B4J Question WebView - YouTube error ?

Patent · Sep 2, 2019

Dear Community,

wanna play a Youtube Video in a B4J WebView:

B4X:

    Dim mywebview As WebView
    mywebview.Initialize("myww")
    MainForm.RootPane.AddNode(mywebview,100,100,500,800)
    mywebview.Visible=True

    mywebview.LoadHtml( _
    $"<!DOCTYPE html>
<html>
<body>
<iframe width="420" height="345" src="https://www.youtube.com/embed/QVHhnDdjlfo">
</iframe>
</body>
</html>"$)

this gets the error: Video not available.... (first frame is visible for 0.5sec!)

same code in i.e. Firefox Browser works.

Any ideas?

Works fine. Tested with this code:

B4X:

Sub Process_Globals
   Private fx As JFX
   Private MainForm As Form
   Private WebView1 As WebView
End Sub

Sub AppStart (Form1 As Form, Args() As String)
   MainForm = Form1
   MainForm.RootPane.LoadLayout("1") 'Load the layout file.
   MainForm.Show
   WebView1.LoadUrl("https://www.youtube.com/watch?v=vog7PmCPG5w")
End Sub

Thank you Erel.
You are right, but i want to do it with HTML to get more control about the "design" of the player.

this video-id is not working:
<iframe width="560" height="315" src="https://www.youtube.com/embed/QVHhnDdjlfo" frameborder="0"
allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

this works:
<iframe width="560" height="315" src="https://www.youtube.com/embed/Iukmp8INeO8" frameborder="0"
allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

Maybe it is because of "embeding" settings. But it should not.

Any possibility to get more control with the ...LoadUrl solution?

All of this is handled by the JavaFX WebView engine.
