# VkVideoEncodeRgbConversionCapabilitiesVALVE(3) Manual Page

## Name

VkVideoEncodeRgbConversionCapabilitiesVALVE - Structure describing video encode rgb conversion capabilities for a video profile

## C Specification

When calling vkGetPhysicalDeviceVideoCapabilitiesKHR with `pVideoProfile->videoCodecOperation` specifying an encode operation, the VkVideoEncodeRgbConversionCapabilitiesVALVE structure can be included in the `pNext` chain of the VkVideoCapabilitiesKHR structure to retrieve capabilities specific to video encode R′G′B′ conversion.

The `VkVideoEncodeRgbConversionCapabilitiesVALVE` structure is defined as:

    // Provided by VK_VALVE_video_encode_rgb_conversion
    typedef struct VkVideoEncodeRgbConversionCapabilitiesVALVE {
        VkStructureType                               sType;
        void*                                         pNext;
        VkVideoEncodeRgbModelConversionFlagsVALVE     rgbModels;
        VkVideoEncodeRgbRangeCompressionFlagsVALVE    rgbRanges;
        VkVideoEncodeRgbChromaOffsetFlagsVALVE        xChromaOffsets;
        VkVideoEncodeRgbChromaOffsetFlagsVALVE        yChromaOffsets;
    } VkVideoEncodeRgbConversionCapabilitiesVALVE;

## Members

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

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

- `rgbModels` is a bitmask of VkVideoEncodeRgbModelConversionFlagBitsVALVE describing supported model conversions for video encode R′G′B′ conversion.

- `rgbRanges` is a bitmask of VkVideoEncodeRgbRangeCompressionFlagBitsVALVE describing supported range compressions for video encode R′G′B′ conversion.

- `xChromaOffsets` is a bitmask of VkVideoEncodeRgbChromaOffsetFlagBitsVALVE describing supported offsets of the output location of the downsampled chroma component on the X axis for video encode R′G′B′ conversion.

- `yChromaOffsets` is a bitmask of VkVideoEncodeRgbChromaOffsetFlagBitsVALVE describing supported offsets of the output location of the downsampled chroma component on the Y axis for video encode R′G′B′ conversion.

## Description

Valid Usage (Implicit)
