videolan x265 源代码下载、编译、测试【二】 【2015-8-11更新 修改Release版本】

在上一篇博客中 已经完成源代码下、编译环境配置、MSVC工程文件生成、VS2012打开工程

本博客就是运行、测试

1、VS2012 编译、生成 x265 的静态库、动态库、可执行程序

在vs2012 下，生成全部工程，当前选择是debug模式，会在build\vc11-x86\Debug目录下生成 libx265.lib 、 libx265.dll 、x265.exe

运行命令：x265 -V 

返回版本号、使用的汇编指令集

x265 [info]: build info [Windows][MSVC 1700][32 bit] 8bpp

2、测试

运行命令： x265 --help >help.txt

得到x265 的help文件，仔细阅读

输入：

x265支持 YUV 、 Y4M 两种输入

Syntax: x265 [options] infile [-o] outfile
    infile can be YUV or Y4M

输出：

x265 支持H.265 裸码流输出
    outfile is raw HEVC bitstream

3、生成Release版本

直接生成Release会出错，需要修改：x265-static.vcxproj工程文件

错误的原因是 使用汇编器YASM对.asm源代码文件进行汇编后生成的obj文件名 与 链接时使用的文件名不对应：pixel-a.asm文件生成的文件名不是 pixel-a.asm.obj，而是pixel-a.obj

这个错误折腾我好久，终于在阅读编译文件是发现：x265-static.vcxproj工程文件中调用yasm生成obj的命令行 ，指明输出的是pixel-32.asm.obj

"C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin\yasm.exe" -f win32 -DPREFIX -DARCH_X86_64=0 -DHAVE_ALIGNED_STACK=0 -DHIGH_BIT_DEPTH=0 -DBIT_DEPTH=8 -DX265_NS=x265 G:/x265-videolan/2015-811/x265/source/common/x86/pixel-32.asm -o pixel-32.asm.obj

但是实际上：输出的是pixel-32.obj，所以在生成库的时候 一直说找不到pixel-32.asm.obj。。。。。。 我就是醉了  

    <Object Include="pixel-a.asm.obj" />    <Object Include="const-a.asm.obj" />    <Object Include="cpu-a.asm.obj" />    <Object Include="ssd-a.asm.obj" />    <Object Include="mc-a.asm.obj" />    <Object Include="mc-a2.asm.obj" />    <Object Include="pixel-util8.asm.obj" />    <Object Include="blockcopy8.asm.obj" />    <Object Include="pixeladd8.asm.obj" />    <Object Include="dct8.asm.obj" />    <Object Include="sad-a.asm.obj" />    <Object Include="intrapred8.asm.obj" />    <Object Include="ipfilter8.asm.obj" />    <Object Include="loopfilter.asm.obj" />    <Object Include="pixel-32.asm.obj" />

我就只只好暴力的 修改：让obj文件强制 指向完整的obj路径，然后就ok
