frame ID to get access to the required
field. For multiview (the ‘views’
property > 1) the fields of view N can
be found at frame ID (N * 2) and (N *
2) + 1. Each field has only half the
amount of lines as noted in the height
property. This mode requires multiple
spa_data to describe the fields. SPA_VIDEO_INTERLACE_MODE_INTERLEAVED < 2 fields are interleaved in one video frame.
Extra buffer flags describe the field order. SPA_VIDEO_INTERLACE_MODE_MIXED < frames contains both interlaced and progressive
video, the buffer flags describe the frame and
fields. SPA_VIDEO_INTERLACE_MODE_PROGRESSIVE < all frames are progressive SPA_VIDEO_MAX_COMPONENTS SPA_VIDEO_MAX_PLANES SPA_VIDEO_MULTIVIEW_FLAGS_HALF_ASPECT < 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 SPA_VIDEO_MULTIVIEW_FLAGS_LEFT_FLIPPED < The left view is vertically mirrored SPA_VIDEO_MULTIVIEW_FLAGS_LEFT_FLOPPED < The left view is horizontally mirrored SPA_VIDEO_MULTIVIEW_FLAGS_MIXED_MONO < The video stream contains both

of left and right views is reversed SPA_VIDEO_MULTIVIEW_MODE_CHECKERBOARD < Pixels are arranged with alternating
pixels representing left and right eye
views in a checkerboard fashion. SPA_VIDEO_MULTIVIEW_MODE_COLUMN_INTERLEAVED < Alternating vertical columns of pixels

raw video buffers at the moment.
Specific view identification is via
metadata on raw video buffers. SPA_VIDEO_MULTIVIEW_MODE_NONE A special value indicating no multiview information. Used in spa_video_info and other
places to indicate that no specific multiview handling has been requested or provided.
This value is never carried on caps. SPA_VIDEO_MULTIVIEW_MODE_RIGHT < All frames represent a right-eye view SPA_VIDEO_MULTIVIEW_MODE_ROW_INTERLEAVED < Alternating horizontal rows of pixels
represent the left and right eye view
respectively. SPA_VIDEO_MULTIVIEW_MODE_SEPARATED < Multiple views are provided as separate
\ref spa_data framebuffers attached
to each \ref spa_buffer, described
by the metadata SPA_VIDEO_MULTIVIEW_MODE_SIDE_BY_SIDE < Left and right eye views are provided
in the left and right half of the frame
respectively. SPA_VIDEO_MULTIVIEW_MODE_SIDE_BY_SIDE_QUINCUNX < Left and right eye views are provided
in the left and right half of the
frame, but have been sampled using
quincunx method, with half-pixel offset
between the 2 views. SPA_VIDEO_MULTIVIEW_MODE_TOP_BOTTOM < The top half of the frame contains the
left eye, and the bottom half the right
