Methods
gst_video_info_align
gboolean gst_video_info_align (GstVideoInfo * info, GstVideoAlignment * align)
Adjust the offset and stride fields in info so that the padding and stride alignment in align is respected.
Extra padding will be added to the right side when stride alignment padding is required and align will be updated with the new padding values.
FALSE if alignment could not be applied, e.g. because the size of a frame can't be represented as a 32 bit integer (Since: 1.12)

GstVideoMultiviewFramePacking
GstVideoMultiviewFramePacking represents the subset of GstVideoMultiviewMode 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 GstVideoMultiviewMode.

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.
