# vkGetPhysicalDeviceVideoCapabilitiesKHR(3) Manual Page

## Name

vkGetPhysicalDeviceVideoCapabilitiesKHR - Query video coding capabilities

Loading… please wait.

## 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

- VUID-vkGetPhysicalDeviceVideoCapabilitiesKHR-pVideoProfile-07183
  If `pVideoProfile->videoCodecOperation` specifies a decode operation, then the `pNext` chain of `pCapabilities` must include a VkVideoDecodeCapabilitiesKHR structure

- VUID-vkGetPhysicalDeviceVideoCapabilitiesKHR-pVideoProfile-07184
  If `pVideoProfile->videoCodecOperation` is `VK_VIDEO_CODEC_OPERATION_DECODE_H264_BIT_KHR`, then the `pNext` chain of `pCapabilities` must include a VkVideoDecodeH264CapabilitiesKHR structure

- VUID-vkGetPhysicalDeviceVideoCapabilitiesKHR-pVideoProfile-07185
  If `pVideoProfile->videoCodecOperation` is `VK_VIDEO_CODEC_OPERATION_DECODE_H265_BIT_KHR`, then the `pNext` chain of `pCapabilities` must include a VkVideoDecodeH265CapabilitiesKHR structure

- VUID-vkGetPhysicalDeviceVideoCapabilitiesKHR-pVideoProfile-09257
  If `pVideoProfile->videoCodecOperation` is `VK_VIDEO_CODEC_OPERATION_DECODE_AV1_BIT_KHR`, then the `pNext` chain of `pCapabilities` must include a VkVideoDecodeAV1CapabilitiesKHR structure

- VUID-vkGetPhysicalDeviceVideoCapabilitiesKHR-pVideoProfile-07186
  If `pVideoProfile->videoCodecOperation` specifies an encode operation, then the `pNext` chain of `pCapabilities` must include a VkVideoEncodeCapabilitiesKHR structure

- VUID-vkGetPhysicalDeviceVideoCapabilitiesKHR-pVideoProfile-07187
  If `pVideoProfile->videoCodecOperation` is `VK_VIDEO_CODEC_OPERATION_ENCODE_H264_BIT_KHR`, then the `pNext` chain of `pCapabilities` must include a VkVideoEncodeH264CapabilitiesKHR structure

- VUID-vkGetPhysicalDeviceVideoCapabilitiesKHR-pVideoProfile-07188
  If `pVideoProfile->videoCodecOperation` is `VK_VIDEO_CODEC_OPERATION_ENCODE_H265_BIT_KHR`, then the `pNext` chain of `pCapabilities` must include a VkVideoEncodeH265CapabilitiesKHR structure

- VUID-vkGetPhysicalDeviceVideoCapabilitiesKHR-pVideoProfile-10263
  If `pVideoProfile->videoCodecOperation` is `VK_VIDEO_CODEC_OPERATION_ENCODE_AV1_BIT_KHR`, then the `pNext` chain of `pCapabilities` must include a VkVideoEncodeAV1CapabilitiesKHR structure

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

  - `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`

  - `VK_ERROR_VIDEO_PROFILE_CODEC_NOT_SUPPORTED_KHR`
