Hi,

Is it possible to write an AVStream driver using WDF? I posted this
questions a few years back and the answer was no.

There were some code snippets on using AVStream with WDF in the Winhec 2008
presentation, and there is also some new WLP requirements for USB drivers to
be WDF compilant. So does this mean that it is now possible to use AVStream
with WDF (since many usb audio/video device would be using AVStream driver)?
If this is true, is there any info on what is the minimum KMDF version that
can support this, and any info on what can and what cannot be done with WDF
for AVStream would be appreciated.

Thanks

KS
