Seek issue with ffmpeg

I implemented one audio player using with ffmpeg for playing all format audio files in android.I used following code for seek the song.

         int64_t seekTime = av_rescale_q(seekValue * AV_TIME_BASE,
                    AV_TIME_BASE_Q,
                    fmt_ctx->streams[seekStreamIndex]->time_base);

            int64_t seekStreamDuration =
                    fmt_ctx->streams[seekStreamIndex]->duration;

            int flags = AVSEEK_FLAG_BACKWARD;
            if (seekTime > 0 && seekTime < seekStreamDuration)
                flags |= AVSEEK_FLAG_ANY;

            int ret = av_seek_frame(fmt_ctx, seekStreamIndex, seek_target,
                    flags);

            if (ret < 0)
                ret = av_seek_frame(fmt_ctx, seekStreamIndex, seekTime,
                        flags);

          avcodec_flush_buffers(dec_ctx);

Its working fine for most of the songs.But some of the mp3 songs getting duration problem.For example if the song length is 2 mins if i seek the song to some position then finally song ends with 2 mins 10 seconds.I get this issue with only mp3 songs.Without seeking the same song ends with exact time. I am using ffmpeg 2.1 The some code working fine with ffmpeg 0.11.1 Please provide any information about this issue.
