android - 如何在 Ubuntu 中为 Android 构建 stagefright-plugins

Question

我尝试在 Ubuntu ( https://github.com/omxcodec/stagefright-plugins )中为 Android 编译 stagefright-plugins但我的步骤有问题：

    you should merge my android_frameworks_native(branch: cm_maguro-10.1) and
   android_frameworks_av(branch: cm_maguro-10.1) code. once you do, you should pay attention to
   the "USES_NAM" flag, it is only in the "android/frameworks/native" and "android/frameworks/av"
   directories.

我在“android/frameworks/native”和“android/frameworks/av”目录中找不到“USES_NAM”标志。我也看不到“android/frameworks/native”和“android/frameworks/av”目录。你能帮我解决这个问题吗？提前致谢
