Submits one or more video frame buffers for DirectX Video Acceleration (DXVA) decoding.
Syntax
PFND3D11_1DDI_VIDEODECODERSUBMITBUFFERS Pfnd3d111DdiVideodecodersubmitbuffers;
HRESULT Pfnd3d111DdiVideodecodersubmitbuffers(
D3D10DDI_HDEVICE unnamedParam1,
D3D11_1DDI_HDECODE unnamedParam2,
UINT unnamedParam3,
const D3D11_1DDI_VIDEO_DECODER_BUFFER_DESC *unnamedParam4
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
hDecoder [in]
A handle to the video decoder object that was created through a call to the CreateVideoDecoder function.
unnamedParam3
BufferCount [in]
The number of buffers in the array that is referenced by the pBufferDesc parameter.
unnamedParam4
pBufferDesc [in]
A pointer to an array of one or more D3D11_1DDI_VIDEO_DECODER_BUFFER_DESC structures. For more information, see the Remarks section.
Return value
VideoDecoderSubmitBuffers returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | The video buffers were submitted successfully. |
| E_OUTOFMEMORY | Memory was not available to complete the operation. |
Remarks
The pBufferDesc parameter points to an array of one or more D3D11_1DDI_VIDEO_DECODER_BUFFER_DESC structures. Each element in the array describes a compressed video frame buffer that is submitted for decoding.
Each D3D11_1DDI_VIDEO_DECODER_BUFFER_DESC structure includes the following data:
The resource that will receive the decrypted and decode frame buffers.
A D3D11_1DDI_ENCRYPTED_BLOCK_INFO structure that specifies which bytes of the frame buffer are encrypted.
A pointer to a D3D11_1DDI_AES_CTR_IV structure that contains an initialization vector (IV) for the frame buffer data that was encrypted by using the 128-bit Advanced Encryption Standard CTR mode (AES-CTR) block cipher encryption algorithm.
Note
If the decode buffer does not contain any encrypted data, this pointer is set to NULL.
Note
This function does not honor a Microsoft Direct3D 11 predicate that may have been set.
