VLDSFromSourceFilter Howto

[Claudio]

Hi again,

Trying to gain RTSP client capability, and the component in subject should be the one to use, so, after selection of the correct DS filter, it's exposing two pins: video out/audio out, ok.
Unfortunately I cannot understand how to access filter's interface (its load method contains the rtsp url to open).
DSFromSourceFilter has no demo, any hint ?

Thanks

Claudio

I hate to bump, but a lot of views and no one answer ?_?

Please, someone could tell me how do I gain access to interface of Datastead's RTSP source filter (or any other one, for that matter) ?
I am only a step behind to make a demo and buy copies of Videolab, but for the life of me I cannot figure how to reach the Load(url, null) filter call through the component.

Please, help...
