C Specification

Possible values of VkVideoProfileInfoKHR::videoCodecOperation, specifying the type of video coding operation and video compression standard used by a video profile, are:

// Provided by VK_KHR_video_queue
typedef enum VkVideoCodecOperationFlagBitsKHR {
    VK_VIDEO_CODEC_OPERATION_NONE_KHR = 0,
#ifdef VK_ENABLE_BETA_EXTENSIONS
  // Provided by VK_EXT_video_encode_h264
    VK_VIDEO_CODEC_OPERATION_ENCODE_H264_BIT_EXT = 0x00010000,
#endif
#ifdef VK_ENABLE_BETA_EXTENSIONS
  // Provided by VK_EXT_video_encode_h265
    VK_VIDEO_CODEC_OPERATION_ENCODE_H265_BIT_EXT = 0x00020000,
#endif
  // Provided by VK_KHR_video_decode_h264
    VK_VIDEO_CODEC_OPERATION_DECODE_H264_BIT_KHR = 0x00000001,
  // Provided by VK_KHR_video_decode_h265
    VK_VIDEO_CODEC_OPERATION_DECODE_H265_BIT_KHR = 0x00000002,
} VkVideoCodecOperationFlagBitsKHR;

Description

  • VK_VIDEO_CODEC_OPERATION_NONE_KHR indicates no support for any video codec operations.

  • VK_VIDEO_CODEC_OPERATION_DECODE_H264_BIT_KHR specifies support for H.264 video decode operations.

  • VK_VIDEO_CODEC_OPERATION_DECODE_H265_BIT_KHR specifies support for H.265 video decode operations.

  • VK_VIDEO_CODEC_OPERATION_ENCODE_H264_BIT_EXT specifies support for H.264 video encode operations.

  • VK_VIDEO_CODEC_OPERATION_ENCODE_H265_BIT_EXT specifies support for H.265 video encode operations.
