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

frame

The frame which side data is added to.

Returns

The AVStereo3D structure to be filled by caller.

const char* av_stereo3d_type_name

(

unsigned int

type

)

Provide a human-readable name of a given stereo3d type.

Parameters

type	The input stereo3d type value.

Returns

The name of the stereo3d value, or "unknown".

int av_stereo3d_from_name

(

const char *

name

)

Get the AVStereo3DType form a human-readable name.

Parameters

type	The input string.

Returns

The AVStereo3DType value, or -1 if not found.
