SetExternalOutputBuffers

Set externally-allocated DMA-BUF fds as GPU renderer output targets for a (surface, encoder target size) pair. Each per-client encoder owns its own pool of target-sized buffers; the compositor composites at native size, then GPU-blits (LINEAR) into each registered target so every viewer gets a zero-copy stream at its own physical viewport. Pass an empty buffers to clear a target.

Fields

surface_id: u32

target_w: u32

target_h: u32

buffers: Vec<ExternalOutputBuffer>

RegisterDownscaleTarget

Allocate a server-side BGRA “downscale target” for a per-client encoder that doesn’t import GBM buffers (NVENC, software h264, software AV1). After registration the renderer GPU-blits (LINEAR) the native composite into a target-sized BGRA image then copies it into a CPU-mapped staging buffer; the resulting frame is delivered as PixelData::Bgra sized at (target_w, target_h) so the per-client encoder consumes already-downscaled pixels. Sending the same (surface_id, target_w, target_h) again is a no-op.

Fields

surface_id: u32

target_w: u32

target_h: u32

ClearDownscaleTarget

Tear down the BGRA downscale target previously registered for (surface_id, target_w, target_h). No-op when none exists.

Fields

surface_id: u32

target_w: u32

target_h: u32
