Hi.
I'm trying run application that depends on Xv, it runs on eMenlow Pulsbo
HW. I
tried to run the XV testcode from attached file zvmon.c, but it returns an
error.
Is there another driver that needs to be installed to get XvPutVideo
support?
I used XvPutVideo in ati graphic drivers.
Best Regards.
Steven.
