Common web player codes

The players we see on the web are nothing more than WMP/RealPlayer/Flash Player. The others are just different panels or have other controls added. Some players installed on the computer are also the integration of encoding and decoding. The core encoding and decoding technologies are the same. For example: the most popular windows media streams on the Internet (asf, wma, wmv formats), Real streams (rm, rmvb formats), and MPEG series encoding formats (MP4, MP3 formats). The following is the common web player code compiled by admin10000.com


1. Use the Embed tag to play multimedia files
Format . The file name can be in any multimedia file format. For example, "test.wma" will display a Windows Media Player on the web page (because wma is exclusive to WMP). Another example is "test.rm". Display a Real Player player on the web page. Of course, RealPlayer must be installed on your computer to display it.
In fact, the embed tag can also display Flash animation (in this case, the role of the embed tag is similar to that of using the object tag to display Flash animation), example:
In short, to summarize the role of the embed tag: play the specified multimedia file on the web page.


2. Call Windows Media Player for playback
Can be used to play wmv, asf and other format files

<object classid="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95" codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=6,4,5,715" type="application/x-oleobject" height="200" width="300">
<param name="filename" value="test.wmv" />
<param name="autostart" value="false" />
<param name="showstatusbar" value="true" />
<param name="showtracker" value="true" />
<param name="showcontrols" value="true" />
<embed filename="test.wmv" autostart="false" pluginspage="http://www.microsoft.com/windows/windowsmedia/" showcontrols="true" showstatusbar="true" showtracker="true" src="test.wmv" type="application/x-mplayer2" height="200" width="300">embed>
object>

Windows Media Player 7 及更高版本的 class ID 是：clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6
上面例子中的 class ID 是一个老的版本，但是依然可以工作，这是因为其向后兼容性。但是如果使用了老的 class ID，就无法使用增加到组件中的新特性了。
下面给出新版本的例子

<object classid="CLSID:6BF52A52-394A-11D3-B153-00C04F79FAA6" type="application/x-oleobject" height="200" width="300">
<param name="url" value="test.wmv" />
<param name="autostart" value="false" />
<param name="showstatusbar" value="true" />
<param name="showtracker" value="true" />
<param name="showcontrols" value="true" />
<param name="uimode" value="full"/>
<embed filename="test.wmv" autostart="false" showcontrols="true" showstatusbar="true" showtracker="true" uimode="full" src="test.wmv" type="application/x-mplayer2" height="200" width="300">embed>
object>

3. Call Real Player to play
Can be used to play rm, ram and other format files

Playback box:
<object classid=clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA height =285 id=RAOCX name=rmplay width=356>
<param name=" SRC" value="Video address">
<param name="CONSOLE" value="Clip1">
<param name="CONTROLS" value=" imagewindow">
<param name="AUTOSTART " value="true">
<embed src="Video address" autostart="true" controls=" ImageWindow" console="Clip1" pluginspage="http://www.real.com" /' width="356" height="285">
embed>
object>

Control frame: can be followed closely by the play frame
<object classid=clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA height=27 id=video1 width=356 >
<param name="_ExtentX" value ="7276">
