Question

我在我的64位Ubuntu 14机器上编译FFMPEG。编译得很好，除了libvpx库，它不断抛出错误：

[AS] vp9/common/x86/vp9_subpixel_8t_ssse3.asm.o
vp9/common/x86/vp9_subpixel_8t_ssse3.asm:856: warning: label alone on a line without a colon might be in error

make[1]: *** [vp9/common/x86/vp9_subpixel_8t_ssse3.asm.o] Error 1
make: *** [.DEFAULT] Error 2

我遵循了这个指南：https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu 我不知道这个错误意味着什么，但读到用NASM编译libvpx的地方已经坏了，但我不知道如何编译它。安装1.2或1.1版没有任何区别。有什么想法吗？

用Yasm编译它就可以了：

PATH="$PATH:$HOME/bin" ./configure --prefix="$HOME/ffmpeg_build" --disable-examples
PATH="$PATH:$HOME/bin" make

假设Yasm在主目录中编译

编译libvpx for FFMPEG时的编译错误
