Smooth Streaming on Windows Phone 7

Read Smooth Streaming in Silverlight here

This post is walkthrough on enabling smooth streaming of media over IIS and then stream over Windows Phone 7 client. There are very good documentation available on IIS official site to have a better understanding of smooth streaming. So I am not touching theoretical concept behind smooth streaming in this post. However I have shown steps by steps to enable smooth streaming of media over IIS then to stream over Windows Phone 7 client.

Essentially there are four majors steps you need to do

  1. Enable Smooth Streaming on IIS
  2. Encode Media File .There is a point to be noted here that Windows Phone 7 [at time of writing this post] does not support variable bit rate of streaming. It does support only VC-IIS Smooth Streaming -480 VPR Smile]
  3. Publish Encoded file over IIS
  4. Play the streamed media on Windows Phone 7 using smfPlayer.

Enable Smooth streaming on IIS

You need to download and install IIS Media Services. Go to below URL to download and install IIS Media Services.

http://www.iis.net/download/SmoothStreaming

image

After successful installation, you will have a section of Media Services in IIS.

Encode Media File

To encode media for IIS smooth streaming you need Microsoft Expression Encoder 4.0 pro. If you don’t have installed that then download and install that. It comes as part of Microsoft Expression.

Step 1

Very first open Microsoft Encoder Pro 4.0. You will get prompted to choose Project type to be loaded. Select Transcoding Project and press Ok.

Step 2

In this step you need to choose the media file to be encoded and streamed over IIS. Click on File in menu and select Import.

Choose media file to be encoded and streamed.

clip_image003

 

Step 3

In right side tab select Preset option. If you are unable to find Preset tab, select windows from menu and check preset.

clip_image004

From Preset tab select Encoding for Silverlight and then select IIS Smooth Streaming. After selecting option of IIS Smooth Streaming, you can choose VBR rate of your choice.

clip_image005

After IIS Smooth streaming type doesn’t forget to click Apply button.

Step 4

There are many options available for you to configure like,

  1. Thumbnails
  2. Security
  3. Template options
  4. Output path
  5. Publish etc

You can set values for above options as per your requirement. I am going to set output path here. Make sure you have created a folder on your local derive to set as output path for the encoded media for the streaming. On my local D drive, I have created a folder called StreamDemo. So set the output path as below

clip_image001[5]

Make sure to check Sub-folder by job ID. Leave Media File name as default name.

 

Step 5

If you have set the values for everything required then go ahead and click on the Encode button in the bottom.

clip_image002

You should be getting Encoding status message as below.

clip_image003

 

After successful encoding you will get encoded media playing the browser from the local derive. Now you have encoded media file.

 

Publish Encoded File over IIS

To stream over IIS, you need to publish encoded media over IIS. Process to publish encoded media is same as publishing any other web site over IIS.

Step 1

Open IIS as administrator and add a new web site

clip_image004[5]

Step 2

In dialog box you need to provide below information

  1. Site name: Give any name of your choice
  2. Port : Choose any available port above 1024
  3. Host Name : Leave it empty
  4. Type : Http
  5. Check the check box start web site immediately.
  6. In Physical path, give the same location Encoded file is saved. In previous step while encoding media for streaming, I save file in location D:\StreamDEmo. So I am going to set Physical Path as D:\StreamDEmo.

 

image

Click Ok to create web site in IIS. So we created site StreamingMediaDemo1. Right click on that and select Manage Web Site and then browse.

image

On browsing most likely you will get forbidden error message as below,

image

Append Default.html in URL to play the media.

clip_image001[7]

Media will be played as below,

image

 

Now append wildlife.ism/manifest to the URL. This manifest file would be used in Windows Phone 7 and other clients to stream media over IIS.

Playing in Windows Phone 7

To Play media on Windows Phone 7 download below player from the CodePlex.

http://smf.codeplex.com/releases/view/63434#DownloadId=222617

After download extract the file on locally. You will have to add references of these dll in Windows Phone project. Since dll got downloaded from the web, so they would be locked. To use them in the project right click and unblock them.

Note : I would recommend to download msi file and install that to get all the required files.

Step 1

Create a Windows Phone Application

clip_image002

Choose target Windows Phone version 7.0

clip_image003[5]

Step 2

Right click and add the references. If you have run msi then you will get below references at the location,

C:\Program Files (x86)\Microsoft SDKs\Microsoft Silverlight Media Framework\v2.4\Silverlight For Phone\Bin

clip_image005

Step 3

You need to download IIS smooth client and install from below URL.

http://www.iis.net/download/smoothclient

Step 4

Right click on Windows Phone 7 project and add reference of Microsoft.web.media.smoothstreaming.dll

To locate this file on your local drive browse to C:\Program Files (x86)\Microsoft SDKs\IIS Smooth Streaming Client\v1.5\Windows Phone on 64 bit machine.

clip_image007

 

Step 5

Next we need to design Silverlight page. Open MainPage.xaml and add namespace,

image

 

And add a player on the page downloaded to play stream media as below,

clip_image001[9]

Eventually xaml will be as below with a textblock to display message and player

Mainpage.xaml

 

<phone:PhoneApplicationPage
    x:Class="Streaming.MainPage"

            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

        <!--TitlePanel contains the name of the application and page title-->
        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
            <TextBlock x:Name="ApplicationTitle" Text="MY APPLICATION" Style="{StaticResource PhoneTextNormalStyle}"/>
            <TextBlock x:Name="PageTitle" Text="page name" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
        </StackPanel>

        <!--ContentPanel - place additional content here-->

                    HorizontalAlignment="Stretch"
                                 Margin="0"
                                 VerticalAlignment="Stretch"/>

            </StackPanel>
        </Grid>
    </Grid>

    <!--Sample code showing usage of ApplicationBar-->
    <!--<phone:PhoneApplicationPage.ApplicationBar>
        <shell:ApplicationBar IsVisible="True" IsMenuEnabled="True">
            <shell:ApplicationBarIconButton IconUri="/Images/appbar_button1.png" Text="Button 1"/>
            <shell:ApplicationBarIconButton IconUri="/Images/appbar_button2.png" Text="Button 2"/>
            <shell:ApplicationBar.MenuItems>
                <shell:ApplicationBarMenuItem Text="MenuItem 1"/>
                <shell:ApplicationBarMenuItem Text="MenuItem 2"/>
            </shell:ApplicationBar.MenuItems>
        </shell:ApplicationBar>
    </phone:PhoneApplicationPage.ApplicationBar>-->

</phone:PhoneApplicationPage>

Step 6

We need to write some code on page load to create play list of streamed media and play in the player.

Mainpage.xaml .cs


using System;
using Microsoft.Phone.Controls;
using Microsoft.SilverlightMediaFramework.Core.Media;


namespace Streaming
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
            PlaylistItem item = new PlaylistItem();
            item.MediaSource = new Uri("http://localhost:9173/wildlife.ism/manifest");
            item.DeliveryMethod = Microsoft.SilverlightMediaFramework.Plugins.Primitives.DeliveryMethods.AdaptiveStreaming;
            strmPlayer.Playlist.Add(item);
            strmPlayer.Play();

        }


    }
}

Step 7

Press F5 to run the application.

Now append wildlife.ism/manifest to the URL. This manifest file would be used in Silverlight and other clients to stream media over IIS.

clip_image008

Note: In further post; I will discuss more theory of streaming manifest file.

See Video of above performed steps below ,

Streaming over Silverlight

To Play media on Silverlight download below player from the CodePlex.

http://smf.codeplex.com/releases/view/63434#DownloadId=222617

After download extract the file on locally. You will have to add references of these dll in Silverlight project. Since dll got downloaded from the web, so they would be locked. To use them in the project right click and unblock them.

Step 1

Create a Silverlight project.

clip_image010

Choose the Host application and select the version as Silverlight 4.0

clip_image011

Step 2

Right click and add the reference from the extracted file of pervious step.

clip_image002

The above are DLL of the media player you downloaded from Codeplex.

Step 3

You need to download IIS smooth client and install from below URL.

http://www.iis.net/download/smoothclient

Step 4

Right click on Silverlight project and add reference of Microsoft.web.media.smoothstreaming.dll

To locate this file on your local drive browse to C:\Program Files (x86)\Microsoft SDKs\IIS Smooth Streaming Client\v1.5\Silverlight on 64 bit machine.

        </StackPanel>
    </Grid>
</UserControl>

Step 6

We need to write some code on page load to create play list of streamed media and play in the player.

See Video of above performed steps below ,

Mainpage.xaml .cs


using System;
using System.Windows.Controls;
using Microsoft.SilverlightMediaFramework.Core.Media;

namespace SilverlightStreaming
{
    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();
            PlaylistItem item = new PlaylistItem();
            item.MediaSource = new Uri("http://dhananjay-pc:7654/wildlife.ism/manifest");
            item.DeliveryMethod = Microsoft.SilverlightMediaFramework.Plugins.Primitives.DeliveryMethods.AdaptiveStreaming;
            strmPlayer.Playlist.Add(item);
            strmPlayer.Play();
        }
    }
}

Step 7

Before pressing F5 to run application make sure you have put a ClientAccessPolicy.xml file in D:\StreamdMedia location or the Physical path of IIS website streaming the media to avoid cross domain problem.

Press F5 to run the application.

Streaming in WCF

Objective

In this article, I am going to explain various aspects of streaming of messages in WCF. For example;

  1. I/O Streams
  2. Streaming and Binding
  3. Streaming and Transport channel
  4. Stream management

Why we need Streaming?

In WCF any receiving message is delivered only once entire message has been received. What I mean here is that first message is buffered at the receiving side and once it is fully received it gets delivered to the receiving end. Main problem with this approach is that receiver end is unresponsive while message is getting buffered. So default way of message handling in WCF is ok for small size messages but for the large size messages this approach is not good. So to overcome this problem Streaming in WCF come into action.

I/O Streams

WCF uses .Net Stream class for the purpose of streaming. There are no any changes while defining contract. It simply looks like normal contracts. Below contract is returning stream and taking stream input.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.Text;

using System.IO;

namespace OneWayService

{

[ServiceContract]


public
interface
IService1

{

[OperationContract]


Stream ReturnStreamfromSeervice();

[OperationContract]


void ProcessStreamFromClient(Stream stream);

}

}

  1. Parameter could be defined either as abstract base class Stream or Subclass MemoryStream
  2. Subclasses FileStream etc are not allowed as the type of parameters.

Steaming and Binding

  1. TCP, IPC and HTTP bindings support streaming.
  2. For all the Binding streaming is disabled by default.
  3. Streaming of the message should be enabled in the binding to override the buffering and enable the streaming.
  4. TransferMode property should be set according to the desired streaming mode in the bindings.
  5. Type of TransferMode property is enum TransferMode  

TransferMode enum type

using System;

namespace System.ServiceModel

{


public
enum
TransferMode

{

Buffered = 0,

Streamed = 1,

StreamedRequest = 2,

StreamedResponse = 3,

}

}

  1. This property is defined in all the binding classes.

TransferMode property in BasicHttpBinding class.

 using System;

using System.ServiceModel.Channels;

using System.Text;

using System.Xml;

namespace System.ServiceModel

{


public
class
BasicHttpBinding : Binding, IBindingRuntimePreferences

{


public
TransferMode TransferMode { get; set; }

}

}

  1. TransferMode.Streamed supports all type of streaming modes. This supports all stream operations like receiving, returning.
  2. If you want to have buffer request and stream response TransferMode.StreamedResponse.

Configuring Streaming in Config file

<system.serviceModel>

        <services>

            <service
name=OneWayService.Service1
behaviorConfiguration=OneWayService.Service1Behavior >

                <!– Service Endpoints –>

                <endpoint
address=“”
binding=basicHttpBinding
bindingConfiguration=StreamedHttp
contract=OneWayService.IService1 >

                    

                    <identity>

                        <dns
value=localhost/>

                    </identity>

                </endpoint>

                <endpoint
address=mex
binding=mexHttpBinding
contract=IMetadataExchange/>

            </service>

        </services>

<bindings>

<basicHttpBinding>

<binding
name =StreamedHttp
transferMode =Streamed />

</basicHttpBinding>

</bindings>

        <behaviors>

            <serviceBehaviors>

                <behavior
name=OneWayService.Service1Behavior>

                                        <serviceMetadata
httpGetEnabled=true/>

                                        <serviceDebug
includeExceptionDetailInFaults=false/>

                </behavior>

            </serviceBehaviors>

        </behaviors>

    </system.serviceModel>

Increasing Message size

The default message size is 64K. But the message size in case of streaming may be very large. So default message size could be increased.

MaxReceivedMessageSize property of BasicHttpBinding class is used to increase the message size. Typical way of increasing message size is in config file.

<basicHttpBinding>

<binding
name =StreamedHttp
transferMode =Streamed
maxReceivedMessageSize =100000/>

</basicHttpBinding>

 Conclusion

I have explained all the facets related to Streaming in WCF. Thanks for reading.

Happy Coding
