    • maxSliceCount

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

    • 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.

    • 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.

    • maxTemporalLayerCount

      public int maxTemporalLayerCount()
      indicates the maximum number of H.264 temporal layers supported by the implementation.

    • expectDyadicTemporalLayerPattern

      indicates that the implementation’s rate control algorithms expect the application to use a dyadic temporal layer pattern when encoding multiple temporal 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 VkVideoEncodeH264StdFlagBitsKHR indicating capabilities related to H.264 syntax elements.
