Stream a synthetic test pattern and silent PCM audio over the OBS Teleport protocol: - protocol: wire format (Header/ImageHeader/WaveHeader), BT.709 full range colour matrix, JPEG encode via turbojpeg cgo, WAVE packet builder - output: TCP sender with per-connection buffered channels and drop-on-overflow - discovery: multicast announce via peerdiscovery - cmd: teleportfling CLI with flags, test-pattern frame generator Verified end-to-end: OBS discovers and renders the stream with correct colours and motion.
