title: Unable to store pcm audio in .mp4 container file
body: <p>Is it possible to store a pcm audio file into .mp4 file?</p>
  
  <p>I used ffmpeg command  "ffmpeg -i tempA.wav -acodec copy temp.mp4" but unable to store it in mp4 container file.</p>
  
  <blockquote>
    <p>Input #0, wav, from 'tempA.wav':</p>
    
    <p>Duration: 00:01:36.51, bitrate: 128 kb/s</p>
  
  <pre><code>Stream #0.0: Audio: pcm_s16le, 8000 Hz, 1 channels, s16, 128 kb/s
  </code></pre>
    
    <p>[mp4 @ 0x7d70e0] Tag [1][0][0][0]/0x00000001 incompatible with output
    codec id '65536'</p>
    
    <p>Output #0, mp4, to 'temp.mp4':</p>
  
  <pre><code>Stream #0.0: Audio: pcm_s16le, 8000 Hz, 1 channels, 128 kb/s
  </code></pre>
    
    <p>Stream mapping:</p>
    
    <p>Stream #0.0 -> #0.0</p>
    
    <p>Could not write header for output file #0 (incorrect codec parameters
    ?)</p>

  <p>Where in converting to <strong>.AVI</strong> (ffmpeg -i tempA.wav -acodec copy temp.avi) 
  &amp; <strong>.MOV</strong> (ffmpeg -i tempA.wav -acodec copy temp.mov) file formats works perfectly fine.</p>
