You can download the sources from [http://downloads.isee.biz/pub/files/tvp5151/2.6.37/media-ctl.tar.gz here]&nbsp;or access to media-ctl git from [http://git.ideasonboard.org/media-ctl.git/commit/b16cbe7bce0fd8d9d940473a2272b6b0148795c3 here].<br>  There are two modules that you will use that are not inserted into the kernel: iommu2 (tvp5151) and isp.  You have to load these kernel modules before start:<br> <pre>modprobe iommu2modprobe omap3-isp</pre> (Note: The first load order must be the iommu2 and then the omap3-isp)<br>

Use the following steps to configure analog video:
*Connect a video composite input to J501 connector from IGEPv2 Expansion (near CAN Bus) or J402 connector from IGEP BERLIN (near HDMI output)
*Connect a screen, for example HDMI monitor.
*Log into IGEPv2 (via SSH, [http://labs.isee.biz/index.php/Getting_started_with_IGEPv2#Log_into_IGEPv2_via_Ethernet_interface as shown in the previous chapter]), and run the following commands:
<pre>ssh root@192.168.5.1
</pre>
*Now you have a remote igep terminal<br>
*Refresh repositories and accept it.
<pre>zypper ref </pre>
*Install video4linux2 plugin
<pre>zypper in gst-plugins-good-video4linux2
