Vivotek PT7137 rtsp stream to webpage using VLC plugin

One way of getting the video from Vivotek PT7137 to a webpage is by using the VLC plugin and connect the rtsp stream.

However, in current version of Chrome the VLC plugin is no longer supported. Instead it is suggested to use HTML5 to embed video, but rtsp is not supported in Chrome so it is kind of a dead end there for the moment. This solution works in for example Firefox.

In the webpage where you would like to add the stream:

<object classid=”clsid:9BE31822-FDAD-461B-AD51-BE1D1C159921″ codebase=”http://download.videolan.org/pub/videolan/vlc/last/win32/axvlc.cab” id=”vlc”>
</object>
<embed type=”application/x-vlc-plugin” pluginspage=”http://www.videolan.org” autoplay=”yes” loop=”no” width=”600″ height=”340″ target=”rtsp://USERNAME:PASSWORD@IPADDRESS:554/live.sdp” />

Replace USERNAME, PASSWORD and IPADRESS with real values for your Vivotek PT7137 camera. It might be a good idea to create an account in the Vivotek PT7137 to use from the web as the username and password will be visible for anyone who inspects the webpage source code. That said, putting the root user account and password here would be considered stupid ūüôā

Tip for Joomla users: If you include this code in a Joomla site, include {emailcloak=off} before the above, because the @-sign will trig Joomla email cloaking beliving it is an email address.

CSS background-position not working on Android Mozilla

In order to position a background image inside a div I tried to use the CSS3:

background-position: right 10px center;

The goal was to position the background image to the right of a div container, 10px from the right edge and vertically centered. This worked fine in most browsers. However, in the Android devices using the native Mozilla browser the background was positioned at 0,0 (i.e. left top).

The solution was to use:

background-position: right center;

and edit the background image where I added 10 px of extra transparent space into the image.
