Add an audio source picker to the GUI so users can capture a specific
PipeWire device (sink monitor or microphone) instead of only the system
default output.
- vendor go2tv.app/screencast and patch the audio stream to accept a
target PipeWire node serial (PW_KEY_TARGET_OBJECT); the upstream lib
only ever auto-connected to the default
- capture: ListAudioSources enumerates PipeWire sinks/sources via pw-dump;
OpenPipeWire takes the selected node serial
- flinger/config/gui: AudioSource config field, persisted and exposed as
an Audio source dropdown (default output + enumerated devices)
Also fixes two pre-existing bugs surfaced by stop/start testing:
- engine Stop now waits for the video/audio/stats goroutines before
destroying the encoder (was a use-after-free SIGSEGV)
- Start/Stop now pause/resume the engine instead of tearing down and
re-opening the portal session, which the portal cannot reliably do
in-process (2nd CreateSession returned Ended/cancelled). Capture
session stays open across stop/start.
Add a Scale option (1.0 native, 0.5 half, etc.) that downsamples the
captured BGRA frame with bilinear interpolation before JPEG encoding.
Config carries the scale factor; the GUI exposes a Scale dropdown
(100%/75%/50%/25%) that applies live via SetConfig.
Verified: OBS displays the image at the reduced resolution matching the
selected scale, without restarting the stream.
Add config.LoadFrom/SaveTo for arbitrary paths and thread a --config
flag through both entry points:
- CLI: --config loads a file first; explicit flags override file values
- GUI: --config selects the settings file used for load and save
- tests for LoadFrom/SaveTo and default fallback
- 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
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
