    • maxSliceSegmentCount

      public int maxSliceSegmentCount()
      indicates the maximum number of slice segments that can be encoded for a single picture. Further restrictions may apply to the number of slice segments that can be encoded for a single picture depending on other capabilities and codec-specific rules.

    • maxTiles

      public VkExtent2D maxTiles()
      indicates the maximum number of H.265 tile columns and rows, as defined in sections 3.175 and 3.176 of the ITU-T H.265 Specification that can be encoded for a single picture. Further restrictions may apply to the number of H.265 tiles that can be encoded for a single picture depending on other capabilities and codec-specific rules.

    • ctbSizes

      public int ctbSizes()
      a bitmask of VkVideoEncodeH265CtbSizeFlagBitsKHR describing the supported CTB sizes.

    • transformBlockSizes

      public int transformBlockSizes()
      a bitmask of VkVideoEncodeH265TransformBlockSizeFlagBitsKHR describing the supported transform block sizes.

    • maxPPictureL0ReferenceCount

      public int maxPPictureL0ReferenceCount()
      indicates the maximum number of reference pictures the implementation supports in the reference list L0 for P pictures.
      Note

      As implementations may override the reference lists, maxPPictureL0ReferenceCount does not limit the number of elements that the application can specify in the L0 reference list for P pictures. However, if maxPPictureL0ReferenceCount is zero, then the use of P pictures is not allowed. In case of H.265 encoding, pictures can be encoded using only forward prediction even if P pictures are not supported, as the ITU-T H.265 Specification supports generalized P & B frames (also known as low delay B frames) whereas B frames can refer to past frames through both the L0 and L1 reference lists.

    • maxBPictureL0ReferenceCount

      public int maxBPictureL0ReferenceCount()
      indicates the maximum number of reference pictures the implementation supports in the reference list L0 for B pictures.

    • maxL1ReferenceCount

      public int maxL1ReferenceCount()
      indicates the maximum number of reference pictures the implementation supports in the reference list L1 if encoding of B pictures is supported.
      Note

      As implementations may override the reference lists, maxBPictureL0ReferenceCount and maxL1ReferenceCount does not limit the number of elements that the application can specify in the L0 and L1 reference lists for B pictures. However, if maxBPictureL0ReferenceCount and maxL1ReferenceCount are both zero, then the use of B pictures is not allowed.

    • maxSubLayerCount

      public int maxSubLayerCount()
      indicates the maximum number of H.265 sub-layers supported by the implementation.

    • expectDyadicTemporalSubLayerPattern

      public boolean expectDyadicTemporalSubLayerPattern()
      indicates that the implementation’s rate control algorithms expect the application to use a dyadic temporal sub-layer pattern when encoding multiple temporal sub-layers.

    • minQp

      public int minQp()
      indicates the minimum QP value supported.

    • maxQp

      public int maxQp()
      indicates the maximum QP value supported.

    • prefersGopRemainingFrames

      public boolean prefersGopRemainingFrames()
      indicates that the implementation’s rate control algorithm prefers the application to specify the number of frames of each type remaining in the current group of pictures when beginning a video coding scope.

    • requiresGopRemainingFrames

      public boolean requiresGopRemainingFrames()
      indicates that the implementation’s rate control algorithm requires the application to specify the number of frames of each type remaining in the current group of pictures when beginning a video coding scope.

    • stdSyntaxFlags

      public int stdSyntaxFlags()
      a bitmask of VkVideoEncodeH265StdFlagBitsKHR indicating capabilities related to H.265 syntax elements.
