gstvideo.video_info

Module for [VideoInfo] class

Types 1

Information describing image properties. This information can be filled in from GstCaps with [gstvideo.video_info.VideoInfo.fromCaps]. The information is also used to store the specific video info when mapping a video frame with [gstvideo.video_frame.VideoFrame.map].

Use the provided macros to access the info in this structure.

gstvideo.video_info.VideoInfo newFromCaps(gst.caps.Caps caps)Parse caps to generate a #GstVideoInfo.

bool align_(gstvideo.video_alignment.VideoAlignment align_)Adjust the offset and stride fields in info so that the padding and stride alignment in align is respected.

bool alignFull(gstvideo.video_alignment.VideoAlignment align_, out size_t planeSize)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.

bool convert(gst.types.Format srcFormat, long srcValue, gst.types.Format destFormat, out long destValue)Converts among various #GstFormat types.

void init_(out gstvideo.video_info.VideoInfo info)Initialize info with default values.

Constructors

this(void * ptr, Flag!"Take" take)

this()Allocate a new #GstVideoInfo that is also initialized with [gstvideo.videoinfo.VideoInfo.init]. Returns: a new #GstVideoInfo. free with [gstvideo.video_info.VideoInfo.free].
