#28 FFmpeg-java PlayerExample throws NullPointerException

When I execute PlayerExample.class file I took these errors.

Exception in thread "main" java.lang.NullPointerException
at com.sun.jna.Structure.useMemory(Structure.java:154)

at PlayerExample.main(PlayerExample.java:98)

PlayerExample source code at line:98 and 99 is:

final Pointer pCodecCtx = new AVStream(formatCtx.getStreams()[0]).codec;
final AVCodecContext codecCtx = new AVCodecContext(pCodecCtx);

This is most probably caused by different ffmpeg version ...
ffmpeg-java and ffmpeg versions do not match: avcodec_version=??? LIBAVCODEC_VERSION_INT=3355137
