• Decompress the ffmpeg-0.8.1.tar.gz to the/home/pekall/Projects_private/FFmpegPlayer/lib directory
• Rename the directory/home/pekall/Projects_private/FFmpegPlayer/lib/ffmpeg-0.8.1 to/home/pekall/Projects_private/FFmpegPlayer/lib/jni

3. Compile the FFmpeg configuration script

Create the script file config. sh in the/home/pekall/Projects_private/FFmpegPlayer/lib/jni directory and add the executable permission.
