HLS MP4 Independent Segments
<p>Long story short: Why HLS can't just play normal MP4 files together one after one? Why need to segment media file into .ts segments?</p>

<p><strong>Details:</strong></p>

<p>We've segmented MP4 file into mini MP4 segments (not TS), each one about 30 seconds for testing. It never plays in any HLS player, just loading all segment files then nothing happens.</p>

<p><strong>When tested with HLS.js, gives this error:</strong></p>

<blockquote>
  <p>Parsing Error:no demux matching with content found,cannot recover,
  last media error recovery failed ...</p>
</blockquote>

<p>Bitmovin Player: loads all segments of all variants and never plays any of them. just stop.</p>

<p>Tested on Chrome &amp; Firefox On Windows, Safari on Mac, Android and iPad Browsers. Never works on any of them. Are we doing anything wrong?!</p>
