There is a web plugin from VLC. From the documentation:
To embed the plugin into a webpage, use the following template:
<embed type="application/x-vlc-plugin" pluginspage="http://www.videolan.org"
width="100" height="100" target="rtsp://yourip" />
If you are using vlc version < 2.2.0 with Internet Explorer, use instead the following <object>
template:
<object classid="clsid:9BE31822-FDAD-461B-AD51-BE1D1C159921" codebase="http://download.videolan.org/pub/videolan/vlc/last/win32/axvlc.cab"
width="100" height="100" target="rtsp://yourip" ></object>
For the declaration of tag attributes, use the tag . Here an example:
<object classid="clsid:9BE31822-FDAD-461B-AD51-BE1D1C159921" codebase="http://download.videolan.org/pub/videolan/vlc/last/win32/axvlc.cab"
width="100" height="100" target="rtsp://yourip" >
<param name="autostart" value="true" />
<param name="allowfullscreen" value="false" />
</object>
For compatibility with the mozilla plugin, you can combine both tags:
<object classid="clsid:9BE31822-FDAD-461B-AD51-BE1D1C159921" codebase="http://download.videolan.org/pub/videolan/vlc/last/win32/axvlc.cab" id="vlc">
<embed type="application/x-vlc-plugin" pluginspage="http://www.videolan.org" name="vlc" />
</object>
