It's seems that program can't find some libraries that sets here in IjkMediaPlayer class:
程序似乎找不到在 IjkMediaPlayer 类中设置的一些库：
##代码##what are these libraries?
这些库是什么？
where are these libraries? ( i could not find them in projects )
这些图书馆在哪里？（我在项目中找不到它们）

回答by Pavel S.
Seems that you haven't built libraries which are required - you have to do it by yourself. Follow instructions under the header Build Androidon the page ijkplayer github link
似乎您还没有构建所需的库 - 您必须自己完成。按照页面ijkplayer github链接上的标题Build Android下的说明进行操作
After successfull build process you'll get several library files (libijkffmpeg, libijkutil, libijkadk, libijksdl, libijkplayer) which will be automatically put into ijkmediaplayer/libsfolder.
成功构建过程后，您将获得多个库文件（libijkffmpeg、libijkutil、libijkadk、libijksdl、libijkplayer），这些ijkmediaplayer/libs文件将自动放入文件夹。
I've successfully built ijkplayerlibraries under VirtualBox Ubuntu 12.04. And you'll have to install Android NDK.
我已经在VirtualBox Ubuntu 12.04下成功构建了ijkplayer库。你必须安装Android NDK。
