推荐答案

改变是，你不能，你不应该。首先，您需要了解.so的含义。这是共享对象，可执行文件，在Microsoft域中称为DLL的东西。该文件具有特定OS的可执行文件格式，并将已编译的某些库的代码呈现给目标CPU的目标指令集。大多数可执行文件格式在许多操作系统之间共享，但存在差异。您只能使用此.so如果有人将其构建为您的确切系统。我不确定是不是这样。



关于共享对象的使用，请参阅：

To在你的程序中使用FFMPeg（我没有提到在单独的进程中只产生一个实用程序的明显可能性;如果你在询问），你需要一些C / C ++编程。请参阅：

http://developer.android.com/tools/sdk /ndk/index.html [ ^ ]。



你可以考虑这个编译器和IDE： https://play.google.com/store/apps/details?id=com.n0n3m4.droidc [ ^ ]。



然后，您可以使用FFMPeg或libavcodec（FFMpeg包含）的源代码：

http： //en.wikipedia.org/wiki/Ffmpeg [ ^ ]，

http://ffmpeg.org/ [ ^ ]，

http://en.wikipedia.org/wiki/Libavcodec [ ^ ]，

http://libav.org/ [ ^ ]。

Changes are, you cannot and you should not. First of all, you need to understand what ".so" means. This is "shared object", executable file, same thing called "DLL" in Microsoft domain. The file has the executable file format of the particular OS and presents the code of some library already compiled to the target instruction set of a target CPU. Most executable file formats are shared between many OS, but there are differences. You can only use this .so if someone has built it targeting your exact system. I'm not sure if this is the case or not.

On the use of shared objects, please see:
http://www.cplusplus.com/forum/unices/33532[^],
http://www.akkadia.org/drepper/dsohowto.pdf[^],
http://stackoverflow.com/questions/58058/using-c-classes-in-so-libraries[^].

To use FFMPeg in your program (I am not mentioning apparent possibility of spawning just a utility in a separate process; if you are asking about ), you need at some C/C++ programming. Please see:
http://developer.android.com/tools/sdk/ndk/index.html[^].

You could consider this compiler and IDE: https://play.google.com/store/apps/details?id=com.n0n3m4.droidc[^].

And then, you can use the source code of FFMPeg or libavcodec (which FFMpeg includes):
http://en.wikipedia.org/wiki/Ffmpeg[^],
http://ffmpeg.org/[^],
http://en.wikipedia.org/wiki/Libavcodec[^],
http://libav.org/[^].

Good luck,
