Seeking problem

[Joe Giese]

We are having seek problem. Although the stream server allows seeking, the Telerik media player will freeze if manually seek forward. Please help.

Hi Martin Herrman,

Can you please download the current beta version of the media player and let us know if the problem is still reproducible. If so - can you send us the url of the stream that you are using.

Thanks!

Valentin,

Where is the beta download? Also, our mms urls are internal and it is not public.

Thanks

Hi,

New version did not work and I think now I start having bigger problem than before. Seeking does not work using telerik and will cause the freezing. I have to kill the browser. I am able to use windows media and be able to seek forward or backward.

I can't autoplay the video.

RadMediaPlayer1.SelectedIndex = 0;




and I have only one item in my media list



            RadMediaPlayer1.SelectedIndex = -1;
            if (e.Result.Count == 0)
                return;

            var items = e.Result;
            ObservableCollection<RadMediaItem> itemsSource = new ObservableCollection<RadMediaItem>();

            foreach (OnlineTraining item in items)
            {
                RadMediaItem media = new RadMediaItem();

                media.Source = new Uri(item.FileName, UriKind.RelativeOrAbsolute);
                media.Title = item.Title;
                media.Header = item.Title;
                media.Description = item.Description;
                media.VideoStretch = Stretch.None;
                media.IsStreamingSource = true;
                QuizID = item.QuizID;
                AllowBackward = item.AllowBackward;
                AllowForward = item.AllowForward;
                AllowPause = item.AllowPause;
                AllowSeek = item.AllowSeek;

                media.ImageSource = new System.Windows.Media.Imaging.BitmapImage(new Uri(item.ImageSource, UriKind.RelativeOrAbsolute));
                ObservableCollection<Chapter> chapters = item.Chapters;
                foreach (Chapter chap in chapters)
                {
                    RadMediaChapter chapter = new RadMediaChapter();
                    string[] timespan = chap.Position.Split(':');
                    chapter.Position = new TimeSpan(Convert.ToInt32(timespan[0]), Convert.ToInt32(timespan[1]), Convert.ToInt32(timespan[2]));

                    chapter.Content = chap.Title;
                    chapter.Tag = chap.ChapterID.ToString();
                    media.Items.Add(chapter);
                }

                
                itemsSource.Add(media);
                
                RadMediaPlayer1.SelectedItem = media;
            }
            RadMediaPlayer1.ItemsSource = itemsSource;
            RadMediaPlayer1.SelectedIndex = 0;

Hello Martin Herrman,

You can use RadMediaPlayer in two different ways:

• set ItemsSource to collection of custom obects - you need to provide DataTemplate to be used for the items that will be created. See example here.
• or add RadMediaItems to the Items collection. See example here.

In the snipped you provide you should go with Items collection and not ItemsSource.
About seeking - the RadMediaPlayer is wrapper around the standard Silverlight MediaElement, so it's about if the MediaElement support it. Can you please give us the url to the video so we can test it?

The URL is internal and its something like this:

mms://hortensia.ad.ocsd.local:8081/xyz.wmv

Hello Martin Herrman,

Thank you for the details. Silverlight MediaElement actually doesn't support "real" streaming even when using with mms (it'll fallback to http) - more on this here, this means that when seeking you have to wait for http downloading the video and etc. Windows Media Player won't fallback and this way you'll have real streaming. If you need real streaming you can think of using Smooth Streaming media, which is supported by RadMediaPlayer.
If you have further questions please contact us.
