D3D12DDI_VIDEO_DECODE_INPUT_STREAM_ARGUMENTS_0032 structure

Description

Video decode input stream arguments.

Members

`FrameArguments`

The arguments to decode each frame.

`NumFrameArguments`

The count of frame arguments.

`ReferenceFrames`

The reference frames needed for decoding this frame. See D3D12DDI_VIDEO_DECODE_REFERENCE_FRAMES.

`CompressedBitstream`

The compressed bitstream. All source video slices should be placed contiguously (one after another) in this buffer. See D3D12DDI_VIDEO_COMPRESSED_BITSTREAM.

`DecryptionParameters`

Decryption parameters. When decryption is not used, this structure is zero initialized. See D3D12DDI_VIDEO_DECODE_DECRYPTION_ARGUMENTS.

`hDrvVideoDecoderHeap`

Supplies allocations that may contain the state for the current decode operation.
