VkVideoEncodeRgbConversionCapabilitiesVALVE

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:

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

pub struct VideoEncodeRgbConversionCapabilitiesVALVE {
    s_type: vk::StructureType,
    p_next: *mut c_void,
    rgb_models: vk::VideoEncodeRgbModelConversionFlagsVALVE,
    rgb_ranges: vk::VideoEncodeRgbRangeCompressionFlagsVALVE,
    x_chroma_offsets: vk::VideoEncodeRgbChromaOffsetFlagsVALVE,
    y_chroma_offsets: vk::VideoEncodeRgbChromaOffsetFlagsVALVE,
}

• 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.
