C Specification

To query video coding capabilities for a specific video profile, call:

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

Parameters

  • physicalDevice is the physical device from which to query the video decode or encode capabilities.

  • pVideoProfile is a pointer to a VkVideoProfileInfoKHR structure.

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

Description

If the video profile described by pVideoProfile is supported by the implementation, then this command returns VK_SUCCESS and pCapabilities is filled with the capabilities supported with the specified video profile. Otherwise, one of the video-profile-specific error codes are returned.

Valid Usage
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 VkVideoProfileInfoKHR structure

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

Return Codes
On success, this command returns
On failure, this command returns
