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.

AVFrame *

frame

)

Allocate a complete AVFrameSideData and add it to the frame.

Parameters

frame

The frame which side data is added to.

Returns

The AVStereo3D structure to be filled by caller.
