TDA4VM VISS output YUV format issues

chris du

HI Sirs/Madarm,

We've set the VISS outuput YUV format as:

FVID2_DF_YUV420SP_UV

but the acutually outpout YUV format is YUV420 NV21, not YUV420 NV12 (expected)

could you please help to provied some method to debug what's wrong with it? ex: dump some register/configure that VISS actuallly used?

Thanks,

Chris

Hi Chris,

Can you try setting NV21 output format, instead of NV12?

It looks like chroma component is getting interchanged somewhere in the pipeline. Are you using default RGB2YUV coefficients? Could you please compare it against SDK?

Can you please check RGB2YUV coefficients? Are they matching with the SDK?
