iOS上的视频支持

Question

我已经成功地构建了libyuv.a库，但是当我运行configure-iPhone(https://code.google.com/p/siphon/wiki/VIdeoSupport)时，我得到了日志，它告诉我libyuv不可用，视频支持被禁用。谁能告诉我如何将libyuv.a文件链接到configure-iPhone

Configurations for current target have been written to 'build.mak', and 'os-auto.mak' in various build directories, and pjlib/include/pj/compat/os_auto.h.

Further customizations can be put in:
  - 'user.mak'
  - 'pjlib/include/pj/config_site.h'

The next step now is to run 'make dep' and 'make'.

你在自己构建libyuv吗？如果是这样的话，我也遇到了这个问题，并不得不这样做：

ln -s /usr/local/include/libyuv/libyuv /usr/local/include/libyuv/libyuv/

或安装libyuv的位置。

希望这会有所帮助，如果你还在努力让它工作的话。
