C Specification

To launch an encode operation that results in bitstream generation, call:

// Provided by VK_KHR_video_encode_queue
void vkCmdEncodeVideoKHR(
    VkCommandBuffer                             commandBuffer,
    const VkVideoEncodeInfoKHR*                 pEncodeInfo);

Parameters

  • commandBuffer is the command buffer to be filled with this function for encoding to generate a bitstream.

  • pEncodeInfo is a pointer to a VkVideoEncodeInfoKHR structure.

Description

Valid Usage (Implicit)
  • VUID-vkCmdEncodeVideoKHR-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdEncodeVideoKHR-pEncodeInfo-parameter
    pEncodeInfo must be a valid pointer to a valid VkVideoEncodeInfoKHR structure

  • VUID-vkCmdEncodeVideoKHR-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdEncodeVideoKHR-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support encode operations

  • VUID-vkCmdEncodeVideoKHR-renderpass
    This command must only be called outside of a render pass instance

  • VUID-vkCmdEncodeVideoKHR-videocoding
    This command must only be called inside of a video coding scope

  • VUID-vkCmdEncodeVideoKHR-bufferlevel
    commandBuffer must be a primary VkCommandBuffer

Host Synchronization
  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
