Pixels are arranged with alternating pixels representing left and right eye views in a checkerboard fashion.

### GstVideo.VideoMultiviewFramePacking

GstVideo.VideoMultiviewFramePacking represents the subset of GstVideo.VideoMultiviewMode values that can be applied to any video frame without needing extra metadata. It can be used by elements that provide a property to override the multiview interpretation of a video stream when the video doesn't contain any markers.

This enum is used (for example) on playbin, to re-interpret a played video stream as a stereoscopic video. The individual enum values are equivalent to and have the same value as the matching GstVideo.VideoMultiviewMode.

## Constants

### GST_CAPS_FEATURE_FORMAT_INTERLACED

    #define GST_CAPS_FEATURE_FORMAT_INTERLACED "format:Interlaced"

Name of the caps feature indicating that the stream is interlaced.

Currently it is only used for video with 'interlace-mode=alternate' to ensure backwards compatibility for this new mode. In this mode each buffer carries a single field of interlaced video. GST_VIDEO_BUFFER_FLAG_TOP_FIELD and GST_VIDEO_BUFFER_FLAG_BOTTOM_FIELD indicate whether the buffer carries a top or bottom field. The order of buffers/fields in the stream and the timestamps on the buffers indicate the temporal order of the fields. Top and bottom fields are expected to alternate in this mode. The frame rate in the caps still signals the frame rate, so the notional field rate will be twice the frame rate from the caps (see GST_VIDEO_INFO_FIELD_RATE_N).

Since : 1.16.
