Hi!

can anybody explaine how can I add some stream to ASF file?
I want to add one stream with some info to my wmv(asf) files.

I saw similar example in WMPlayer SDK called rendering.asf but I don't know
how to create my own file with additional stream.

Er. Firstly, you need a profile which supports the extra stream. Create a
Asf Writer and set the profile.
Then open up the source file with ASF Reader and connect up the outputs to
the appropriate pins of the writer.
Then add the new input file / stream to the graph and hook it up to the ASF
Writer.

If you want to do this without transcoding, you will need to use the WM
Format SDK which gives you much more control. It *may* be possible to do
it in DS, but if it is it will be very painful working out how.
