## C Specification

The `VkVideoEncodeSessionRgbConversionCreateInfoVALVE` structure is defined as:

    // Provided by VK_VALVE_video_encode_rgb_conversion
    typedef struct VkVideoEncodeSessionRgbConversionCreateInfoVALVE {
        VkStructureType                                  sType;
        const void*                                      pNext;
        VkVideoEncodeRgbModelConversionFlagBitsVALVE     rgbModel;
        VkVideoEncodeRgbRangeCompressionFlagBitsVALVE    rgbRange;
        VkVideoEncodeRgbChromaOffsetFlagBitsVALVE        xChromaOffset;
        VkVideoEncodeRgbChromaOffsetFlagBitsVALVE        yChromaOffset;
    } VkVideoEncodeSessionRgbConversionCreateInfoVALVE;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `rgbModel` is the used R′G′B′ model conversion for the R′G′B′ conversion.

- `rgbRange` is the used R′G′B′ range compression for the R′G′B′ conversion.

- `xChromaOffset` describes the output location of downsampled chroma components in the x dimension for the R′G′B′ conversion.

- `yChromaOffset` describes the output location of downsampled chroma components in the y dimension for the R′G′B′ conversion.

## Description

Valid Usage

- VUID-VkVideoEncodeSessionRgbConversionCreateInfoVALVE-rgbModel-10930
  `rgbModel` must only be a bit set in VkVideoEncodeRgbConversionCapabilitiesVALVE::`rgbModels` as returned by vkGetPhysicalDeviceVideoCapabilitiesKHR with `VkVideoEncodeRgbConversionCapabilitiesVALVE` in the `pNext` chain of `VkVideoCapabilitiesKHR` with the given `pVideoProfile`

- VUID-VkVideoEncodeSessionRgbConversionCreateInfoVALVE-rgbRange-10931
  `rgbRange` must only be a bit set in VkVideoEncodeRgbConversionCapabilitiesVALVE::`rgbRanges` as returned by vkGetPhysicalDeviceVideoCapabilitiesKHR with `VkVideoEncodeRgbConversionCapabilitiesVALVE` in the `pNext` chain of `VkVideoCapabilitiesKHR` with the given `pVideoProfile`

- VUID-VkVideoEncodeSessionRgbConversionCreateInfoVALVE-xChromaOffset-10932
  `xChromaOffset` must only be a bit set in VkVideoEncodeRgbConversionCapabilitiesVALVE::`xChromaOffsets` as returned by vkGetPhysicalDeviceVideoCapabilitiesKHR with `VkVideoEncodeRgbConversionCapabilitiesVALVE` in the `pNext` chain of `VkVideoCapabilitiesKHR` with the given `pVideoProfile`

- VUID-VkVideoEncodeSessionRgbConversionCreateInfoVALVE-yChromaOffset-10933
  `yChromaOffset` must only be a bit set in VkVideoEncodeRgbConversionCapabilitiesVALVE::`yChromaOffsets` as returned by vkGetPhysicalDeviceVideoCapabilitiesKHR with `VkVideoEncodeRgbConversionCapabilitiesVALVE` in the `pNext` chain of `VkVideoCapabilitiesKHR` with the given `pVideoProfile`
