AVstream minidriver sample avshws in wdk7600 can't be playing as many ksproxy object RRS feed

  • Question

  • I just build the sample(avshws,which is one of avstream minidrivers samples) without modifying.

      In graphedit, i insert two object of the avstream minidriver(avshws ) into one graph,and then render them.They both connect the default render filter successfully.But when play the graph, the first object of the minidriver is ok,but the second cann't play,and the graphedit show a alert dialog,"another pragrammer is using this file, process can't access, err code:0x80070020"

          So why,is there any property not setted?
