Installation Types There are different ways that the Helix Media Library can be installed in terms of how the hardware used and how the services are spread. For the purposes of this document it is assumed that all of the components will be installed on a single piece of hardware which will also house both the Media Content and Database. As a first run of the Installation this set up is recommended. Different Configurations are possible but this is best implemented following a successful installation on a single piece of hardware, and with the advice of your System Supplier.

IMPORTANT Version 2.5 of the Helix Media Library is installed by using the version 1.1 installer, and is then updated using Updatemanager2_5.exe To install version 2.5, follow this guide through and then apply the update using the guidelines on Page 45

SQLEXPRESS tree in the new window that appears as below:

Right click on TCP/IP and select properties. In the pop-up dialogue change the Enabled

property to Yes:

Click on the IP Addresses tab and change the Enabled property for the 127.0.0.1 address and

the IP address you are going to assign to the HML to Yes. Also update the TCP Port under IPAll to

1433 as shown:


29

Click OK and close the reminder about restarting services.

Binding IP Addresses - IIS

By default IIS, and Helix Server will try to listen on all available IP Addresses. In order to stop the

resulting conflicts between services complete the following before setting up and running Helix

Server for the first time.

Open a command prompt, and execute the following to list the IP’s that IIS is listening on:

Netsh http show iplisten

If the IP address to be used for Helix appears in the list use the following command to remove it:

(x.x.x.x – replace with listed IP)

Netsh http delete iplisten ipaddress=x.x.x.x

N.B. At this point, even though there may be no IP address listed, run the above command with

the IP address that you want to use for the Helix server. This will ensure that IIS is not listening

on this address.

Then explicitly set the IP address which should be used for requests to IIS:

Netsh http add iplisten ipaddress=x.x.x.x

30

(Where x.x.x.x is the IP address to be used for IIS)

Now restart IIS by issuing the following commands:

net stop http /y

net start http /y

net start w3svc

Install Helix Server

Launch the Helix Server installation file and click next until you reach the dialogue requesting the

license key. At this point you will be required to select a license key file that matches the

machine ID displayed.

This can be obtained from http://pam.realnetworks.com/pam. Enter your credentials to access

the product and license key download section.


31

Accept the license agreement and choose an installation location. The default in most cases.

The next screen requests details for your Administration user name and password plus the ports

required for administration access to the system. Enter your chosen credentials.

For the administration port settings, any appropriate port not already in use can be set. For this

example we have used Admin Port: 54321 and Secure Port: 12345 for ease.

The following screen will ask for a number of ports to be used:

-Control

[8008] . These are recommended.

32

This screen allows you to enter the details that will be used in your security certificate. This

certificate is employed during HTTPS connections to the server.

Here is an overview of some of the fields that may be unfamiliar:

Org. Unit: The organizational unit will correspond to your department, e.g. Accounts

Common Name: Your domain name. For large organizations, use a wildcard before the

domain name, e.g. *.myorganization.com.

CSR Name: The name for your encrypted certificate request, e.g. Helix.

The above screen is modified for reference only, and not indicative of the installer.


33

On the next screen ensure that Helix Server will be installed as a service and proceed to the end

of the wizard. Upon clicking finish Helix Server will be installed, but not started.

Install Helix Mobile Producer

Launch the Producer installer. You will be given the option of selecting Helix Mobile Producer or

RealProducer. Select Install Helix Mobile Producer.

Similar to the Helix Server installation, a key will need to be selected to license Helix Mobile

Producer and this must match the machine ID.

34

Follow the installation wizard through until the install is complete, selecting the default values

unless otherwise necessary.

IP Address and Domain Settings

In order to run successfully, the Media Library requires 2 IP addresses and 3 host names:

IP Address Host Name Bound To

0.0.0.1 hml.domain.com IIS

0.0.0.1 hmlupload.domain.com IIS

0.0.0.2 helix.domain.com Helix Server

If the DNS entries needed aren't yet configured they can be added to the hosts file at the

following location:

C:\windows\system32\drivers\etc\

An example domain name and how to add other is explained within the hosts file and can be

edited with Notepad or any standard text editor.


35

Binding IP Addresses - Helix Server

Stop the IIS service running by opening the command prompt and issuing the following

command into the command prompt window.

net stop http /y

Start the Helix Server for the first time by going to Start -> Administrative Tools -> Services.

Helix Server or Helix Mobile Server should be showing a status of Started.

Open Helix Server Administrator using the link on the desktop and log in using the credentials

previously configured. Click on Server Setup -> IP Binding.

Click the [+] sign to add an IP address and specify the address to be used by Helix server before

clicking Apply. In this case you would enter 0.0.0.2 as per the table in the previous page.

NOTE: 127.0.0.1 is used for illustrative purposes only; you should bind whatever IP

Address is being used by Helix Server

Click the “Restart Server” button at the top right of the page to apply the change to the IP

address.

At the command prompt window start IIS using the following command:

net start http /y

net start w3svc

36

Troubleshooting – At this point the Server Administrator Web Page might say “Internet

Explorer Cannot Display the Webpage”. If you do see this message then click the yellow bar at the

top of the page and click on “Enable Intranet Settings”.


37

Install Helix Media Library

Launch the HelixMediaLibrary.exe installer. If you do not have .NET 4 installed on the server

then you will be prompted to install it. Click Install.

When it has finished downloading and installing, the installer will request a reboot of the system.

Click Yes to reboot.

38

When the server has restarted and you have logged in, you will see a message asking you if you

want to open a file. This is the Helix Media Library installer starting again. Click Run.

Click Next at the welcome screen.


39

Upon agreement with the EULA, select I accept and click Next.

Check that the prerequisites are available and can be accessed by the installer.

40

Choose your installation location for the Media Library software:

Choose your installation location for the video content (bear in mind that this will need to be a

large drive in most cases or network attached storage) for the initial installation it is

recommended that this is a Local Drive. This can be changed later in the HML Admin GUI, if you

wish to use an alternative Windows NTFS File System e.g. SAN or NAS. A separate document on

alternative deployment scenarios is available with advice on specific set-ups


41

Browse to the location of your Helix Media Library Server license that will have been provided to

you on purchase, for example, HML_Key_1.1_123456.licx. On finding a valid license, a dialog will

confirm this.

Enter the domain name assigned for the Helix Media Library front end, for example,

hml.domain.com.

Input the IP address associated with the domain name. Press TAB on the keyboard or left click to

select each subsequent input field.

IMPORTANT: hmladmin is the assigned administrator user name. Enter an administrator

password and confirm it. Remember to record this information. Click Next when complete.

42

Complete the domain name and IP details for the Helix Media Library upload and administration

web site, for example, hmlupload.domain.com.

Enter the URLs where the RealMedia and Flash H.264 content will be held. For example,

rtsp://helix.domain.com/media and rtmp://helix.domain.com/flash.

The RealMedia and Flash content delivery services (mount points) are configured later.


43

Confirm the installation location of Helix Mobile Producer.

44

Enter the details for the SQL Server, including the SA password you configured earlier during the

installation. Click Next to confirm. The details entered will be tested. If it fails to connect please

refer back to the section on configuring SQL to allow connections from the software.

Click Install to start the installation process.

A number of configuration messages will be displayed during the install.

This may take several minutes so please be patient and wait until the installation is finished.


45

Once the install is complete click Finish. Upon completion two desktop icons will be created,

Helix Media Library and Helix Media Library Administrator. These will provide access to the

web front end of the service.

Selecting the checkbox for detailed instructions in configuring the Windows Services will show

information for configuring IIS 7Service

46

Updating to Version 2.5 Unzip the Updatemanager2_5.zip Right-click the Updatemanager.exe and click Run As Administrator

Enter the administrator account credentials for the computer. These are required so that the scheduled task for the encoder is created with the sufficient privileges.

Using the button with … in it, navigate to the install directory of the Helix Media Library Click Update. The window will show the update process and then tell you when it is finished and the console window can be closed.


47

Click on Close to close the updater.

48

Create Mount Points for RealMedia and Flash Player Content

RealMedia Content

The Helix Media Library will look for the Real media content at the URL specified in the installer

wizard. For the purposes of this document this is rtsp://helix.domain.com/media, so we need

to create the media mount point.

This can be configured by logging into Helix Administrator and browsing to Server Setup ->

Mount Points and clicking [+] to add a new mount point. This should be configured to point to

the content folder specified in the installer, as shown in the example below: (add the correct

content directory to the Base Path, this was defined during the Media Library Installation).

Click Apply, confirm the changes and then select Restart Server from the top of the page.


49

Flash Player H.264 MP4 Content

As before the Media Library will look for the Flash H.264 content at the URL specified in the

installer wizard. The example URL of rtmp://helix.domain.com/flash is used, so we need to

create the flash mount point.

Add the second mount as per the instructions above, based on the example settings shown

below.

The Base Path should be configured to point to the flash content folder specified in the installer

as before.

Click Apply, confirm the changes and then select Restart Server from the top of the page.

Add HTTP Mount Point

Select Server Setup -> HTTP Delivery.

Click [+] to add a new path.

Under Edit Path, add /flash (or the flash

mount point name you specified above) and

select Apply. The HTTP Mount point must be

configured for mobile content to work.

50

URL Aliasing In order to deliver content to Android and Blackberry the files need to be referenced as .3GP instead of .MP4. Instead of moving them to a different mount point and renaming the extensions they can be aliased by Helix Server. This means that when the request comes in from a device asking for a .3GP file the Helix Server will point it to the .MP4 file instead. To set this up log into the Helix Server Administrator and open up the Server Setup menu on the left, then click on URL Aliasing.

Enter in a description for the alias and then enter the alias of _lo.3pg, then the resource it will point to, _lo.mp4. Note: Only the _lo files are aliased, as high quality will not be viewed from mobile devices. IMPORTANT: The URL Aliasing must be configured for the Blackberry and Android streaming to work


51

Configure E-Mail Server Settings

You will need to set the mail server settings within the Helix Media Library so that the relevant

parties are notified on:

Content encode success

Content encode failure

Reporting of inappropriate content to the administrator

Log onto the Upload site of the Helix Media Library, by double clicking on the Helix Media

Library Administrator icon on the desktop. Enter the hmladmin credentials you stored

earlier.

Go to Settings -> E-Mail Notifications as shown below and fill out the required details.

SMTP Server: For example post.domain.com with SMTP administrator user credentials if

authentication is required.

From e-mail address: e.g. [email protected]. This is the e-mail address that all

notifications of success or failure will come from.

Cc: address for all notifications to be copied to.

Allow reporting of offensive content: a user will have the ability to warn the administrators of

any content deemed inappropriate.

52

Customize Helix Media Library Appearance

In the administration area, selecting Settings -> Customization, the coloring, logos and text style

of the Media Library can be changed.

From here you will be able to:

Apply a new header image for the administration pages (800 pixels wide).

Apply a new header image for the user pages (800 pixels wide).

Change the navigation menu color (top) and the accompanying text.

Change the site wide font used for all body text and its color.

Change the text color, highlight and selected color of the side menu.

Apply an image to the bottom of the page (800 pixels wide).

Changes can also be made to the Mobile Web Site from this screen. Please see the user guide for

further information on this.


53

Enabling Segmentation

You can enable segmentation for the iPhone and iPad which means that when you access clips

from these devices you will be accessing the file in segments to enable smoother delivery for long

form content. When it is enabled, the Helix Server needs to be configured to allow this to happen.

Segmentation is recommended when viewing clips over 2 MB in size from the iPhone/iPad. If it is

likely that there will be heavy mobile usage with the HML it is recommended that segmentation

is enabled.

To configure the Helix Server to do this:

Before loading the Helix Server Administrator, create a directory to where you would like the

segments to be output.

Load Helix Server Administrator

Expand Server Setup and click on Mount Points. Create a new mount point to point to the

directory just created.

54

In the example above, the segments directory has been created on the root of the E:\drive. Once

the mount point is created apply the changes with the Apply button and then in the top right of

the Helix Server Administrator screen click Restart to restart the server.

Click on IP Binding and note down the IP address that the Helix Server is bound to.

Now from the menus on the left click on Content Management and then click on Media Segmentation. Change the drop-down box to Yes where it says Enable Segmentation, and for the Server Hostname put in the IP address you noted down in the step above. Click on the plus icon where it says Source Path and enter your flash mount point. Change Enable Source Path to Yes and select the destination mount point, which will be your /segments/ one.

Scroll to the bottom of the page and click Apply.


55

From the menus on the left go back up to HTTP/S Delivery under the Server Setup heading. Under HTTP Delivery click the plus icon and add the /segments/ mount point, and if not already added, the /flash/ one. Click Apply to save the changes.

56

The initial setup is now complete and ready for testing. Upload a number of clips with

varying codecs to test the upload, encoding, and email processes.

Troubleshooting

Helix Server fails to start and the Administration pages cannot be reached.

If due to existing IP conflicts you are unable to start the Helix Service, add the following lines to

the end of the rmserver.cfg file found in the Helix Server installation directory.

<!— I P B I N D I N G -->

<List Name=”IPBinding”>

<Var Address_1=”127.0.0.1”/>

</List>

Replace 127.0.0.1 with your Helix servers IP

The website reports a Service Unavailable application error.

This error normally arises from either a) conflicting versions of .NET on the system, or b) a failed

installation of .NET.

Solution:

Open a command prompt

Run: net stop w3svc

Run: net stop http /y

cd %windir%\Microsoft.Net\Framework\v4.0.30319

Run: aspnet_regiis.exe –ua

Run: aspnet_regiis.exe –i

Run: net start w3svc

Run: net start http /y

Go to Start Menu -> Administrative Tools -> Internet Information Service (IIS) Manager.

Select your server; highlight Web Service Extensions. In the right pane, make sure ASP.NET

version is set to v4.0.30319


57

IIS 32 App Support on 64 bit OS

If you are installing the software on Windows 2008 64 bit, then you may need to change the

Default App Pool so that it supports 32 bit applications before the web sites will start.

To do this open IIS Manager, expand the server name on the left-hand side and click on

Application Pools.

Right-click on the DefaultAppPool on the right-hand side and click on Advanced Settings.

Click on the drop-down box next to Enable 32-Bit Applications and change the value to True.

Then click OK.

58

Back on the main IIS page, right-click on Application pools in the left menu and click refresh. Now

try accessing the sites again.

Starting the Helix Server Administrator If when you start the Helix Server administrator you see an “Internet Explorer cannot display the web page” message, then making a change to the URL could fix this. You can replace the name of your server in the URL of the administrator page with “localhost” and this should show you the logon screen. For example, if your Helix Server Administrator page URL is: http://servername:54321/admin/index.html Try changing it so that it reads: http://localhost:54321/admin/index.html

http://servername:54321/admin/index.html

http://localhost:54321/admin/index.html


59

SQL Troubleshooting – Installing Windows PowerShell If you notice that Windows PowerShell has failed, then it means that it needs to be installed. This can be done from the Server Manager. Open the Server Manager by clicking Start, Administrative Tools, and clicking Server Manage. Click on features on the left-hand side and then on the right-hand side click Add Features.

Scroll down and select Windows PowerShell then click Next.

At the next page click Install. Once the installation is successful close the Add Features Wizard.

60

Uninstalling Helix Media Library

If an installation has previously been performed and was unsuccessful, follow the below steps to

completely remove the software before attempting a re-install. This is because to protect the

database and media content the uninstaller does not remove all components required for a re-

install to occur successfully.

To uninstall completely follow the steps below.

Run the Helix Media Library uninstaller from the Add/Remove Programs wizard.

To do this click on Start, then open Control Panel and click Programs/Programs and Features. Click on Helix Media Library in the list, then click Remove.

Click Yes at the prompt asking you whether you want to remove the Helix Media Library and it will be uninstalled.


61

Open IIS by clicking on Start, then Administrative Tools and selecting IIS. Ensure that the sites have been deleted by the installer. If they haven’t then delete them by right-clicking them one at a time and clicking Delete. Click Yes to confirm the deletion.

Check that the scheduled task has been deleted by clicking on Start, Administrative Tools then

double-clicking Task Scheduler. If there is a task there called Encoder Activity then right-click it

and click Delete. Confirm it’s deletion by clicking Yes.

Check that the VLS and ASPState databases have been removed from SQL.

To do this, click Start, All Programs, and find and open SQL Server Management Studio. Log in

using the SA password or Windows Authentication (it the Windows account has administrative

rights).

Expand the databases folder, and if you see the databases VLS or ASPState delete them by right-

clicking them and clicking delete. Confirm you are sure to delete by clicking Yes at the message.

62
