Fields

fd: Arc<OwnedFd>

fourcc: u32

modifier: u64

stride: u32

offset: u32

width: u32

height: u32

va_surface_id: u32

va_display: usize

planes: Vec<ExternalOutputPlane>

All planes for this buffer (main surface + optional metadata planes).

nv12_fd: Option<Arc<OwnedFd>>

NV12 output for the compute shader. When present, the compositor imports it into Vulkan (as buffer if linear, as image if tiled), writes NV12 via compute, and returns Nv12DmaBuf.

nv12_stride: u32

nv12_uv_offset: u32

nv12_modifier: u64

DRM format modifier for the NV12 surface (0 = linear).

nv12_width: u32

NV12 surface dimensions (may be larger than width×height due to encoder alignment, e.g. AV1 64-pixel superblock alignment).

nv12_height: u32
