mplayer编译参数的一个疑问

时间：2009-12-21

最近在搞linux的高清播放方案，想问一下：
--enable-libopencore_amrnb --enable-libopencore_amrwb

这两个configure参数有什么用？

FFmpeg has removed support for libamr as of svn revision 19365. It has been replaced with support for libopencore-amr. Naturally the configure options have changed. The libamr options have been removed and there are two new options to take their place:
--enable-libopencore-amrnb
--enable-libopencore-amrwb

The reason for this change is that the libamr license was non-free, while libopencore-amr is licensed under an Apache 2 license. The change was discussed at length on the developer mailing list during May, June, and July. This has several effects:
You may now distribute FFmpeg builds with support for dynamically loading libopencore-amr
Support for AMR-WB encoding has been removed since libopencore-amr does not support it

谢谢楼主，不过我想知道libamr的作用，如果我不enable会有什么影响?最近我编译支持coreavc的mplayer时，enable这两个参数会导致编译无法通过。

貌似播放 .amr/.3gp 格式要用到 libamr 的

要事先安装opencore-amr的
