directshow filter property problem

[aguion]

Hello,
Is there any way to change the directshow filter's property without displaying the property page? I'd like to force a Vorbis decoder to output audio in the 16 bit format.

thanks for your help

There is no standard way. It's up to the filter designer to dictate how properties of a filter are set. Many filters expose a COM interface for getting and setting properties, and the property page is just a nice GUI front-end to this interface. Check to see what interfaces the Vorbis decoder filter exposes.

Thanks, vorbis doesn't provide anything for that. but I found another way to do what I wanted. thanks anyway
