Media Source in SMFv2

Question

hi,

i have used these codes for testing SMFv2 player but my button_click event throws a exception in source setting code!

my codes:

<UserControl x:Class="SMF_Test.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:Core="clr-namespace:Microsoft.SilverlightMediaFramework.Core;assembly=Microsoft.SilverlightMediaFramework.Core" 
    xmlns:Media="clr-namespace:Microsoft.SilverlightMediaFramework.Core.Media;assembly=Microsoft.SilverlightMediaFramework.Core" 
    mc:Ignorable="d"
    d:DesignHeight="600" d:DesignWidth="800">

    <Grid x:Name="LayoutRoot" Background="White">
        <Core:SMFPlayer Height="400" Margin="48,100,91,100">
            <Core:SMFPlayer.Playlist>
                <Media:PlaylistItem x:Name="Player"/>
            </Core:SMFPlayer.Playlist>
        </Core:SMFPlayer>
        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="48,515,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
    </Grid>
</UserControl>

button click event handler:

namespace SMF_Test
{
    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            Player.MediaSource = new Uri("http://localhost:1369/ClientBin/3.wmv");
        }
    }
}

my video is in the Client Bin Folder and its build action property is Resource!

Answer 1

Player.MediaSource = new Uri("http://localhost:1369/ClientBin/3.wmv");

 

Did you try

Player.MediaSource = new Uri("3.wmv", UriKind.Relative)

Player.MediaSource = new Uri("/3.wmv", UriKind.Relative)

Player.MediaSource = new Uri("../ClientBin/3.wmv", UriKind.Relative)

Answer 2

no solve!

my exception:

"Object reference not set to an instance of an object."

Answer 3

Which object in null? 

Answer 4

{System.NullReferenceException: Object reference not set to an instance of an object.
   at SMF_Test.MainPage.button1_Click(Object sender, RoutedEventArgs e)

   at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, String eventName)}

Answer 5

Which object in null? 

 

Oops

Should have said

Which object IS null?

Answer 6

Player object

Answer 7

Put a breakpoint on this line:

Player.MediaSource = new Uri("http://localhost:1369/ClientBin/3.wmv");

 

Which object is null? Player?

Answer 8

Player object!

Answer 9

Your code is getting confused on object keywords. Change x:Name in this

<Media:PlaylistItem x:Name="Player"/>  

to something else like myPlaylistItem and then make the same change here

Player.MediaSource = new Uri("http://localhost:1369/ClientBin/3.wmv"); 

Answer 10

the same exception appear!

Answer 11

I'm trying to duplicate the error here. 

Answer 12

i have used SMFv2 and this Documentation: SMFv2

Answer 13

my source project:

SMF_Test

Answer 14

Thanks - I've been using SMFv2 since the beta came out in June. But always streaming, not locally hosted files.

I'm still working on it. 

Answer 15

The syntax you are using is not allowed in the SMFv2. What you need to do is create a new PlaylistItem and put it into the Playlist.

I added x:Name="myPlayer" to this:

<Core:SMFPlayer Height="400" x:Name="myPlayer"
                        Margin="48,100,91,100">

In code, I added these 2 using statements:

using Microsoft.SilverlightMediaFramework.Core;
using Microsoft.SilverlightMediaFramework.Core.Media;

Then this is the new code in the button click handler:

            PlaylistItem pliTemp = new PlaylistItem();
            pliTemp.MediaSource = new Uri(http://localhost:1369/ClientBin/3.wmv);
            myPlayer.Playlist[0] = pliTemp;
            myPlayer.GoToPlaylistItem(0);

Answer 16

tnx alot snelldl!

it works very well.

Answer 17

pliTemp.MediaSource = new Uri(http://localhost:1369/ClientBin/3.wmv);

 

Forgot to quote the uri!

pliTemp.MediaSource = new Uri("http://localhost:1369/ClientBin/3.wmv");
