- config: validate port/quality/fps/source/stream-index ranges on load
and before engine start (flinger.Config.Validate)
- discovery: add Announce option to disable multicast (GUI checkbox,
CLI --no-announce); absent JSON key keeps the default true
- backpressure: count dropped frames in the TCP sender, expose via
engine Status and a live counter in the GUI status label
- docs: record M3/M4 decisions and X11 coverage via the portal backend
- internal/gui: settings form (name, port, source, quality, fps, audio)
wired to the flinger engine, config save/load, start/stop toggle
- system tray via Fyne's StatusNotifierItem: Show (raises window),
Start/Stop, Quit; left-click shows the settings window
- cmd/teleportfling-gui entry point
Verified on Hyprland: tray icon registers, start/stop streaming works,
window shows and focuses from the tray.
Move the capture/encode/send pipeline out of cmd/teleportfling into a
GUI-free Engine so the CLI and the desktop app share one implementation:
- flinger: Config/Engine/Status, audio+video+stats loops, pattern source
- config: JSON persistence at ~/.config/teleportfling/config.json
- cmd/teleportfling: thin CLI wrapper around the engine (same flags)
- golangci: extend exclusions to flinger/config
Capture the Wayland desktop via xdg-desktop-portal + PipeWire using
go2tv.app/screencast (MIT), and stream it to OBS:
- internal/capture: Capture/FrameSource/AudioSource interfaces and the
PipeWire backend (BGRA frames at monitor resolution, S16 48 kHz stereo
system audio)
- protocol: EncodeBGRA fast path producing 4:2:0 YCbCr JPEGs
- cmd: --source screen|pattern, --audio, --stream-index flags; real
capture feeds the existing sender
- share one wall-clock reference between the audio and video loops so
OBS receives aligned A/V timestamps (avoids multi-second latency)
Verified end-to-end: real desktop at 30 fps renders in OBS with
sub-second latency.
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.
