New Post: SetSource from text URL

rapuke — Thu, 23 May 2013 02:54:33 GMT

How do I pass a text url to SetSource(x,y)?
Have tried converting the text to a Uri but need a stream which I do not understand!
Can see the file examples but not just a Url.

New Post: Smooth streaming VOD hangs if network becomes unavailable during playback

ashishjain1 — Wed, 22 May 2013 05:26:29 GMT

I am building a media streaming app using playerframework. We are using smooth streaming but we are facing a problem that we are also able to reproduce with the playerframework sample available on codeplex. The application is a C#/XAML modern app on Windows 8.

The scenario is –

Start playback of smooth streaming content (SmoothPage.XAML scenario in the playerframework Windows 8 sample)
While it is playing on the screen, disconnect the network (e.g. use the charms bar to disconnect the wifi network or simply plug out the Ethernet wire).
Click the right mouse button to bring the app bar and select the back button
App hangs and program counter does not come anywhere in the code

I have tried mediafailed event, adaptivesourcefailedevent, adapativesourceupdatedevent, etc. but it simply does not come to this point, while it seems to continue to try to rebuffer.

Would anyone know how to address this?

Thanks,
Ashish

New Post: Support for smooth instream captions on Windows Phone 8

keero — Mon, 20 May 2013 14:20:36 GMT

In the example code for instream captions a propertry called InstreamCaptionsEnabled of the adaptive plugin is set to true. When trying to do this for the player on Windows Phone 8, it does not recognize the property ("Cannot resolve symbol..."). I am using version 1.8.1.0 of the Player Framework. I guess support for instream captions has not been implemented for the phone framework yet. Is there a plan for doing this?

New Post: Crash after suspension

nicolar — Mon, 20 May 2013 13:31:36 GMT

Hi,

I'm encountering a crash issue after the suspension of the app. To reproduce:

1) Watch live stream (under IIS Smooth Streaming) for at least 4 minutes
2) Lock the device
3) Wait at least 4 minutes
4) Unlock the screen

Frequently, the app crashes or has already crashed during suspension. Found on Surface RT, Acer Iconia and Samsung Ativ.

This does not happen when Visual Studio debugger is attached, thus we have no visibility of the exception throw. Neither a logger help us. The last operation logged is the suspension of the app so it seems that crash occurs there somewhere. Moreover it seems to happen only during live streaming.

My feeling is that some external dll throws an exception (Adaptive Plugin/SmoothStreaming Client/Playready Client....) but I can't understand what's wrong.

Any tip?

Thanks,
Nicola

New Post: Windows 8 - OnAcquireLicense

Flaww — Sat, 18 May 2013 13:50:38 GMT

Yes, I know that Windows 8 uses a different api.

I creating application based on the drm for a large company, in a version for iOS and Android there is no problem with drm, where everything looks something like this:

playItem.LicenseUri = "blah-licenseManager.asmx";
playITem.MediaSource = "blabla.ism.manifest";
playItem.CustomData = "<ExternalData> <userid> dada </ UserID> <Msisdn> dadada </ MSISDN> </ ExternalData>";
playITem.BeginRequestLicense ();

In version SL/WP7/WP8, overrides OnLicenseAcquire and I set CustomData and create custom headers:

request.ContentType = "application / xml";
request.Headers ["referer"] = "http://blablabla/SilverPlayer.xap";
request.Headers ["msprdrm_server_redirect_compat"] = "true";
request.Headers ["msprdrm_server_exception_compat"] = "true";

Without setting a header, always will be redirected.

How do I set the headers when sending license in PlayReady SDK if it's possible?
I look into Filder when i try send license on the server, I always be redirected, as in SL without custom headers.

timgreenfield — Fri, 17 May 2013 19:12:52 GMT

Are you still seeing this issue? Assuming you didn't modify the sample in any way, the only thing I can think of is that perhaps there was some kind of issue with the server or your internet connection at the time -- or you were running software in the background that was blocking the file from downloading. Please try again -- and possibly try on another machine if you can.

New Post: How to play online flv files ?

timgreenfield — Fri, 17 May 2013 19:07:59 GMT

flv is not supported natively by Windows 8 so unfortunately there is no easy way to make this work (the player framework relies on the platform's capabilities). Note: mp4 & wmv are both supported by Win8 out of the box.

Note: I say "easy" because technically it is possible to create your own custom Media Foundation Extension to support this. However, this is not trivial and requires intimate knowledge of the format.

Alternatively, you may be able to find a 3rd party that has already built a custom MFE and license from them; I'm not sure if such a product exists or not however so you'd have to look around.

New Post: Seeking stopped working with latest update (1.2)

timgreenfield — Fri, 17 May 2013 19:05:13 GMT

Hi Jack, I haven't fully investigated what change caused this new behavior but I think this will work for you (and be more efficient). Note the e.Canceled = true

void player_SkippingBack(object sender, SkipRoutedEventArgs e)
{
    e.Canceled = true;
    player.Source = new Uri("http://smf.blob.core.windows.net/samples/videos/wildlife.mp4");
}

void player_SkippingAhead(object sender, SkipRoutedEventArgs e)
{
    e.Canceled = true;
    player.Source = new Uri("http://smf.blob.core.windows.net/samples/videos/bigbuck.mp4");
}

Let me know if you continue to have trouble getting this to work.

New Post: How to change progress bar to progress ring in playerframework

timgreenfield — Fri, 17 May 2013 18:21:50 GMT

Here's one way to accomplish this:

Add new Xaml for BufferingView to your page or App xaml:

          <Style TargetType="mmppf:BufferingView" x:Key="BufferingViewRing">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="mmppf:BufferingView">
                            <Grid>
                                <VisualStateManager.VisualStateGroups>
                                    <VisualStateGroup x:Name="MediaStates">
                                        <VisualState x:Name="Opening">
                                            <Storyboard>

                                                    <DiscreteObjectKeyFrame KeyTime="0" Value="True"/>
                                                </ObjectAnimationUsingKeyFrames>
                                                <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Visibility" Storyboard.TargetName="ProgressIndicator">
                                                    <DiscreteObjectKeyFrame KeyTime="0:0:0.01" Value="Visible"/>
                                                </ObjectAnimationUsingKeyFrames>
                                            </Storyboard>
                                        </VisualState>
                                        <VisualState x:Name="Paused"/>
                                        <VisualState x:Name="Playing"/>
                                        <VisualState x:Name="Closed"/>
                                        <VisualState x:Name="Buffering">

                                                    <DiscreteObjectKeyFrame KeyTime="0" Value="True"/>
                                                </ObjectAnimationUsingKeyFrames>
                                                <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Visibility" Storyboard.TargetName="ProgressIndicator">
                                                    <DiscreteObjectKeyFrame KeyTime="0:0:0.01" Value="Visible"/>
                                                </ObjectAnimationUsingKeyFrames>
                                            </Storyboard>
                                        </VisualState>
                                    </VisualStateGroup>
                                </VisualStateManager.VisualStateGroups>
                                <ProgressRing Width="150" Height="150" x:Name="ProgressIndicator" IsActive="False" Visibility="Collapsed" IsHitTestVisible="False"/>
                            </Grid>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>

Then, swap out the BufferingPlugin for a new one that uses this style:

public PlayerPage()
{
    this.InitializeComponent();
    player.Initializing += player_Initializing;
}

void player_Initializing(object sender, MediaPlayerDeferrableEventArgs e)
{
    var bufferingPlugin = player.Plugins.OfType<BufferingPlugin>().First();
    player.Plugins.Remove(bufferingPlugin);
    bufferingPlugin = new BufferingPlugin();
    bufferingPlugin.BufferingViewStyle = Application.Current.Resources["BufferingViewRing"] as Style;
    player.Plugins.Add(bufferingPlugin);
}

timgreenfield — Fri, 17 May 2013 18:03:54 GMT

Windows 8 uses the PlayReady SDK instead of a LIcenseAcquirer. Please refer to the PlayReady SDK docs for more info ... or you can also take a look at the sample app we ship with the player framework (which has an example of the PlayReady SDK in use).

New Post: Infinite Loading

timgreenfield — Fri, 17 May 2013 18:01:16 GMT

In your Xaml, I see you are setting AutoPlay="False". If you set this to true, you should see playback begin and MediaStarting will get raised.

If you set AutoPlay="False" on purpose, the MediaOpened event will still fire and from there or anytime after that you can call .Play(). After calling .Play(), MediaStarting will fire.

Hope this helps, let me know if I misunderstood what you are experiencing, Tim

New Post: VisualMarkers Events

timgreenfield — Fri, 17 May 2013 17:25:43 GMT

You should add to the Markers collection instead of VisualMarkers and watch for the MarkerReached event to detect when they are reached. If you also want to show the user visual indicates of where these markers are you can either:
1) Also add corresponding VisualMarkers to the VisualMarkers collection.
2) Use the ChaptersPlugin to do #1 for you. All the Chapters plugin does is look for Markers with Type == "NAME" and add them to the VisualMarkers collection for you. Note: you can change which type string is considered a Chapter by setting ChaptersPlugin.ChapterMarkerType.

New Post: PlaybackPositionChanged event

timgreenfield — Fri, 17 May 2013 17:18:27 GMT

One more thing... you can also set MediaPlayer.UpdateInterval to a timespan. This determines how often the position is updated. By default this is set to 250 ms which might be too high for your 1 second videos. Just note: the smaller the update interval, the greater the performance penalty so be sure to test well on lower end devices if setting this manually.

New Post: PlaybackPositionChanged event

timgreenfield — Fri, 17 May 2013 17:14:36 GMT

Hi Armando, I was just wondering if you have considered doing this instead:

 m_Player.MediaEnded += m_Player_MediaEnded;

void m_Player_MediaEnded(object sender, Microsoft.PlayerFramework.MediaPlayerActionEventArgs e)
{
    m_Player.Position = m_Player.EndTime;
}

There's a very slight flicker at the end as it jumps to the beginning for a split second before jumping back to the end but it appears to accomplish what you want.

New Post: PlayReady DRM Sample Code

timgreenfield — Fri, 17 May 2013 16:44:53 GMT

Here's a smooth streaming PlayReady snippet for WP8. Note, this code looks very different than Win8 because it uses the Silverlight LicenseAcquirer instead of the PlayReady SDK.

<mmppf:MediaPlayer x:Name="player" Source="http://playready.directtaps.net/smoothstreaming/TTLSS720VC1PR/To_The_Limit_720.ism/Manifest"/>

and in code behind:

public MainPage()
{
    InitializeComponent();

    player.LicenseAcquirer = new System.Windows.Media.LicenseAcquirer()
    {
        LicenseServerUriOverride = new Uri("http://playready.directtaps.net/pr/svc/rightsmanager.asmx?PlayRight=1&UseSimpleNonPersistentLicense=1")
    };
}

New Post: Slow motion and scrubbing are not supported for Windows Phone 8?

timgreenfield — Fri, 17 May 2013 16:26:03 GMT

@bytefx, if you're trying to move to a position in the video, you can either 1) let the user do it via the UI or 2) programmatically set .Position = timespan to seek to the new position.

Regarding "adding labels to the frames", are you referering to adding visual markers to the timeline (either on it or above it) or are you referring to something more like closed captions where text appears when playback passes a certain point in the video?
If the former, take a look at the VisualMarkers collection. Note: these can also be styled.
If the later, you can use the TimelineMarkers collection and the MarkerReached event to receive programmatic notification when a position is reached.
