MF_MT_VIDEO_3D_FIRST_IS_LEFT attribute
For a 3D video format, specifies which view is the left view.
Data type
BOOL stored as UINT32
Syntax
GUID MF_MT_VIDEO_3D_FIRST_IS_LEFT = {0xec298493,0xada,0x4ea1,{0xa4,0xfe,0xcb,0xbd,0x36,0xce,0x93,0x31} }
Remarks
For 3D video, each video sample contains two views, which are designated first view and second view. The exact layout of the views in memory is indicated by the MF_MT_VIDEO_3D_FORMAT attribute.
| Format | First View | Second View |
|---|---|---|
| Packed side-by-side | Left half of the buffer | Right half of the buffer |
| Packed top-to-bottom | Top half of the buffer | Bottom half of the buffer |
| Multiview | Buffer index 0 | Buffer index 1 |
| Base view | Entire frame | Not present |
By default, the first view is the left view, and the second view is the right view. If the left and right views are swapped, set the MF_MT_VIDEO_3D_FIRST_IS_LEFT attribute to FALSE in the media type.
Note
In base view format (MFVideo3DSampleFormat_BaseView), only the base view is retained, so this attribute does not apply.
