Yes I meant about on-demand content.
My only point was, as player is pulling video & audio chunks based on bandwidth, cpu & seek-poistion etc, it could have helped me to serve metadata based on clients’ capabilities. And the way to do it was to generate the text stream dynamically.
Thanks anyways.

Are you still talking about on-demand video, or live video too?

If you don’t know what ads/comments you will need to insert ahead of time, then insert markers which correspond to some lookup scheme (e.g. DoubleClick calls).

Hi Alex,

Thanks for your answer.
I got the method you were explaining but in my scenario, if I don’t know what announcements/ads to place in advance and also what position (e.g. I need to put markers for user comments in text stream which are stored in a db) what should I do?

I basically need a way in which everytime user starts a video I should be able to create text-stream dynamically. At the same time I dont want to generate the entire ismc file at runtime.

Please help.

Hi Sushil,

I recommend you look at http://www.codeplex.com/Wikipage?ProjectName=smf because the Silverlight Media Framework is already enabled for interpreting ad insert metadata.

If you’d like to insert ad markers into pre-encoded content, you could do it by appending ad stream metadata to the client manifest (*.ismc), like this:

The string within the F tags is just a base64 encoded string formatted in a way that makes sense to your client.

Hi Duncan,

Byte range requests weren’t used because:
1) they’re not universally cacheable
2) at the time of Silverlight 2 (when Smooth Streaming was being developed) not all browser stacks supported HTTP 1.1 yet
