i'm trying to reset the vpp for allowing dynamic input and output resolutions. MFXVideoVPP_Reset returns MFX_ERR_NONE. RunFrameVPPAsync now returns MFX_ERR_INCOMPATIBLE_VIDEO_PARAM, which isn't even documented in the manual.
If i reset the VPP with close and init it works fine. the only difference i can see in the trace is that vpp.RunFrameVppAsync.out.Data.Locked is set to 1 instead to 0. the problem is that the close/init workaround takes quite some processing time. what am i doing wrong? is resetting the vpp actually faster?
