C Specification
The codec operations are defined with the VkVideoCodecOperationFlagBitsKHR enum:
// Provided by VK_KHR_video_queue
typedef enum VkVideoCodecOperationFlagBitsKHR {
VK_VIDEO_CODEC_OPERATION_INVALID_BIT_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
#ifdef VK_ENABLE_BETA_EXTENSIONS
// Provided by VK_EXT_video_decode_h264
VK_VIDEO_CODEC_OPERATION_DECODE_H264_BIT_EXT = 0x00000001,
#endif
#ifdef VK_ENABLE_BETA_EXTENSIONS
// Provided by VK_EXT_video_decode_h265
VK_VIDEO_CODEC_OPERATION_DECODE_H265_BIT_EXT = 0x00000002,
#endif
} VkVideoCodecOperationFlagBitsKHR;Description
Each decode or encode codec-specific extension extends this enumeration with the appropriate bit corresponding to the extension’s codec operation:
-
VK_VIDEO_CODEC_OPERATION_INVALID_BIT_KHR- No video operations are supported for this queue family. -
VK_VIDEO_CODEC_OPERATION_ENCODE_H264_BIT_EXT- H.264 video encode operations are supported by this queue family. -
VK_VIDEO_CODEC_OPERATION_DECODE_H264_BIT_EXT- H.264 video decode operations are supported by this queue family. -
VK_VIDEO_CODEC_OPERATION_DECODE_H265_BIT_EXT- H.265 video decode operations are supported by this queue family.
