Error while decoding AAC with avcodec_decode_audio4 ()

I am trying to decode AAC with the native FFmpeg decoder and encountered an error

SSR is not implemeted. Update your FFmpeg version to newest from Git. If the      problem still occurs, it mean that your file has a feature which has not implemented.

      

        
        
        
      

    

Avcodec_decode_audio4 () function return -1163346256. Is it because of the FFmpeg version? I downloaded the generic and dev version from here . Is it relevant?

Here's the source code:

I also read this question: How to decode AAC using avcodec_decode_audio4? but no solution is provided.
