Class
MaplibreNativeFfiDmaBufRingDescriptor
Description [src]
final class MaplibreNativeFfi.DmaBufRingDescriptor : GObject.Object
{
/* No available fields */
}A ring of dmabufs that the library allocates, for
maplibre_native_ffi_map_attach_dma_buf_ring().
Each buffer has the map’s size in pixels and a format and modifier from
formats. The library renders only DRM_FORMAT_ABGR8888 and
DRM_FORMAT_ARGB8888. A modifier can give a buffer more planes than its format
has, such as a plane of compression metadata, and the library takes any such
modifier that its GPU can render into and share.
See mln_dma_buf_ring_descriptor in the
C API reference.
