MoonlightOH

Yet another Sunshine client implementation on HarmonyOS Next.

Other port(s) I know:

• moonlight-harmonyos

Current state

• Add Sunshine server on LAN with static IP:port manually.
• Streaming 1080p with software H.264 decoder on Windows X86 emulator.
• Some ArkTS UI prompts are now triggered by Limelight runtime.
• Metrics overlay.
• Touch support.
• Decode and play streamed audio.
• Layered stream preference, global - server - app.
• Hook back action of streaming page to dialog for config and exit.
  • Exit, or end streaming.
  • Configure video stat hide or show.
  • Configure control methods.
• Virtual trackpad.
• Hardware decoding & HDR10.
  • On Pura 70 Pro, H.256 HDR10 decoding latency 2K typical ~9ms, 4K typical ~15ms.
• Virtual text input, holdable modifier keys and function keys.

Roadmap

No HarmonyOS Next hardware required:

• Configurable virtual macro buttons, remember it on a per-app basis.
• Configurable layout, remember it on a per-app basis.
  • Rendering area.
  • Virtual buttons.
• Configure default control method in stream preference page.
• More metrics.
  • Report estimated RTT via LiGetEstimatedRttInfo().
  • Report audio streaming stats.
• Support 16:10 resolutions or negotiate with Sunshine server.

HarmonyOS Next hardware required:

• mDNS discovery.
  • Currently the API is buggy, it returns empty-string for address and -1 for port, service name is correct though...
• Physical mouse and keyboard support.
• Performance optimizations.
  • Eliminate context switching, e.g. the render output thread.
• Support pen event.

Possibly will be supported by HUAWEI in the future:

• Controller over BLE / SLE, driver and wiring.

Personally not interested, however noted here anyway:

• WAN streaming.
• Virtual controller.
• Vertical streaming and automatic orientation switching.
• Handle stream change.
• Controller over USB.
