List of possible 3D Types.

Enumerator
AV_STEREO3D_2D 

Video is not stereoscopic (and metadata has to be there).

AV_STEREO3D_SIDEBYSIDE 

Views are next to each other.

LLLLRRRR LLLLRRRR LLLLRRRR ...

AV_STEREO3D_TOPBOTTOM 

Views are on top of each other.

LLLLLLLL LLLLLLLL RRRRRRRR RRRRRRRR

AV_STEREO3D_FRAMESEQUENCE 

Views are alternated temporally.

frame0 frame1 frame2 ... LLLLLLLL RRRRRRRR LLLLLLLL LLLLLLLL RRRRRRRR LLLLLLLL LLLLLLLL RRRRRRRR LLLLLLLL ... ... ...

AV_STEREO3D_CHECKERBOARD 

Views are packed in a checkerboard-like structure per pixel.

LRLRLRLR RLRLRLRL LRLRLRLR ...

AV_STEREO3D_SIDEBYSIDE_QUINCUNX 

Views are next to each other, but when upscaling apply a checkerboard pattern.

LLLLRRRR L L L L R R R R LLLLRRRR => L L L L R R R R LLLLRRRR L L L L R R R R LLLLRRRR L L L L R R R R

AV_STEREO3D_LINES 

Views are packed per line, as if interlaced.

AV_STEREO3D_COLUMNS 

Views are packed per column.

Function Documentation

AVStereo3D* av_stereo3d_alloc ( void  )

Allocate an AVStereo3D structure and set its fields to default values.

The resulting struct can be freed using av_freep().

Returns
An AVStereo3D filled with default values or NULL on failure.
AVStereo3D* av_stereo3d_create_side_data ( AVFrame frame)

Allocate a complete AVFrameSideData and add it to the frame.

Parameters
frameThe frame which side data is added to.
Returns
The AVStereo3D structure to be filled by caller.
