5.0 UNTARRING AND BUILDING THE SAMPLE CODE
5.1 Preparing the Linux Environment
Prior to building the Z3 sample code, certain modules are required. In Ubuntu 10.x or later, the
following command can be used to get the required modules:
sudo apt-get install bison flex mtd-utils liblzo2-dev uuid-dev zlib1g-dev
libpcre3-dev autoconf autoconf-archive automake automake1.9 automake1.9-doc
libtool libtool-doc
In Fedora, the command would be:
sudo yum install bison flex mtd-utils mtd-utils-ubi lzo-devel libuuid-
devel pcre-devel automake automake17 automake14 autoconf libtool
If you are running a 64-bit OS, it may be necessary to install some 32-bit libraries for the cross-
compiling toolchain. You can determine whether your OS is 64-bit by using the “uname –p” command.
A 64-bit OS will return “x86_64,” while a 32-bit OS will return “i386”, “i586”, or “i686”.
For 64-bit Ubuntu, you can get the necessary libraries by typing:
# sudo apt-get install ia32-libs
For 64-bit Fedora, you can type:
# sudo yum install glibc.i686
5.2 Making the Directories and Running the Make Script
The software provided will allow you to re-create the pre-installed software of the Z3-DM8169-VI-RPS
starting from the included source code.
On a PC running Linux, create a directory where the released materials are going to be located:
# mkdir /home/z3/z3-netra
Copy the released tar archive to that directory:
# cp SW-7E1-00217-01_DM8169-VI-RPS-20140506.tar.bz2 /home/z3/z3-netra
Untar the archive:
# tar -xvjf SW-7E1-00217-01_DM8169-VI-RPS-20140506.tar.bz2
*Note: Untarring could take 5 to 10 minutes.
Then go into the directory just created and run the build script:
# cd z3-netra-DM8169_VI_RPS-20140506
# ./makeall.sh

11
*Note: Building can take around 30-40 minutes. You will also need to type in the sudo password a few
times throughout the build.
The outcome of the build process should be newly created image files in the images directory. You can
confirm this by doing the following:
# cd images
# ls -alt
The result should be something like the following. Note that actual filenames, dates, and times will
differ.

7.4 Power on the Board
(7) Connect the 12V power supply and turn on the switch. If all is configured properly, you should see
the board booting up within the terminal window. After about one minute, you will see the
DM8169-VI-RPS Main Menu:
Note the local IP address and netmask (in this example, it is 192.168.81.68 and 255.255.0.0). This is the
IP address of the board. You will need this later to access the web interface.

Z3 Technology, LLC ♦100 N 8th ST, STE 250 ♦Lincoln, NE 68508-1369 USA ♦+1.402.323.0702
16
7.5 Ensure Your PC has a Proper IP Address
(8) (To be able to communicate with the board, the PC that you are communicating from needs to have
at least the same first two parts of the IP address. For example, if the board has an IP address of
192.168.81.68, your PC would need to have an address of 192.168.x.y, where x.y is anything but
81.68 (and not conflicting with whatever is on your current network). Ensure that this is the case.
If necessary, use the “P” and “Q” options in the RPS menu to modify the address / network mask
of the board to conform to your network. Note that the first two parts being the same are based
on a netmask of 255.255.0.0. If netmask were 255.255.255.0, then the first three parts of the IP
address would have to be the same.
After you are done, make note of the address you set your PC to. This will be important in the
streaming step.
7.6 Run the Web Interface to Configure Encode
(9) In your PC, run a web browser (for best results, Z3 recommends FireFox or Chrome). In this browser,
type the IP address of the board noted in step (7) (for example, if the default value is used, it
would be http://192.168.81.68). After about 3 seconds, the Encoder Settings menu should come
up:

17
(10) In this menu, confirm that Video Source is set to “HDMI1” and Audio Source is set to “Automatic”.
(11) Set “Output Format” to “MPEG-2 TS”and “Dest IP Address” to the IP address of your PC (in this
example, 192.168.0.6). Also make note of the value of “Dest Port” (should be 8888 by default):
(12) Click “Start”. After about 6 seconds, the status should change from “idle” to “Running.”

(d) Click “Start” or “Restart”
(e) After clicking “start”, the
status should change to “Running”
(a) Change format to MPEG-2 TS

7.8 Streaming RTP
Once you have UDP streaming, it is relatively simple to change to RTP streaming. All that is needed are
a change of settings and an SDP file (an example file is provided with the software release from Z3). To
stream using RTP, do the following steps:
(17) In the Encoder settings tab, click on “Stop” to stop the current encoding session.
(18) Change “Output Format” from “MPEG-2 TS” to “RTP” (see Figure 8).
(19) Change “Dest IP Address” to “225.1.2.3”.
(20) Confirm that “Dest Port” (see Figure 8) is “8888”(this will be important for the VLC
configuration).
(21) Click “Start” to start streaming.
(22) Copy the “z3-netra-multicast.sdp” file received from Z3 to your PC.
(23) Open VLC. Select “Media – Open File” and select the “z3-netra-multicast.sdp” file you just
copied.
(24) You should then see RTP video streaming on VLC:
