Hi All, as the subject indicates, my AVStream driver bugchecks after a media seek in WinDVD (ConnectionInterface is KSINTERFACE_STANDARD_STREAMING). Reason is that the memory location referenced by the stream pointer is invalid after the seek! Prior to the seek all is fine. While seeking, the driver is set to KSSTATE_PAUSE. I had exactly the same issue with our WavePCI based drivers. In WavePCI I could fix the BSOD by releasing all mappings (PortStream->ReleaseMapping()) whenever the driver went to KSSTATE_PAUSE. Now I'm trying to do the same in AVStream. In pause state I'm deleting all clone pointers and I'm also advancing the Leading stream pointer until it fails. Of no avail. Any ideas? Thanks a lot, Stephan ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.de/
