i made a player with evrpresenter using WPF MediaKit.
the player is working, but cpu usage is very high.
i expect low cpu usage but it is similar to cpu usage of vmr9.
i cant know why.
and i downloaded evr player sample made C++ from msdn, build and run.
the result is same.
CPU usage of c++ sample is 30~40%, too.
but when i use winform and EnhancedVideoRenderer filter, it's cpu usage is below 10%.
it means that it isn't related to how to render in WPF.
when evr presenter is working, dxva seems not to work.
i can't find evr presenter sample whis has low cpu usage.
Although using EVR Presenter, why is cpu usage not changed?
