Play Flask Video Feed in UWP Application using WebView/Media Source - flask
I'm attempting to stream a video feed in a UWP application from a webpage created on another machine using flask. The page loads in MS Edge however when the webView is pointed to the page it gets stuck perpetually on the spinning wheel.
In the appxmanifest I've enabled Private Networks(Client & Server), Internet(Client & Server),
and Internet(Client).
I've also tried loading the page using a media player source pointed at the address which throws an error for an invalid address format.
The source for the webpage that I am attempting to load is the following:
<html>
<head>
<title></title>
</head>
<body>
<img src="/video_feed">
</body>
</html>
Any advice on what type of object I should be using to try and display the video feed would be much appreciated.
Thanks!
Edit:
Below is the source code and xaml for the page that is attempting to use the webView. Currently the image updates at 20 frames per second but this is likely to increase.
Thanks for your help.

To keep the yellow background when an alternate record is selected, set the CellValuePresenter background to Transparent. Something like this should do the trick.

Just looking at the error I would assume that, there is an error converting internal data item from Date type to external data item of Calendar data type.
Please find a sample of such conversion in bssv
public Calendar setCalendar(Date date)
{
Calendar cal = Calendar.getInstance();
if (date != null)
{
cal.setTime(date);
}
return cal;
}
Custom control binding to a collection within a property
I stuggeling with the databinding with in a custom control
I've got some properties within my custom control.
public static DependencyProperty TitleProperty;
public static DependencyProperty PageDictionaryProperty;
public string Title
{
get
{
return (string)base.GetValue(TitleProperty);
}
set
{
base.SetValue(TitleProperty, value);
}
}
public Innax.ManualParts.PageDictionary PageDictionary
{
get
{
return (Innax.ManualParts.PageDictionary)base.GetValue(PageDictionaryProperty);
}
set
{
base.SetValue(PageDictionaryProperty, value);
}
}
binding to the table isn't a problem. this works fine
but now i want to bind to the keyword property within the pageDictionary.
public class PageDictionary
{
//some other properties....
public List<string> Keywords
{
get
{
return GetKeyWords();
}
}
}
This is the XAML file.

if anyone could help me with this...
In your case the PageDirectory class need to implement INotifyPropertyChanged interface. Each time the keyword inside changed you need to raise a PropertyChanged event like this:
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs("Keywords"))
The binding string then will have view like this:
{Binding Keywords, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type local:PageDictionary}}}
Where local is namespace declared upper in the xaml for access PageDictionary type.
