Flags
VideoBufferFlags
data VideoBufferFlags Source #
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 Caps of type: video/... and caption/...
They can conflict with other extended buffer flags.
Constructors
| VideoBufferFlagsInterlaced | If the |
| VideoBufferFlagsTff | If the |
| VideoBufferFlagsRff | If the |
| VideoBufferFlagsOnefield | If the |
| VideoBufferFlagsMultipleView | The |
| VideoBufferFlagsFirstInBundle | When conveying stereo/multiview content with frame-by-frame methods, this flag marks the first buffer in a bundle of frames that belong together. |
| VideoBufferFlagsTopField | 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).

| VideoBufferFlagsBottomField | The video frame has the bottom field only. This is
the same as GST_VIDEO_BUFFER_FLAG_ONEFIELD

VideoFrameFlags
data VideoFrameFlags Source #
Extra video frame flags

VideoFrameMapFlags
data VideoFrameMapFlags Source #
Additional mapping flags for videoFrameMap.
Since: 1.6
Constructors
| VideoFrameMapFlagsNoRef | Don't take another reference of the buffer and store it in the GstVideoFrame. This makes sure that the buffer stays writable while the frame is mapped, but requires that the buffer reference stays valid until the frame is unmapped again. |

Instances
VideoMultiviewFlags
data VideoMultiviewFlags Source #
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.

| VideoMultiviewFlagsRightFlopped | The right view is horizontally mirrored. |
| VideoMultiviewFlagsHalfAspect | For frame-packed multiview modes, indicates that the individual views have been encoded with half the true width or height and should be scaled back up for display. This flag is used for overriding input layout interpretation by adjusting pixel-aspect-ratio. For side-by-side, column interleaved or checkerboard packings, the pixel width will be doubled. For row interleaved and top-bottom encodings, pixel height will be doubled. |
| VideoMultiviewFlagsMixedMono | The video stream contains both
mono and multiview portions, signalled on each buffer by the
absence or presence of the |

The different flags that can be used when packing and unpacking.
Constructors

| VideoPackFlagsTruncateRange | When the source has a smaller depth than the target format, set the least significant bits of the target to 0. This is likely slightly faster but less accurate. When this flag is not specified, the most significant bits of the source are duplicated in the least significant bits of the destination. |
