Hi,

Is there a way to stop the VPSS from doing chroma subsampling on VOUT0?

Hi Steven,

Do you mean YUV422 to YUV444 conversion? no it is not possible to disable this operation.

Rgds,

The output is configured for yuv422spuv.

Ok. Not the answer I was hoping for but thanks.

Do you want to get YUV444 as the output?

No. YUV422.

Why? Does YUV444 bypass the chroma sampling?

If we use Color Space Convertor for 30bit output, we should be able to get YUV444, but this is really not validated..
