VPP can't deinterlace RGB32 frames

Hello there!

When i try to initialize VPP like this, i get the error "invalid video parameters" (MFX_ERR_INVALID_VIDEO_PARAM). This error seems to be caused by VPP output parameter "PicStruct: MFX_PICSTRUCT_PROGRESSIVE". Is it not possible to deinterlace RGB32 frames?

Hi Max, 

To de-interlacing RGB32 frames, you need to set another VPP filter to do color conversion in NV12 format. The supported FOURCC format for deinterlacer is NV12 only. 

I hope that answers your query.

Thanks,
Surbhi
