[PATCH 1/3] drm: drm_fourcc: Add scaling and padding factor to drm_format_info

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Satish Kumar Nagireddy <satish.nagireddy.nagireddy@xxxxxxxxxx>

'cpp_scale' can be used as a multiplying factor to calculate
bytes per component based on color format.
For eg. scaling factor of YUV420 8 bit format is 1
        so multiplying factor is 1 (8/8)
        scaling factor of YUV420 10 bit format is 1.25 (10/8)

'padding_scale' can be used as a multiplying factor to calculate
actual width of video according to color format.
For eg. padding factor of YUV420 8 bit format: 8 bits per 1 component
        no padding bits here, so multiplying factor is 1
        padding factor of YUV422 10 bit format: 32 bits per 3 components
        each component is 10 bit and the factor is 32/30
