avshws & rwiso



Hi,

I've written firmware and modified the rwiso code for an isochronous USB camera. Streaming from camera via rwiso -g command is also ok.
In this code, I construct n (typically 2) Buffers representing consecutive frames from camera. This works quite well (images complete and correct rythm)

I'd like to include this usb part in avshws sample and idea would be to remove the "simulated" hardware and pictures by the contents of these frame buffers.

For now I've "summed" the 2 projects rwiso and avshws (just to see if it was possible), but I encounter major issues :

1) KsInitializeDriver reroute the different IRP_XXs defined in rwiso and pnp driver of this cannot be used anymore.

2) How to make the Pnp for camera working : in avshws there is no hardware defined but what is to be done to integrate the pnp detection of usb camera, and precisely at plug of it ?

Is there some samples available to describe this ?

3) Is BDA a better option for this or is it similar to avshws at it seems ?

Thank you for your help,
Best Regards
.
