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.
