#define AV_STEREO3D_FLAG_INVERT (1 << 0) |
Inverted views, Right/Bottom represents the left view.
Stereo 3D type: this structure describes how two videos are packed within a single video surface, with additional information as needed.
- Note
- The struct must be allocated with av_stereo3d_alloc() and its size is not a part of the public ABI.

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.
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.
int av_stereo3d_from_name |
( |
const char * |
name | ) |
|
Get the AVStereo3DType form a human-readable name.
- Parameters
-
- Returns
- The AVStereo3DType value, or -1 if not found.
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".
