEVC-hevc_rext.zip"
12 "D:\dev\Endvlib\pthreads-w32-2-9-1-release.zip"
13 "D:\dev\Endvlib\SDL2-2.0.5-win32-x64.zip"
14 "D:\dev\Endvlib\vsyasm-1.3.0-win64.zip"
15 "D:\dev\Endvlib\yasm-1.3.0-win64.exe"

2、取出 pthreadVC2.lib pthreadVC2.dll 这两个文件放到 build 下，（build在openHEVC文件里新建一个）

1 "D:\dev\Endvlib\pthreads-w32-2-9-1-release\Pre-built.2\dll\x64\pthreadGC2.dll"
2 "D:\dev\Endvlib\pthreads-w32-2-9-1-release\Pre-built.2\dll\x64\pthreadVC2.dll"

复制上述两个文件到：

1 "D:\dev\Endvlib\openHEVC-hevc_rext\build\pthreadGC2.dll"
2 "D:\dev\Endvlib\openHEVC-hevc_rext\build\pthreadVC2.dll"

从FFmpeg源码中拷贝以下几个文件到openHEVC同名字的文件夹下（提示缺XXX函数在XXX中，引用无法找到：原因是缺以下几个文件：）

libavutil/fifo.c

libavcodec/frame_thread_encoder.c

1 "D:\dev\Endvlib\ffmpeg-3.3.1\libavutil\fifo.c"
2 "D:\dev\Endvlib\ffmpeg-3.3.1\libavcodec\frame_thread_encoder.c"

复制上述两个文件到：

1 "D:\dev\Endvlib\openHEVC-hevc_rext\libavutil\fifo.c"
2 "D:\dev\Endvlib\openHEVC-hevc_rext\libavcodec\frame_thread_encoder.c"

这两个文件可以放到C:\Windows下

打开CMakeLists.txt（"D:\dev\Endvlib\openHEVC-hevc_rext\CMakeLists.txt"）找到

 1 #find_package(CRYPTOPP_FOUND)
 2 find_package(SDL)
 3 find_package(SDL2)
 4 
 5 set(libfilenames
 6     libavutil/avstring.c
 7     libavutil/atomic.c
 8     libavutil/base64.c
 9     libavutil/bprint.c
10     libavutil/buffer.c
11     libavutil/channel_layout.c
12     .............

在set命令中添加以下几条命令：set() 在Cmake中的意思是将libavutil/avstring.c libavutil/atomic.c 等赋值给变量libfilenames；

 1 #find_package(CRYPTOPP_FOUND)
 2 find_package(SDL)
 3 find_package(SDL2)
 4 
 5 set(libfilenames
 6     libavutil/avstring.c
 7     libavutil/atomic.c
 8     libavutil/base64.c
 9     libavutil/bprint.c
10     libavutil/buffer.c
11     libavutil/channel_layout.c
12      libavutil/fifo.c
13      libavcodec/frame_thread_encoder.c

然后在CMakeLists.txt中找到target_link_libraries(LibOpenHevcWrapper m) 这条语句，这条语句的作用是添加m.lib到LibOpenHevcWrapper这一项目的链接器中。然而m.lib是没有的，找不到，既不是编译阶段能产生的，网上也无法找到，谁知道！因此注释掉：Cmake中 “#”是注释命令！

1 if(CRYPTOPP_FOUND)
2 target_link_libraries(LibOpenHevcWrapper cryptopp)
3 else()
4 # target_link_libraries(LibOpenHevcWrapper m)
5 endif()

你会发现，上述的配置都是按64位的环境来配置的，包括库

准备工作弄完了，可以开始编译了：

1、在openHEVC文件夹里新建一个文件夹：习惯命名build （上面已经完成）

2、为了在别的电脑上（没安装SDL2.X）方便用,将准备过程中下载的SDL包解压后，放到openHEVC文件夹里（可选，此步不执行）

3、将下载的

"D:\dev\Endvlib\yasm-1.3.0-win64.exe"

改名为 yasm.exe 放在openHEVC文件夹里（或系统目录里，例如C:\windows 其实放哪里都行，因为看图，你第一次运行 configure 后，出来的红色区域，路径都是可以改的）

我是直接复制进去重命名为 yasm.exe

4、（可选，此次不执行）将pthreadVC2.lib pthreadVC2.dll这两个文件放到build文件夹下（目的是为了等项目的解决方案即xxx.sln生成后，在链接器中加入pthreadVC2.lib）。也可以放在openHEVC文件夹里，通过在CMakeLists.txt加入以下红色语句：

add_library (LibOpenHevcWrapper ${libfilenames} ${YASM_OBJECTS}) //可以通过这条语句在CMakeLists.txt中定位要加的位置

#target_link_libraries(LibOpenHevcWrapper m)
set(pthreadPATH ../pthreadVC2)
target_link_libraries(LibOpenHevcWrapper ${LINK_LIBRARIES_LIST} ${pthreadPATH})

5、打开Cmake

即运行 "D:\dev\Endvlib\cmake-3.8.1-win64-x64\bin\cmake-gui.exe"

如图：

路径是你自己的路径，路径配好后，点击configure，出现红色背景区域，这红色背景区域的地址都可以改的，特别的是将黄色方框标记的路径改成openHEVC里面的路径：不懂看图

第一次configure:

Finish

 1 DEBUG: CMAKE_SYSTEM_PROCESSOR = AMD64
 2 DEBUG: CMAKE_SYSTEM_NAME      = Windows
 3 DEBUG: SIZEOF_VOID_P      = 4
 4 Detected CPU: haswell
 5 Found components for YASM
 6 YASM_ROOT_DIR  = C:/Program Files (x86)/openHEVC
 7 YASM_INCLUDES  = YASM_INCLUDES-NOTFOUND
 8 YASM_LIBRARIES = YASM_LIBRARIES-NOTFOUND
 9 Could NOT find SDL (missing:  SDL_LIBRARY) 
10 Could NOT find SDL2 (missing:  SDL2_LIBRARY) 
11 Configuring done

修改红色部份为：

1  SDL_LIBRARY  D:/dev/Endvlib/SDL2-devel-2.0.5-mingw/SDL2-2.0.5/x86_64-w64-mingw32/lib/libSDL2.a
2  SDL2_LIBRARY D:/dev/Endvlib/SDL2-devel-2.0.5-mingw/SDL2-2.0.5/x86_64-w64-mingw32/lib/libSDL2.a
3  SDL2_INCLUDE_DIR D:\dev\Endvlib\SDL2-devel-2.0.5-mingw\SDL2-2.0.5\x86_64-w64-mingw32\include 
4  SDLMAIN_LIBRARY D:/dev/Endvlib/SDL2-devel-2.0.5-mingw/SDL2-2.0.5/x86_64-w64-mingw32/lib/libSDL2.a
5  YASM_EXECUTABLE D:/dev/Endvlib/vsyasm-1.3.0-win64/yasm-1.3.0-win64.exe
6

第二次configure:

搞了半天还有错误，不过项目是生成了

6. 点击Cmake的generate按钮，vs项目就生成了！

7、打开build文件夹，将里面没用的工程删掉，不然心烦，如下面左图，删掉后打开vs工程后缀名为.sln的就是解决方案的简称，没错打开的就是这个！发现如图右所示，按图右，在无法加载的工程上右击鼠标，选择移除。

右击LibOpenHevcWrapper项目，选择生成，会发现出现以下错误：

解决办法：在libavcodec/avcodec.h 里面#include "version.h" 后面，其实随便。添加：

#define AV_CODEC_CAP_INTRA_ONLY 0x40000000

#define AV_CODEC_FLAG_QSCALE (1 << 1)

#define AV_CODEC_FLAG_PASS1 (1 << 9)

以上三条语句，根据这个错误在FFmpeg的文件夹libavcodec/avcodec.h里面去ctrl+f 查找，复制到openHEVC的libavcodec/avcodec.h里面

在运行，发现还是错误：如图中注释，总共有三处。
