博客主要围绕Android应用中FFmpeg的使用展开。指出应用需有读写存储权限，且不同设备路径有差异，应使用特定方法找实际路径。还给出解决办法，可重命名文件并放入项目指定目录，系统安装程序会自动解压可执行文件。

Your Android app must have permissions to read and write to storage, in AndroidManifest.xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />.

Another caveat is the path, /storage/emulated/0/ is not available on all devices, you should use Environment.getExternalStorageDirectory() to find the actual path.

Finally, there is an easy workaround instead of extracting ffmpeg from raw folder, rename ffmpeg to lib...ffmpeg...so and put it into directory libs/armeabi in your project.

Naturally, you will later run Runtime.getRuntime().exec(getContext().getApplicationInfo().nativeLibraryDir + "/lib...ffmpeg...so" +whatever)

System installer will unpack the executable into /data/data/your.package.full.name/lib for you automagically.
