HTML5 uploaded videos cannot be played and compatible solutions (picture)

1. Video Analysis of reasons why it cannot be played

1. Path Wrong

<video width="100%" height="100%" controls="controls">
   <source src="images/apply.mp4" type="video/mp4"></source>
  </video>

Do not add a slash in front of images, use relative paths, do not use absolute paths

2. The video format is incorrect

Solution: Currently, the video element supports three Video formats:
Format IE Firefox Opera Chrome Safari

Ogg No 3.5+ 10.5+ 5.0+ No 
MPEG 4 9.0+ No No 5.0+ 3.0+ 
WebM No 4.0+ 10.6+ 6.0+ No

Ogg = Ogg file with Theora video encoding and Vorbis Audio encoding

MPEG4 = MPEG 4 file with H.264 video encoding and AAC audio encoding

WebM = WebM file with VP8 video encoding and Vorbis audio encoding

Note: The format must comply with the above three details Requirements, such as MPEG 4, must be H.264 video and AAC audio.

3. MP4, ogg, and webm related types are not registered in the MIME of IIS, causing IIS to be unable to recognize it.

Solution : Register MP4, ogg, and webm types in IIS. The following takes MP4 as an example, ogg and webm and so on:

1. Double-click the MIME type icon in IIS

2. Right-click-"Add a new type that IIS does not recognize

3. Add the extension and type identifier of the new type

Note: The above illustration uses .MP4 as an example. If you want the video tag to be compatible with more browsers, you need to add the following types to MIME

2. Compatibility solution

1. In this case, if the video format is correct, most We are quite satisfied with the browser compatibility results, but IE678 does not support it, and its users are still a very large group in China, so we must think of another solution to support them:

The code is as follows:

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" 
width="624" height="351" style="margin-top: -10px;margin-left: -8px;" id="FLVPlayer1"> 
<param name="movie" value="FLVPlayer_Progressive.swf" /> 
<param name="quality" value="high" /> 
<param name="wmode" value="opaque" /> 
<param name="scale" value="noscale" /> 
<param name="salign" value="lt" /> 
<param name="FlashVars" value="&MM_ComponentVersion=1&skinName=public/swf/Clear_Skin_3&
streamName=public/video/test&autoPlay=false&autoRewind=false" /> 
<param name="swfversion" value="8,0,0,0" /> 
<!-- 此 param 标签提示使用 Flash Player 6.0 r65 和更高版本的用户下载最新版本的 Flash Player。如果您不想让用户看到该提示，请将其删除。 --> 
<param name="expressinstall" value="expressInstall.swf" /> 
</object>

Some files are introduced here. In addition to videos in flv format, there are also several swf or js files, which are all generated with DW software. I don’t want to study< For those who like the object> tag, just go to DW software to generate it. If you can cleverly fuse these two pieces of code, you can get the final code that is compatible with all major browsers
So we can do this:
Use
jquery to determine whether the browser is IE (there is no need to determine the specific IE version, because higher versions of IE may not pass due to server reasons. For the time being, all IE uses the tag ), load different tags according to the version, the code is as follows:

##The code is as follows:

<script> 
if($.browser.msie){ 
document.write(&#39;<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" 
width="624" height="351" style="margin-top: -10px;margin-left: -8px;" id="FLVPlayer1">&#39;+ 
&#39;<param name="movie" value="FLVPlayer_Progressive.swf" />&#39;+ 
&#39;<param name="quality" value="high" />&#39;+ 
&#39;<param name="wmode" value="opaque" />&#39;+ 
&#39;<param name="scale" value="noscale" />&#39;+ 
&#39;<param name="salign" value="lt" />&#39;+ 
&#39;<param name="FlashVars" value="&MM_ComponentVersion=1&
skinName=public/swf/Clear_Skin_3&streamName=public/video/test&autoPlay=false&autoRewind=false" />&#39;+ 
&#39;<param name="swfversion" value="8,0,0,0" />&#39;+ 
&#39;<!-- 此 param 标签提示使用 Flash Player 6.0 r65 和更高版本的用户下载最新版本的 Flash Player。如果您不想让用户看到该提示，请将其删除。 -->&#39;+ 
&#39;<param name="expressinstall" value="expressInstall.swf" />&#39;+ 
&#39;</object>&#39;); 
}else{ 
document.write(&#39;<video width="602px" height="345px" controls="controls">&#39;+ 
&#39;<source src="public/video/test.mp4" type="video/mp4"></source>&#39;+ 
&#39;<source src="public/video/test.ogg" type="video/ogg"></source>&#39;+ 
&#39;your browser does not support the video tag&#39;+ 
&#39;</video>&#39;); 
} 
</script>

Don’t forget to introduce the jquery file before writing this code

2. JS library

media is a that can make these two tags fully compatible in the old version of IE browser JavaScriptClass Library. html5media is a very powerful JavaScript library that does not depend on any JavaScript

. After using html5media, when the browser does not support Html5, it will automatically switch to the Flash mode Flowplayer player. Although there are many web players currently, the processing code is not simple. Use html5media to enable IE6/7/8 browsers to support HTML5 audio and video tags

1、首先在页面的head部分加入如下脚本

<script src="http://api.html5media.info/1.1.6/html5media.min.js"></script>

你可以通过使用IE条件注释的方法，只在旧版IE浏览器中加载这条JS脚本。

2、然后再使用audio或video添加音频视频就行了
