Input Buffer Order Example 3
This section applies only to Windows Server 2003 with SP1 and later, and Windows XP with SP2 and later.
The VMR initiates a call to the driver's DeinterlaceBltEx function to use the device in Input Buffer Order Example 1 and Input Buffer Order Example 2 to instead combine 3 video substreams with a progressive video stream. The sequence of surfaces in the lpBufferInfo array are:
| Index position | Surface type | Temporal location | Layer location |
|---|---|---|---|
lpBufferInfo[0] |
Destination |
T |
|
lpBufferInfo[1] |
Progressive input |
T |
Z |
lpBufferInfo[2] |
Substream |
0 |
Z + 1 |
lpBufferInfo[3] |
Substream |
0 |
Z + 2 |
lpBufferInfo[4] |
Substream |
0 |
Z + 3 |
In the change from example 2 to 3, the video stream changed from interlaced to progressive and an additional video substream became active.
