title: FFMPEG audio decoding
body: <p>I have used the avcodec_decode_audio3 function to decode the AMR content in the frame order.</p>
  
  <p>I get 640 bytes output for each frame, with sample format being float and I have saved the output as a raw output file.</p>
  
  <p>Now, I want to validate this output content. But I can't play it in any player as it does not have any header or media info. And I am not able to find any command in ffmpeg which gives me raw audio output.</p>
  
  <p>Now, if want to re-encode that raw output content in FFMPEG, what would be the input format I need to give.</p>
  
  <p>Can anybody give some suggestion on this?</p>
