Thank for your advise Mr Sauro,
But i really don't know why
IVMRMixerControl9::SetMixingPrefs
Method (Windows) doesn't work with me.
I set number of streams to 1.
I set rendering mode to
VMR9Mode_Windowless
I copy the code from MSDN and change a litter bit to apply it in my application:
DWORD dwPrefs;
m_p_mix_control_->GetMixingPrefs(&dwPrefs);
dwPrefs &= ~MixerPref9_FilteringMask;
dwPrefs |= MixerPref9_PointFiltering;
hr= m_p_mix_control_->SetMixingPrefs(dwPrefs);
==> the result is still the same. Like nothing happened.
How can I solve this?
