C Specification

To query video decode or encode capabilities for a specific codec, call:

// Provided by VK_KHR_video_queue
VkResult vkGetPhysicalDeviceVideoCapabilitiesKHR(
    VkPhysicalDevice                            physicalDevice,
    const VkVideoProfileKHR*                    pVideoProfile,
    VkVideoCapabilitiesKHR*                     pCapabilities);

Parameters

  • physicalDevice is the physical device whose video decode or encode capabilities will be queried.

  • pVideoProfile is a pointer to a VkVideoProfileKHR structure with a chained codec-operation specific video profile structure.

  • pCapabilities is a pointer to a VkVideoCapabilitiesKHR structure in which the capabilities are returned.

Description

Valid Usage (Implicit)

  • VUID-vkGetPhysicalDeviceVideoCapabilitiesKHR-physicalDevice-parameter
    physicalDevice must be a valid VkPhysicalDevice handle

  • VUID-vkGetPhysicalDeviceVideoCapabilitiesKHR-pVideoProfile-parameter
    pVideoProfile must be a valid pointer to a valid VkVideoProfileKHR structure

  • VUID-vkGetPhysicalDeviceVideoCapabilitiesKHR-pCapabilities-parameter
    pCapabilities must be a valid pointer to a VkVideoCapabilitiesKHR structure

Return Codes
On success, this command returns

  • VK_SUCCESS

On failure, this command returns

  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY

  • VK_ERROR_VIDEO_PROFILE_OPERATION_NOT_SUPPORTED_KHR

  • VK_ERROR_VIDEO_PROFILE_FORMAT_NOT_SUPPORTED_KHR

  • VK_ERROR_VIDEO_PICTURE_LAYOUT_NOT_SUPPORTED_KHR
