[ffmpeg]记录一下编译ffmpeg过程中的踩坑

 编译环境win10 64位，目标是编译出32位可以进行视频音频压制操作的ffmpeg。

操作过程和网上大部分博客描述相同，本篇特别将踩坑部分记录下来

 

1.编译lame3.99.5出错，在点击make后出现如下错误

make[3]: *** [xmm_quantize_sub.lo] Error 1
make[3]: Leaving directory '/c/Users/saghul/work/MINGW-packages/mingw-w64-lame/src/build-i686-w64-mingw32/libmp3lame/vector'
Makefile:547: recipe for target 'all-recursive' failed
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory '/c/Users/saghul/work/MINGW-packages/mingw-w64-lame/src/build-i686-w64-mingw32/libmp3lame'
Makefile:349: recipe for target 'all-recursive' failed
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory '/c/Users/saghul/work/MINGW-packages/mingw-w64-lame/src/build-i686-w64-mingw32'
Makefile:276: recipe for target 'all' failed
make: *** [all] Error 2

 解决方法：直接删除 configure 文件中 xmmintrin.h

 

2编译xvid过程，make之后出错

如果make时出现：cc1.exe: error: unrecognized command line option '-mno-cygwin' 错误，请在./configure后make之前修改xvidcore\build\generic里的 platform.inc文件，直接删除里面的“-mno-cygwin”。

这里参考了http://blog.csdn.net/xi52qian/article/details/10122731

 

3.编译faac过程中出错

make[3]: *** [3gp.o] Error 1
make[3]: Leaving directory `/d/ffmpeg/faac-1.28/common/mp4v2'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/d/ffmpeg/faac-1.28/common'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/d/ffmpeg/faac-1.28'
make: *** [all] Error 2

 新建一个文件faac-1.28.diff，打开，把下面的内容复制上去

 保存，在执行$./bootstrap之前首先执行  $ patch -p1 < faac-1.28.diff

4.编译完成之后编码速度慢的问题

在第一遍编译完成后，尝试进行视频压制时出现了速度特别慢的问题。speed只能达到0.15左右，但是官网下载的share版本却能达到0.7。压制时提示libx264 using cpu capabilities none

用了很多办法，比如用最新版的yasm重新编译等等都没能解决。

最终解决办法是在编译x264的时候，网上大部分给出的config是$./configure --enable-shared --disable-asm

在这里把 --disable-asm去掉，重新编译一个libx264之后，覆盖到ffmpeg的bin目录下，重新运行之后速度就上去了
