Module zwlr_export_dmabuf_frame_v1

Available on crate feature wayland and Linux only.
Expand description

a DMA-BUF frame

This object represents a single DMA-BUF frame.

If the capture is successful, the compositor will first send a “frame” event, followed by one or several “object”. When the frame is available for readout, the “ready” event is sent.

If the capture failed, the “cancel” event is sent. This can happen anytime before the “ready” event.

Once either a “ready” or a “cancel” event is received, the client should destroy the frame. Once an “object” event is received, the client is responsible for closing the associated file descriptor.

All frames are read-only and may not be written into or altered.
