Struct gstreamer_video::VideoBufferFlags

pub struct VideoBufferFlags(/* private fields */);

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.

Implementations

impl VideoBufferFlags

pub const INTERLACED: Self = _

If the gst::Buffer is interlaced. In mixed interlace-mode, this flags specifies if the frame is interlaced or progressive.

pub const TFF: Self = _

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.

pub const RFF: Self = _

If the gst::Buffer is interlaced, then the first field (as defined by the TFF flag setting) is repeated.

pub const ONEFIELD: Self = _

If the gst::Buffer is interlaced, then only the first field (as defined by the TFF flag setting) is to be displayed (Since: 1.16).

pub const MULTIPLE_VIEW: Self = _

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.

pub const FIRST_IN_BUNDLE: Self = _

When conveying stereo/multiview content with frame-by-frame methods, this flag marks the first buffer in a bundle of frames that belong together.

pub const TOP_FIELD: Self = _

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.

pub const BOTTOM_FIELD: Self = _

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.

pub const MARKER: Self = _

The gst::Buffer contains the end of a video field or frame boundary such as the last subframe or packet (Since: 1.18).

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl VideoBufferFlags

pub const fn iter(&self) -> Iter<VideoBufferFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<VideoBufferFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
