[DUG] Play a movie from a stream

[Kyley Harris]

Phil. Windows Media Supports playing IStream. So using the
TStreamAdapter interface you should be able to parse and play any
tstream with valid information in it.

 

You can download the Windows Media Format SDK to get C example apps etc
on how to do all this.

look at IWMReader interface etc

 

Suffice it to say that this is how windows does all their internet media
streaming. And it probably takes a lot of reading to work out how to do
it. But that's what MSDN is for

Thanks Ben, I will take a closer look at it. As soon as I saw the
Filename and the checks on the filename in the SetFileName routine, I
dismissed it. I'll give it a go now though.

Cheers,
Phil.

there's
definately no file-based activity there. yes, you need to set a filename
in the
mediaplayer, but thats only used to identify which named-memorystream to
use as a
datasource..

  Hi Ben,
 
yes, found that before too. Works by writing to a temporary file as
faras I can tell
by looking at the source code. As I said, I spent half aday scouring the
internet.
 
Has no one done this before?

1min on google found this:
http://www.wilsonc.demon.co.uk/misccomponents.htm"TMediaPlayerMemoryFile
allows you
to play wave and AVI memory images using theregular Delphi TMediaPlayer
component. 
You can create the memory images on-the-flyor load them from
resources."looks like a
nice workaround to the mediaplayer limitation..no idea if it works.. ---
