iOS上的視頻支持

Question

我已經成功構建了libyuv.a庫，但是當我運行configure-iPhone（ https://code.google.com/p/siphon/wiki/VIdeoSupport ）時，我得到了告訴libyuv不可用和禁用視頻支持的日志。 誰能告訴我如何將libyuv.a文件鏈接到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'.

您是自己構建libyuv嗎？ 如果是這樣，我也遇到了這個問題，必須這樣做：

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

或安裝libyuv的任何地方。

希望對您有所幫助，如果您仍在嘗試使其正常運行。
