Maybe just a TWebBrowser (preferably using the Edge/WebView2 engine) is an option?

Perhaps this might work for showing videos, but there is also the possibility that certain Codecs or Plugins were missing, like  HLS (.m3u8) : 

var
  HTMLContent: string;
begin
  HTMLContent := '<!DOCTYPE html>' +
                 '<html>' +
                 '<body>' +
                 '<video width="640" height="480" controls>' +
//either local file
                   '<source src="file:///C:/Pfad/zum/Video.mp4" type="video/mp4">' +
//or stream          
                 '<source src="https://example.com/stream.m3u8" type="application/x-mpegURL">' +  
                 'Dein Browser unterstützt das Video-Tag nicht.' +
                 '</video>' +
                 '</body>' +
                 '</html>';
  EdgeBrowser1.NavigateToString(HTMLContent);
end;

For accessing local files, there could be the need to add AdditionalBrowserArgument flags

There's the old TMediaPlayer but AFAIR it's a pain (but possible) to get to work with TStream.

 

A better alternative would be to import the type library for the Windows Media Player ActiveX and use that.

Neither currently allows a stream outside of a server side video.....

I need the ability to do this locally, without any file.  For example, the same way you can load an image from a stream. 

The videos are small and are stored as proprietary objects.

They are extracted to a MemoryStream.  To play them I currently have to write them to a file (Memorystream.savetofile) and then load them in a player (WindowsMediaPlayer.URL).  I'm looking for something to cut out the write to file
