Hi,
i am developing a driver off MSVAD multistr but when i tested the
sample driver on XP SP3, multiple streams are not getting created..
i am playing 3 different songs using 3 different, so as 3 streams should be
simultaneously active however, only 1 stream is created,
here's the Windbg log ( please note i am using the original sample without
any modification)
( i am commenting the log a bit )
//played first song in Media player classic
MSVAD: SaveData 854D50D8
MSVAD: New Format: 64000
MSVAD: New Format: 100
MSVAD: KSSTATE_PAUSE
MSVAD: New Format: 48000
MSVAD: KSSTATE_RUN
// played another song in vlc
MSVAD: [CMiniportTopologyMSVAD::PropertyHandlerVolume - ntStatus=0xc0000023]
MSVAD: [CMiniportTopologyMSVAD::PropertyHandlerVolume - ntStatus=0xc0000023]
MSVAD: [CMiniportTopologyMSVAD::PropertyHandlerVolume - ntStatus=0xc0000023]
// played another song in Windows media player
MSVAD: [CSaveData::FileOpen : Error opening data file]
MSVAD: [CMiniportTopologyMSVAD::PropertyHandlerVolume - ntStatus=0xc0000023]
MSVAD: [CMiniportTopologyMSVAD::PropertyHandlerVolume - ntStatus=0xc0000023]
MSVAD: [CMiniportTopologyMSVAD::PropertyHandlerVolume - ntStatus=0xc0000023]
// now all the players are shut down one by one
MSVAD: KSSTATE_PAUSE
MSVAD: KSSTATE_STOP
CMiniportWaveCyclic::NewStream ( minwave.cpp ) is callled only when no
stream is active. If only 1 stream can be active then what is the difference
of MSVAD simple and MSVAD multistr .
Can somebody throw some light as to why the sample is not working.If i am
thing right 3 media player, playing 3 songs(simulateneously in 3 different
players) should make 3 active streams. is this true???
Waiting for your ideas ( & solution)
Thanks for your help.
