如何使用ijkplayer库 [英] how to use ijkplayer library
问题描述
我要使用ijkplayer GitHub的链接。我下载了这个，然后导入通过文件>导入>常规>现有项目到工作区偏食。之后，我有三个项目：
I'm going to use ijkplayer github link. I downloaded this and then import it to eclipse by File > Import > General > Existing Projects to Workspace. After that I have three project:
1.ijkmediaplayer ( library )
2.ijkmediawidget ( VideoView-like interface )
3.ijkmediademo ( Demo project )
当我运行ijkmediademo，错误发生，程序崩溃。我得到了错误的这些行：
When I run ijkmediademo, Error happened and program crashed. I got these lines of error:

这似乎是程序无法找到一些库，设置在这里IjkMediaPlayer类：
It's seems that program can't find some libraries that sets here in IjkMediaPlayer class:
public static void loadLibrariesOnce(IjkLibLoader libLoader) {
synchronized (IjkMediaPlayer.class) {
if (!mIsLibLoaded) {
libLoader.loadLibrary("stlport_shared");
libLoader.loadLibrary("ijkffmpeg");
libLoader.loadLibrary("ijkutil");
libLoader.loadLibrary("ijkadk");
libLoader.loadLibrary("ijksdl");
libLoader.loadLibrary("ijkplayer");
mIsLibLoaded = true;
}
}
}
什么是这些库？
在哪里这些库？ （我不能在项目中找到）
where are these libraries? ( i could not find them in projects )
如何解决这个问题？
推荐答案
看来你还没有建立所需要的库 - 你必须自己做。
按照标题下指令的构建Android 在页面上 ijkplayer GitHub的链接
Seems that you haven't built libraries which are required - you have to do it by yourself. Follow instructions under the header Build Android on the page ijkplayer github link
在全成构建过程中，你会得到几个库文件（ libijkffmpeg，libijkutil，libijkadk，libijksdl，libijkplayer 的），这将被自动放入 ijkmediaplayer /库文件夹中。
After successfull build process you'll get several library files (libijkffmpeg, libijkutil, libijkadk, libijksdl, libijkplayer) which will be automatically put into ijkmediaplayer/libs folder.
我已经成功地建立的 ijkplayer 的下的的VirtualBox的Ubuntu 12.04库的。
而且你必须安装的的Android NDK 的
I've successfully built ijkplayer libraries under VirtualBox Ubuntu 12.04. And you'll have to install Android NDK.
