title: ffmpeg - whatsapp: video format not supported
body: <p>I have two videos (.mp4) files. One uploads to whatsapp and another does not.</p>
  
  <p>Using ffmpeg I checked their properties:</p>
  
  <p>a) Properties of video which uploads:</p>
  
  <pre><code>  Duration: 00:00:56.45, start: 0.148000, bitrate: 1404 kb/s
      Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1080x1080, 1359 kb/s, 23.98 fps, 23.98 tbr, 90k tbn, 47.95 tbc (default)
      Metadata:
        handler_name    : VideoHandler
      Stream #0:1(eng): Audio: aac (HE-AACv2) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 47 kb/s (default)
      Metadata:
        handler_name    : SoundHandler
  At least one output file must be specified
  </code></pre>
  
  <p>b) video which does not upload to whatsapp (because its says format not supported)</p>
  
  <pre><code>  Duration: 00:00:56.10, start: 0.000000, bitrate: 543 kb/s
      Stream #0:0: Video: h264 (High) (H264 / 0x34363248), yuv420p, 1080x1080 [SAR 1:1 DAR 1:1], 464 kb/s, 23.98 fps, 23.98 tbr, 23.98 tbn, 47.95 tbc
      Stream #0:1: Audio: aac (LC) ([255][0][0][0] / 0x00FF), 48000 Hz, stereo, fltp, 56 kb/s
  </code></pre>
  
  <p>The difference in video I noticed:</p>
  
  <p><code>(avc1 / 0x31637661)</code>  vs <code>(H264 / 0x34363248)</code></p>
  
  <p><code>1359 kb/s</code> vs <code>464 kb/s</code></p>
  
  <p><code>90k tbn</code> vs <code>23.98 tbn</code></p>
  
  <p>What can be the reason? </p>
  
  <p>Also the second video is not being played in Android.</p>
