Playing Real Video Movies
The <object> element can play Real Video movies.
The Real Video Format
The RealVideo format is developed by Real Media. Videos stored in the Real Video format have the extension .rm or .ram.
The format allows streaming of video (on-line video, Internet TV) with low
bandwidths. Because of the low bandwidth priority, quality is often reduced.
The Solution
This is the code required to play a Real Video movie:
<object width="320" height="240"
classid="clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA">
<param name="controls" value="ImageWindow" />
<param name="autostart" value="true" />
<param name="src" value="male.ram" />
</object>
|
The <object> Element
The width and height attributes of the object element should
match the size of the movie in pixels.
The classid attribute uniquely identifies the player software to use.
It must be set
to "clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA". This unique code
identifies an ActiveX control that must be installed on the users PC before the
movie can be played. If the user does not have the ActiveX control installed,
the browser can automatically download and install it.
The param elements supply additional information to the player.
The src parameter should point to the movie (or audio) file.
The autostart parameter should have the value "true" if you want the
movie to play automatically.
The controls parameter should have the value "ImageWindow" if you
don't want the control buttons to show, or "All" if you want all the controls to
show.
