DXVAHD_STREAM_STATE_FRAME_FORMAT_DATA structure (dxvahd.h)

Article
02/22/2024

Specifies how a Microsoft DirectX Video Acceleration High Definition (DXVA-HD) input stream is interlaced.

Syntax

typedef struct _DXVAHD_STREAM_STATE_FRAME_FORMAT_DATA {
  DXVAHD_FRAME_FORMAT FrameFormat;
} DXVAHD_STREAM_STATE_FRAME_FORMAT_DATA;

Members

FrameFormat

The video interlacing, specified as a DXVAHD_FRAME_FORMAT value.

The default state value is DXVAHD_FRAME_FORMAT_PROGRESSIVE (progressive frames).

Remarks

Some devices do not support interlaced RGB. Interlaced RGB support is indicated by the DXVAHD_INPUT_FORMAT_CAPS_RGB_INTERLACED capability flag. If the device does not support interlaced RGB, it treats all RGB input streams as progressive frames.

Some devices do not support interlaced formats with palettized color. This support is indicated by the DXVAHD_INPUT_FORMAT_CAPS_PALETTE_INTERLACED flag. If the device does not support this capability, all palettized input streams are treated as progressive frames.

To get the device's capabilities, call IDXVAHD_Device::GetVideoProcessorDeviceCaps and check the InputFormatCaps member of the DXVAHD_VPDEVCAPS structure.

Examples

HRESULT DXVAHD_SetFrameFormat(
    IDXVAHD_VideoProcessor *pVP,
    UINT stream,
    DXVAHD_FRAME_FORMAT format
    )
{
    DXVAHD_STREAM_STATE_FRAME_FORMAT_DATA frame_format = { format };

    HRESULT hr = pVP->SetVideoProcessStreamState(
        stream,
        DXVAHD_STREAM_STATE_FRAME_FORMAT,
        sizeof(frame_format),
        &frame_format
        );

    return hr;
}
