Mirroring not working

[Prasad__Nagendra]

Hi,

I am trying mirroring image using mediasdk version 2017_R3

here is mycode..

mfxExtVPPMirroring mirroringConfig;
memset(&mirroringConfig, 0, sizeof(mirroringConfig));
mirroringConfig.Header.BufferId = MFX_EXTBUFF_VPP_MIRRORING;
mirroringConfig.Header.BufferSz = sizeof(mfxExtVPPMirroring);
mirroringConfig.Type = MFX_MIRRORING_HORIZONTAL;

mfxExtBuffer* ExtBuffer = (mfxExtBuffer*) &mirroringConfig;
vppParams.NumExtParam = 1;
vppParams.ExtParam = (mfxExtBuffer**) &ExtBuffer;

where as Rotation works

mfxExtVPPRotation rotationConfig;
memset(&rotationConfig, 0, sizeof(rotationConfig));
rotationConfig.Header.BufferId = MFX_EXTBUFF_VPP_ROTATION;
rotationConfig.Header.BufferSz = sizeof(mfxExtVPPRotation);
rotationConfig.Angle = 180;

any help is appreciated..

Thanks.

Hi Prasad,

Could you run our sample code "sample_vpp" to see if you can reproduce?

sample_vpp has an argument to do "mirroring", you can refer to following document to see how to use it:
