Function Documentation

		const SyntheticVideoScene &	scene,
		unsigned	tick = 0 )

renderSyntheticVideoScene()

QImage renderSyntheticVideoScene ( const SyntheticVideoScene & scene, unsigned tick = 0 )

nodiscard

Renders scene into a QImage::Format_RGB32 image of scene.frameSize.

Format_RGB32 is deliberate: its in-memory byte order is B,G,R,x on little-endian, identical to SPA_VIDEO_FORMAT_BGRx, so the PipeWire producer can memcpy rows without any conversion.
