Structs

ValidVideoTimeCode
VideoAggregatorParallelConvertPad	An implementation of GstPad that can be used with GstVideoAggregator.
VideoAlignment
VideoBufferFlags	Additional video buffer flags. These flags can potentially be used on any buffers carrying closed caption data, or video data - even encoded data.
VideoBufferPool	Implements
VideoChromaSite	Various Chroma sitings.
VideoCodecFrame	A VideoCodecFrame represents a video frame both in raw and encoded form.
VideoCodecFrameFlags	Flags for VideoCodecFrame
VideoColorimetry	Structure describing the color info.
VideoDecoder	This base class is for video decoders turning encoded data into raw video frames.
VideoDecoderRequestSyncPointFlags	Flags to be used in combination with VideoDecoderExt::request_sync_point(). See the function documentation for more details.
VideoEncoder	This base class is for video encoders turning raw video into encoded video data.
VideoFilter	Provides useful functions and a base class for video filters.
VideoFlags	Extra video flags
VideoFormatFlags	The different video flags that a format info can have.
VideoFormatInfo	Information for a video format.
VideoFormatIterator
VideoFrameFlags	Extra video frame flags
VideoInfo	Information describing image properties. This information can be filled in from GstCaps with from_caps(). The information is also used to store the specific video info when mapping a video frame with VideoFrame::from_buffer_readable().
VideoInfoBuilder
VideoMultiviewFlags	GstVideoMultiviewFlags are used to indicate extra properties of a stereo/multiview stream beyond the frame layout and buffer mapping that is conveyed in the VideoMultiviewMode.
VideoOrientation	The interface allows unified access to control flipping and autocenter operation of video-sources or operators.
VideoOverlay	The VideoOverlay interface is used for 2 main purposes :
VideoOverlayComposition
VideoOverlayCompositionRef
VideoOverlayFormatFlags	Overlay format flags.
VideoOverlayRectangle
VideoOverlayRectangleRef
VideoPackFlags	The different flags that can be used when packing and unpacking.
VideoRectangle
VideoSink	Provides useful functions and a base class for video sinks.
VideoTimeCode	field_count must be 0 for progressive video and 1 or 2 for interlaced.
VideoTimeCodeFlags	Flags related to the time code information. For drop frame, only 30000/1001 and 60000/1001 frame rates are supported.
VideoTimeCodeInterval	A representation of a difference between two VideoTimeCode instances. Will not necessarily correspond to a real timecode (e.g. 00:00:10;00)
VideoTimeCodeMeta

Enums

VideoAFDSpec	v1_18 Enumeration of the different standards that may apply to AFD data:
VideoAFDValue	v1_18 Enumeration of the various values for Active Format Description (AFD)
VideoAlphaMode	Different alpha modes.
VideoCaptionType	v1_16 The various known types of Closed Caption (CC).
VideoChromaMode	Different chroma downsampling and upsampling modes
VideoColorMatrix	The color matrix is used to convert between Y’PbPr and non-linear RGB (R’G’B’)
VideoColorPrimaries	The color primaries define the how to transform linear RGB values to and from the CIE XYZ colorspace.
VideoColorRange	Possible color range values. These constants are defined for 8 bit color values and can be scaled for other bit depths.
VideoDitherMethod	Different dithering methods to use.
VideoEndianness
VideoFieldOrder	v1_12 Field order of interlaced content. This is only valid for interlace-mode=interleaved and not interlace-mode=mixed. In the case of mixed or GST_VIDEO_FIELD_ORDER_UNKOWN, the field order is signalled via buffer flags.
VideoFormat	Enum value describing the most common video formats.
VideoGammaMode
VideoInterlaceMode	The possible values of the VideoInterlaceMode describing the interlace mode of the stream.
VideoMatrixMode	Different color matrix conversion modes
VideoMultiviewFramePacking	VideoMultiviewFramePacking represents the subset of VideoMultiviewMode values that can be applied to any video frame without needing extra metadata. It can be used by elements that provide a property to override the multiview interpretation of a video stream when the video doesn’t contain any markers.
VideoMultiviewMode	All possible stereoscopic 3D and multiview representations. In conjunction with VideoMultiviewFlags, describes how multiview content is being transported in the stream.
VideoOrientationMethod	v1_10 The different video orientation methods.
VideoPrimariesMode	Different primaries conversion modes
VideoResamplerMethod	Different subsampling and upsampling methods
VideoTileMode	Enum value describing the available tiling modes.
VideoTransferFunction	The video transfer function defines the formula for converting between non-linear RGB (R’G’B’) and linear RGB

Statics

BUFFER_POOL_OPTION_VIDEO_AFFINE_TRANSFORMATION_META
BUFFER_POOL_OPTION_VIDEO_ALIGNMENT	A bufferpool option to enable extra padding. When a bufferpool supports this option, gst_buffer_pool_config_set_video_alignment() can be called.
BUFFER_POOL_OPTION_VIDEO_GL_TEXTURE_UPLOAD_META	An option that can be activated on a bufferpool to request gl texture upload meta on buffers from the pool.
BUFFER_POOL_OPTION_VIDEO_META	An option that can be activated on bufferpool to request video metadata on buffers from the pool.
