ok so it should be faster with 4:2:0 YUV plannar combined (shouldn't you set 2 << 8 for chroma combined thus YV?) , than interleaved 4:2:2 YUV [with V0Y1U0Y0 px sequence] ? |

tried other DEFE input formats, but there is no visible change on grayscale or the image is distorted. Should I look into CSC conversion to fix color banding? |

yes, you can try other CSC entries from the matrix table. To change input format, you also need to adjust stride and output format in gstreamer |
