问题:

I am trying to use HTTP Live Streaming (HLS) to stream video to my computers and my iPhone. After reading through the Apple 'HTTP Live Streaming Overview' as well as 'Best Practices for Creating and Deploying HTTP Live Streaming Media for the iPhone and iPad', I am a bit stuck.

I took my source file (an mkv) and used ffmpeg to encode the file the MPEG-TS format and Apple-recommended settings and a Baseline 3.0 profile:

ffmpeg -i "example.mkv" -f mpegts -threads:v 4 -sws_flags bicubic -vf "scale=640:352,setdar=16/9,ass=sub.ass" -codec:v libx264 -r 29.970 -b:v 1200k -profile:v baseline -level:v 3.0 -movflags faststart -coder 1 -flags +loop -cmp chroma -partitions +parti8x8+parti4x4+partp8x8+partb8x8 -me_method hex -subq 6 -me_range 16 -g 239 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -b_strategy 1 -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -direct-pred 1 -fast-pskip 1 -af "aresample=48000" -codec:a libvo_aacenc -b:a 96k -ac 2  -y "output.ts"

No worries there. I used a pre-compiled segmenting tool to segment the video and build a .m3u8 playlist. The resultant file looked like this:

#EXTM3U
#EXT-X-TARGETDURATION:10
#EXTINF:10,
http://localhost/media/stream/stream-1.ts
#EXTINF:10,
http://localhost/media/stream/stream-2.ts
#EXTINF:10,
http://localhost/media/stream/stream-3.ts
#EXT-X-ENDLIST

I checked that against some Example Playlist Files for use with HTTP Live Streaming, and I don't see any issues. I also tried playing the .m3u8 file in VLC, and it works like a charm.

I created an HTML page to play the file:

<html lang="en">
    <head>
        <meta charset=utf-8/>
    </head>
    <body>
        <div id='player'>
            <video width="352" height="288" src="stream.m3u8" controls autoplay>
            </video>
        </div>
    </body>
</html>

And this page does not work in Chrome, Safari, on my iPhone. The html5 video tag examples on w3schools work fine on my computer, and the official Apple overview mentioned above gives an HTML example very similar to my page. Nevertheless, my video player is completely unresponsive when I visit my own .m3u8 page.

Might be a little late with the answer but you need to supply the MIME type attribute in the video tag: type="application/x-mpegURL". The video tag I use for a 16:9 stream looks like this.

<video width="352" height="198" controls>
    <source src="playlist.m3u8" type="application/x-mpegURL">
</video>

<html>
<body>
    <video width="600" height="400" controls>
        <source src="index.m3u8" type="application/x-mpegURL">
    </video>
</body>

Stream HLS or m3u8 files using above code. it works to edge browser, chrome,opera mini (mobile browser) (not working with pc chrome)

To play on all browser use flash based media player. media player to support all browser

Adding to ben.bourdin answer, you can at least in any HTML based application, check if the browser supports HLS in its video element:

Let´s assume that your video element ID is "myVideo", then through javascript you can use the "canPlayType" function (http://www.w3schools.com/tags/av_met_canplaytype.asp)

var videoElement = document.getElementById("myVideo");
if(videoElement.canPlayType('application/vnd.apple.mpegurl') === "probably" || videoElement.canPlayType('application/vnd.apple.mpegurl') === "maybe"){
    //Actions like playing the .m3u8 content
}
else{
    //Actions like playing another video type
}

The canPlayType function, returns:

"" when there is no support for the specified audio/video type

"maybe" when the browser might support the specified audio/video type

"probably" when it most likely supports the specified audio/video type (you can use just this value in the validation to be more sure that your browser supports the specified type)

Hope this help :)

Best regards!

Use Flowplayer:

<link rel="stylesheet" href="//releases.flowplayer.org/7.0.4/commercial/skin/skin.css">
    <style>

   </style>
   <script src="//code.jquery.com/jquery-1.12.4.min.js"></script>
  <script src="//releases.flowplayer.org/7.0.4/commercial/flowplayer.min.js"></script>
  <script src="//releases.flowplayer.org/hlsjs/flowplayer.hlsjs.min.js"></script> 
  <script>
  flowplayer(function (api) {
    api.on("load", function (e, api, video) {
      $("#vinfo").text(api.engine.engineName + " engine playing " + video.type);
    }); });
  </script>

<div class="flowplayer fixed-controls no-toggle no-time play-button obj"
      style="    width: 85.5%;
    height: 80%;
    margin-left: 7.2%;
    margin-top: 6%;
    z-index: 1000;" data-key="$812975748999788" data-live="true" data-share="false" data-ratio="0.5625"  data-logo="">
      <video autoplay="true" stretch="true">

         <source type="application/x-mpegurl" src="http://live.wmncdn.net/safaritv2/live2.stream/index.m3u8">
      </video>   
   </div>

Different methods are available in flowplayer.org website.

You can use video js library for easily play HLS video's. It allows to directly play videos

<!-- CSS  -->
 <link href="https://vjs.zencdn.net/7.2.3/video-js.css" rel="stylesheet">
<!-- HTML -->
<video id='hls-example'  class="video-js vjs-default-skin" width="400" height="300" controls>
<source type="application/x-mpegURL" src="http://www.streambox.fr/playlists/test_001/stream.m3u8">
</video>
<!-- JS code -->
<!-- If you'd like to support IE8 (for Video.js versions prior to v7) -->
<script src="https://vjs.zencdn.net/ie8/ie8-version/videojs-ie8.min.js"></script>

var player = videojs('hls-example');
player.play();
