编译ffmpeg来支持SPEEX解码 [英] Compiling ffmpeg to support SPEEX decoding

本文介绍了编译ffmpeg来支持SPEEX解码的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在编译ffmpeg来支持Speex解码。我已经在我的shell脚本中使用以下标志--enable-libspeex启用了speex解码。我还编译了从此链接下载的speex 1.2rc1。编译后，头文件在这个路径上可用/ usr / local / include / speex。按照上述过程，当ffmpeg被编译以产生对SPEEX解码的支持时，我得到未找到的libspeex错误。
任何人都可以帮助我吗？

解决方案

gcc不在 / usr / local / include 中，或者您的动态链接器没有 / usr / local / lib 在路径中。



重新编译speex并传递 - prefix = / usr 选项进行配置。 >

I am trying to compile ffmpeg to support Speex decoding. I have enabled speex decoding using the following flag --enable-libspeex in my shell script. I have also compiled speex 1.2rc1 downloaded from this link. After compiling the header files are available on this path /usr/local/include/speex. Following the above procedure when ffmpeg is compiled to produce support for SPEEX decoding I get the error libspeex not found. Can anyone help me with this?

解决方案

Either your gcc is not looking in /usr/local/include or your dynamic linker does not have /usr/local/lib in its path.

Recompile speex and pass the --prefix=/usr option to configure.
