Struct gstreamer_video::VideoInfo

pub struct VideoInfo(_);

Information describing image properties. This information can be filled in from GstCaps with VideoInfo::from_caps. The information is also used to store the specific video info when mapping a video frame with VideoFrame::map.

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