The video frame has the bottom field only. This is the same as GST_VIDEO_BUFFER_FLAG_ONEFIELD (GST_VIDEO_BUFFER_FLAG_TFF flag unset) (Since: 1.16). Use GST_VIDEO_BUFFER_IS_BOTTOM_FIELD() to check for this flag.
When conveying stereo/multiview content with frame-by-frame methods, this flag marks the first buffer in a bundle of frames that belong together.
If the Gst.Buffer is interlaced. In mixed interlace-mode, this flags specifies if the frame is interlaced or progressive.
Offset to define more flags
The Gst.Buffer contains the end of a video field or frame boundary such as the last subframe or packet (Since: 1.18).
The Gst.Buffer contains one or more specific views, such as left or right eye view. This flags is set on any buffer that contains non-mono content - even for streams that contain only a single viewpoint. In mixed mono / non-mono streams, the absence of the flag marks mono buffers.
If the Gst.Buffer is interlaced, then only the first field (as defined by the GstVideo.VideoBufferFlags.TFF flag setting) is to be displayed (Since: 1.16).
If the Gst.Buffer is interlaced, then the first field (as defined by the GstVideo.VideoBufferFlags.TFF flag setting) is repeated.
If the Gst.Buffer is interlaced, then the first field in the video frame is the top field. If unset, the bottom field is first.
The video frame has the top field only. This is the same as GST_VIDEO_BUFFER_FLAG_TFF | GST_VIDEO_BUFFER_FLAG_ONEFIELD (Since: 1.16). Use GST_VIDEO_BUFFER_IS_TOP_FIELD() to check for this flag.
Additional video buffer flags. These flags can potentially be used on any buffers carrying closed caption data, or video data - even encoded data.
Note that these are only valid for Gst.Caps of type: video/... and caption/... They can conflict with other extended buffer flags.
